Canon 14x32 IS Review
Canon’s revamped (ISIII) 12x36s are my current
favourite general purpose astronomy binocular. They’re light, bright,
sharp and comfy to use. Their stabilised images yield details of the Moon and
DSOs no hand helds can. But the basic design is over
a decade old now and they do have downsides – too much false colour (esp.
for daytime use in bright conditions), not enough eye relief and lack of full
waterproofing.
Enter Canon’s latest 14x32s. Similar in size and weight
to the 12x36s (i.e. much lighter than their other high power I.S. models) and
promising advanced new dual-mode stabilisation, I was excited to try them and
see what a decade of further development might bring to Canon’s I.S.
technology.

What’s in the
Box?
A Canon unboxing remains a prosaic affair compared to
Swarovski, Zeiss and Leica ...
Design and Build
The
Canon IS range now (late 2020) has no less than five different groups, though
all share a similar design and look:
· A new range of 32mm models featuring a different
type of IS derived from their camera lenses, including a 12x32 and the 14x32 on
test here
·
8x25, 10x30 and
the 12x36, which share a similar non-waterproof design, are light weight and
fairly cheap. The 12x36s are a ScopeViews Best Buy
for astronomy.
·
Premium 10x42s
which are fully waterproof, have special lenses and are mainly aimed at birders
·
Large, high-power
binoculars of semi-waterproof design, with ED lenses: 15x50 and 18x50
·
Recent small and
light-weight ‘pocket’ binoculars in 8x20 and 10x20 sizes
Body
Physically,
these 14x32s are very similar in design and materials to the original 10x30 and
12x26 models, which I’ve tested before. They are made in Japan, as are
the 12x36s and the 18x50s I’ve reviewed.
Not
only do the Canon 14x32s look different from conventional binoculars, they work
differently too. Instead of the whole body pivoting to accommodate different
eye spacing, just the eyepieces pivot. The hinge-less plastic body has the
appearance of an electronic gadget rather than fine optics, more like a Canon camera
in fact. But build quality is very good.
Canon
claim a weight of 775g for the 14x32s dry. I measured 820g including the two AA
batteries: a little heavier than the Canon 12x36s, but considerably less than
the 15x50s.
The
14x32s are almost exactly the same length as the 12x36s – quite a compact
binocular, as compact as many 10x42s for example. However, the body is much
fatter than the 12x36s (presumably to accommodate the new type of I.S.) and a
different shape, with the objectives integrated into the body structure.
The
body is also now moulded in one piece, which should help prevent water ingress.
Like the 12x36s, these don’t offer any other special sealing against
water, though. Compare the 50mm models, which are splash-proof and the premium
10x42s which are fully waterproof.
The
14x32s’ composite body is covered with a thin rubbery armour that helps
grip, but isn’t a fluff-magnet like some. It has a slightly different tone
of dark grey than the 12x26s, but is otherwise similar apart from ribbing on
the side for grip. The objectives are surrounded by thin protective rubber
‘bumpers’.
Other
changes from the earlier models include a different battery housing with a
push-fit rubber cover that should be easier to use with cold fingers or in low
light.
Focuser
The focuser on the 12x36s is really good – light,
smooth and accurate. Initially, these 14x32 were much worse but improved to end
up much the same, albeit with a slightly spongier feel, despite the larger
wheel. Like all fine optics, good focus is a real point and the focuser gives
confidence finding it.
The reason for the change in feel from the 12x36s may be the
way the focuser works. Both focus by moving the objectives, but the 12x36s move
them externally, whilst the 14x32s have an internal focusing carriage.
The dioptre is the Canon usual – you twist the right
eyepiece. But here it’s stiff to use. The trick is to leave the standard
I.S. enabled with a light click whilst adjusting it.
These 14x32s do focus very close, however – I measured
1.5m. Close focus to infinity is a fairly fast (considering how close they
focus) two turns.
Optics - Prisms
All
the Canon IS binoculars use a type of porro-prism (not the roof prisms more
commonly found on high-end binos), but their design
looks nothing like other porros, partly because these
are Abbe-Porros (Porro II).
Porro prisms are basically the type in your Grandad’s
old binos’, but they have serious advantages
over the roof prisms found in most modern birding binoculars. For one thing,
porro prisms don’t need mirror coatings, so they transmit more (and
scatter less) light. For another, porro prisms don’t need special phase
coatings to deliver high resolution. Thirdly, porros
typically deliver tighter star images with fewer ‘spikes’ than
roofs.
Optics - Objectives
The integrated 32mm objectives appear to sit behind plane
optical windows in this model – the same as the 15x50s, but different
from the more budget models.
Canon’s specs say that these have an astounding seven elements
in their objectives. Most binos have two or three. But
this number likely includes the stabiliser components, see below. However, none
of those seven elements include special dispersion glasses. Consider that
almost all binos from the mid
range up now include SD elements to kill false colour fringing.
What’s more, higher magnifications suffer more from false colour. Now add
in the fact that these have a premium price tag and are made by one of the
world’s leading optics manufacturers and it seems very odd that Canon
should omit this key feature. My best guess is that this is a marketing ploy to
avoid superseding their expensive high-end models.
As for the 12x36s, Canon say these use their premium ‘Super
Spectra’ coatings, but in fact they are different/better than the
12x36s’, with a more muted tobacco hue more like the best Alpha
brands’ (see comparison photo below).
Canon advertise ‘Super Spectra’ coatings for the
14x32 IS and 12x36 ISIII, but 12x36s’ much more reflective (i.e. worse).
Optics - Eyepieces
The eyepieces are fatter, but have smaller eye lenses than
the 12x36s – they look very like the 15x50s’.
Field of view is an acceptable, but far from wide, at 55.5° apparent, which translates to a narrow 4.3° true due to the high power. For comparison, this is the same
as the maximum field you can get out of a Tele Vue 85 scope, which usually gets
fitted with a finder!
Eye relief measures an acceptable ~14mm, much as claimed. But
for some reason it just doesn’t feel like it in use: I can’t see
anything like the whole field with my specs on.
Enough already with the fluff-magnet rubber eye cups! Why
can’t Canon learn from the European brands here?! The usual fold-down
Canon eyecups don’t work with my IPD either, because they’re much
wider than the 12x36s’: I have to fold them for use without
glasses. Fortunately, this works fine, otherwise these binos
would be almost unusable for me without my glasses on.
If you have a narrowish IPD like
me, try these before you buy them.
Optics – Image Stabilisation
All
Canon’s original I.S. binoculars – from the 8x25s to the
18x50s - work on the same principle: a computer detects movement and alters the
shape of a special flexible optical element to compensate and cancel the
jiggling your hands induce. You activate this system by simply pushing a
button.
These
new 32mm models have a different system derived from Canon’s cameras
lenses that features a dual-action stabiliser with two buttons: a regular I.S.
that permits easy panning and a ‘Power I.S.’ that attempts to
eliminate all movement from the view.
From
what I can find out, it seems as if this system has the computer change the
optical path by changing the offset between lens elements, rather than a by
distorting a single flexible element. This would explain both the chunky body
and the excessive number of elements Canon quote for the objectives (seven, see
above).
Quite
how the standard I.S. mode differs from the ‘Power I.S.’ I
don’t know, but interestingly these make a muffled clonking sound from
inside when moved about, which the older models don’t. Do they employ
passively sprung elements, like Zeiss’ expensive mechanical 20x60 I.S.
model?
An
any case, you would think that the new lens-offset system would alter the
wavefront less than a distorting element, so you might expect enhanced optical
performance from these (though the originals are excellent).
Accessories
These 14x32s have a semi-rigid case that’s both
classier and more protective than the 12x36s’ basic pouch.
However, the thin unpadded strap is the same budget item.
Canon do include a pair of AA batteries to get you started.
In Use – Daytime
Ergonomics and Handling
Handling isn’t too bad. They’re light compared to
the massive 15x50s and 18x50s, but noticeably heavier than the 12x36s.
The 14x32s have fatter barrels than the 12x36s and I found
them more difficult to hold securely as a result, with less finger left to find
the buttons and focuser. Those with bigger hands might well find them better.
The focuser works and has no actual problems like backlash or
vagueness, but I found it too spongy in operation.
To adjust dioptre, you need to click the stabiliser on, then
move your hand to make the adjustment. It’s not ideal. The dioptre
mechanism really needs to be centralised like Swarovski’s new NL Pures.
Any way you slice it, eyepiece comfort is poor. The eye
relief isn’t enough to allow you to view the whole field with specs on,
but specs off and the chunky eyepieces make these problematic if (like me) you
have a small inter-pupillary distance (IPD).
Image Stabilisation
The two-mode stabilisation is effective. The front ‘stabiliser’
button allows smooth panning, whilst the back ‘power stabiliser’
button tries to ‘glue’ the image and resist any movement, as if it
were a telescope. Meanwhile, the ‘power stabiliser’ does remove the
slow movements the 12x26s’ I.S. leaves in – it’s more like a
rock steady scope view (!)
Activating either I.S. mode causes a loud
‘click’; in the 12x36 ISIIIs it’s silent. But the 14x32s are
similarly silent in normal operation.
Compared with the larger 15x50 and 18x50 models, the
14x32s’ I.S. is less intrusive, quieter in operation and generated fewer
(though not zero) artefacts like jitter and focus shift.
I.S. performance is an improvement over the original in many
ways, but the ergonomics are worse. They have made the two buttons a different
shape and feel, but they are way too small. Finding them with thicker gloves on
will be impossible. The buttons are too resistant for my liking and too far from
the focuser as well.
However, these gripes are mostly negated by just giving
either button a quick push, leaving the I.S. enabled with an LED to let you
know. Then you can change your grip or operate the focuser no problem. This is
a convenient feature the 12x36s don’t have.
Styling svelter,
cleaner than the older models.
The View
The view is truly excellent for a high power binocular, in bright
conditions at least – apparently quite wide, very flat, pin sharp and
reasonably bright. But most striking is the extraordinary detail. I watch a
Wren ferreting through leaves in my local copse, 200m away. Crows squabbling
over fallen apples 100m distant reveal amazing detail – every feather and
glint of eye picked out with stunning resolution. Similarly, I watch a lame
Oystercatcher grubbing for worms in the field with scope-like views of his lame
leg and muddy bill. He should be out on the sands with his flock and I worry
about him, but that’s just me, softie that I am.
The two-mode stay-on I.S. does allow smooth, natural panning
in normal mode and you can almost forget these are stabilised – a great
feature.
Optical quality, as usual with Canon is very high in both
barrels and focus suitably snappy – an absolute point.
Depth of field is shallow, just due to the high
magnification. That field of view of 4.3° is narrow enough anyway, but with
specs on you’ll be lucky to get more than 3°
- these binoculars are (obviously perhaps) about the details, not the overview.
If
you need to get in close and see highly resolved fine detail with scope-like
stability, these offer a great view.
Flat field?
The view
is pretty much sharp to the edge, but incorporates a little distortion for
comfortable panning.
Chromatic Aberration
These
suffer from good old fashioned false colour – the way all binos were twenty years ago. In general use it’s not
too noticeable, but it is when viewing birds silhouetted against the sky - on
the wing or in tree tops.
What
does this mean in practice? I watch a crow in a tree a few hundred metres away
with these and the 12x36s. Both deliver amazingly detailed views of eye and
feather at this distance, but the 14x32s have noticeably worse false colour,
fringing the black glossy feathers with purple and green that mar the view.
Those apple and blueberry hues are even more apparent when focusing or panning.
You can
see this effect in the photo below, taken through the 14x32s – note the
false colour around bird and leaf.
At risk of
repeating myself, I just can’t understand why a new model in the premium
price bracket, and from Canon no less, doesn’t get the SD glass elements
found in pair of Nikons Monarchs at a quarter of the price.
In Use – Dusk
Another questionable design decision was 32mm objectives. They
work very well in bright daylight, but performance falls rapidly at dusk like
any other 32mm. Yes, the stabilised view makes up for lack of aperture to some
degree, but not enough. This makes them a less general purpose binocular than
the 12x36s, which gather 27% more light and work better in low light.
In Use – The Night Sky
Not for
the first time, a pair of high-power binoculars that has issues by day turned
out to be pretty good for astronomy. Even more surprising because, on the face
of it, an aperture of 32mm just doesn’t sound enough. But as with the
(admittedly much cheaper 10x30s), stabilisation makes up for lack of aperture
more than you expect: the shakes you get holding conventional high-power binos detract from both limiting magnitude and resolution
much more than you realise.
So it’s
a sharp and steady view, really very much like a small telescope. The field is
nice and flat for enjoying star fields and there is no nasty flare or ghosts,
even on a brilliant full Lunar disk. Meanwhile, focusing isn’t an issue
because you do it once and leave it. The lack of eye relief, as is often the
case, is less troublesome in the dark too. Their relatively light weight
compared to the 15x50s and 18x50s makes them easier to use over a long
observing session.
The
final advantage is that the two mode stabilisation is much more functional at
night – use the basic I.S. to pan about searching for things, then the ‘Power
I.S.’ for the best static view. And as I said above, it does provide a
more rock steady view than the 12x36s. Those leave in long slow movements,
whereas the 14x32s can give a completely static ‘telescopic’ view
on ‘Power I.S. Again, this is a minor difference by day, a much bigger
deal for astronomy.
One
downside to mention is that smallish true field – finding things via star
hopping and panning is more challenging than at lower powers. These aren’t for newcomers to binocular
astronomy.
The Moon
The Moon
is an obvious use case for these binoculars, so I’ll go into some detail
here. I spent several long sessions comparing them with the 12x36s and a pair
of conventional 10x binoculars, including on a 19-Day waning gibbous Moon one
memorable December dawn.
Compared
with 10x, or even 12x, the 14x magnification of these binoculars makes a big
difference on the Moon. I actually preferred both the quality of the
view and the stabilisation of the 12x36s – brighter, sharper and with
less jitter and I.S. focus shift. Still, 14x gave a more involving and
‘telescope-like’ level of detail. I could find most of the features
and craters in my ‘Photographic Atlas of the Moon’.
For
example, that 19-Day Moon revealed lots of features around Mare Nectaris on the
terminator, with Theophilus in sharp relief and showing its central peak. Nearby,
27km Mädler was clearly resolvable as a bowl-shaped
crater. To the south of Catherina, the 1000m high scarp of Rupes Altai was very
prominent, with a bright ray from Tycho shooting across it. Further south, Maurolycus revealed its
central peaks too and numerous craters around in the rugged southern highlands.
In the
north, I could make out Posidonius A within the larger crater. Nearby was
bright Menelaus, another medium sized crater, with the beautiful ray through it
that spikes across Mare Serenitatis to lonely Bessel.
On the
other side of the Moon, I could make out strange and ghostly Reiner Gamma and
brilliant Aristarchus.
With
stabilisation, a magnification of 14x allows real Lunar exploration. I spent
time referring back to my atlas to identify new features, just like I might
with a telescope.
Seen on
a phone screen, this image from my library shows roughly the level of detail I
observed.
Planets
Jupiter
showed a clean disk surrounded by its Galilean moons and bright Mars an intense
orange colour with no spikes or flare. So far so normal for binocular planets.
But it was Saturn that exceeded my expectations by showing the rings as clear
‘handles’ separate from the planet, just the way Galileo drew them,
not the vague saucer shape binos generally reveal.
Lastly,
I was able to track the ISS, positively identifying it by the 4 tiny spikes of
its solar arrays.
Deep Sky
More
than any other binoculars I can remember, the trick for deep sky observing with
these is to use averted vision. If you do, they can show you a lot. I recall
one strange instance where globular cluster M15 blinked out with direct vision,
blinked back in as a nice fuzzy blob with a dense core looking away.
Having
got that straight, I found and enjoyed all my usual bino DSOs. I found the Ring
Nebula with ease, the dumbbell too. With averted vision, the double cluster and
M35 through M38 in Auriga showed their characteristic star-blast patterns much
better than with lower mags or without I.S.
I easily
found other globular clusters, those enigmatic and ancient balls of stars on
the fringes of the galaxy, too. Besides M15 near Enif, I quickly located M13
and M92 in Hercules, despite being low to the horizon in December. They looked
much more interesting than the slightly fuzzy stars you see at lower
magnifications, with M13 clearly more diffuse, M92 less so but with a denser
core.
No need
for averted vision to enjoy a beautifully split Albireo and the silver
glitter-mist of the Seven Sisters. Those excellent porro optics do deliver
lovely pinpoint and brilliant star images with intense (not false!) colours.
Surprisingly, the Andromeda Galaxy looked good too, with its dense core picked
out and a hint of a dark lane looking away.
The
Orion Nebula however didn’t look as good as through larger apertures,
with less nebulosity on show than through, say, a pair of 15x56s – blame
the small aperture.
Surprisingly,
these 14x32s will probably show you more of the night sky and in greater
comfort than a pair of premium conventional 10x50s (unless you mount them of
course). They do work very well for astronomy, but use averted vision to get
the best out of them for deep sky.
Canon 14x32 IS vs Canon
12x36 ISIII
I’ve compared the 14x32s with the 12x36s throughout
this review, but let’s summarise the comparison:
·
The
14x32s have better edge sharpness
·
The
14x32s’ higher power is better for the Moon and small, bright DSOs
·
The
14x32s have slightly stronger stabilisation on ‘Power I.S.’,
slightly smoother panning on regular I.S.
·
Stabilisation
in the 14x32s is noisier to activate and has more artefacts, jitter and focus
shift, than the 12x36s
·
The
14x32s’ Spectra coatings are better than the 12x36s
·
The
12x36s are lighter and slimmer, so easier to hold
·
The
12x36s have lower (but still not ideal) false colour levels for daytime use
·
The
12x36s work better at dusk due to 27% more light gathering
·
The
focuser on the 12x36s is more fluid and less spongy
·
Eyepiece
comfort is better in the 12x36s, esp. for specs wearers
·
The
12x36s I.S. button is larger, easier to push, but the click-to-stay-on feature
of the 14x32s is so much more convenient
·
The
12x36s are a little over half the price at the time of writing
Apart perhaps from for specialised astronomy use – the
Moon, doubles and small DSOs – or other uses, like plane spotting, where
you need extreme resolution, I’d recommend the 12x36s.
Summary
The last few binos
I’ve reviewed have been getting so good that I’ve started to sound
like an extension of Canon or Leica or Swarovski’s marketing department.
No worry of that here because I found some downsides to these mostly excellent
Canon 14x32s.
Poor eyepiece comfort and lack of
waterproofing are significant gripes, but perhaps my biggest criticism overall is the lack of HD optics to combat
false colour. Most mid range binoculars costing half
as much have HD optics now. Canon more or less pioneered the technology, for
consumers anyway, with their fluorite lenses for Vixen and Takahashi telescopes
in the 1980s, so it’s bizarre they should exclude it here.
Nevertheless, these make great
astronomy binoculars. The level of pin-sharp detail available is quite
extraordinary, day or night. They have high quality optics and do offer a very
flat field and steady high-power views thanks to improved stabilisation.
So if you
enjoy astronomy but live in an apartment with nowhere to set up a telescope,
these binoculars might be a solution, especially if you find the 15x50s too
heavy. The extra power over the 12x36s does make for more involving views of
smaller DSOs and especially the Moon, it helps cut through sky glow too. The
lack of HD optics isn’t a problem at night either. But be prepared to use
averted vision to get the best out of them on deep sky.
If Canon’s old high-power models are too bulky and
heavy, but you want the extra magnification for astronomy, plane spotting or
whatever, these are a serious option. For general use I’d recommend the
cheaper 12x36s instead.
