Just posted: Canon EF40mm F2.8 STM pancake prime lens sample images. We've been using Canon's latest diminutive prime lens for the last couple of days and have prepared an image gallery of both full-frame and APS-C samples. These have been shot at a variety of apertures in a range of lighting conditions, using the Canon EOS 5D Mark III and Mark II for full-frame images, with APS-C shots taken with the Canon EOS 650D / Rebel T4i and 600D / Rebel T3i.

This is an amazing lens ... I've had it almost all the time in my 5d mkiii , been neglecting my 17-40mm and 70-200 f4L's due to their nasty weight. Been shooting strobist and natural light and am loving it, you can see my shots in my website.

One issue though is that my copy seems to be front-focusing, I fixed it by using 5d's micro focus adjust. However it's unfortunate for my 60d not have one >.< , I will send this to Canon soon.

Another issue is to be careful not to apply pressure at the lens front, since it extends like a 50mm 1.8, it will simply stop focusing if held with pressure - a quick fix is to remove the lens (or battery) and put it back again. A permanent fix is by applying the newly released firmware.

Enjoying the lens so far, I hope Canon makes more of these soon!! :D

Very interesting lens. From a pure image quality perspective, I'd rate it "very good" rather than excellent. There is some light falloff towards the edges; distortion is noticeable especially for a prime and also contrast isn't anything stellar.

That said, if you take into consideration the lens's price, and size, it starts to make a great deal of sense. I'll be buying one. Even if I only use it for a few hundred shots over the life of the lens, it'll have paid for itself in my view. Because of its size and price alone, I suspect it'll give me more sheer enjoyment than my $2000 L series lenses.

Actually no, scratch that. I've just re-looked at some of the images. It would qualify as excellent. :)

it's not bad.

Is it just me or are some of these images simply way out of focus?

0 upvotes

It does not seems so. Have you waited for the image to fully load? They do look out of focus before loading is complete, in your browser. :)

We can't complain about poor DPR sample shots anymore. Nice samples. Interesting lens. Maybe a 16 or 18mm in the future like this??

0 upvotes

At first I thought, nice shots. Oh look the Space Needle. I wonder if Richard took these? Oh... nice hike! :P

I'm jealous. I hope the Shorty Forty was fun. A bit awkward on a 5D - hoping for something a little more 'portable' soon.

Just received my pre-order, 231€ with shipping is really not a bad price for this one. Maybe I'll have some time to test it this weekend.
First thing I notice, is that the autofocus makes a really funny noise :D And it looks real small on my 5D Mark II.

Much better than expected...

Interesting lens. But this begs the question, why not just use a 50 1.8 or faster short prime? As someone pointed out, the lightest FF is 950g, is a slightly larger lens going to make much difference in usability?

1 upvote

I think it's that the pancake doesn't stick out much past the grip. So if you have a lens that's twice as long it actually sticks out significantly more past the grip. The 50mm f1.8 isn't really usable till F2.8 anyway so the speed advantage isn't an issue.

It's about fitting your camera in a small bag that isn't triangle shaped, you could fit this in a bag that is normally intended only for the camera body.

2 upvotes

This means I can pack my camera and lens into my computer bag. For me bigger factors than size were, 40mm is a 50mm fov on APS-H, much better out of focus highlights (I don't care for the pentagons), it's sharper than the 50mm across the frame (at common apertures) and it's same price as the 50mm Mk I (but you get a new lens).

The improvement in out of focus areas is enough that I'd reccomend it over the 50.

2 upvotes

impressed with the quality of the pictures. Certainly a very strong performer on full frame :D definitely will be picking one up as soon as possible.

1 upvote

the only drawback this lens has is that the "smallest" FF dslr weights 950g.

6D weighs 770g ;-)

Having used a pancake lens for a while, I can say these designs have virtues and shortcomings: they're nimble to use, practical and very fast to focus. On the down side they're usually not too fast - f2.8 seems to be the standard -, plus they tend to produce vignetting, chromatic aberration and softness at the corners. This, however, seems to have only a little - very little - vignetting. Exceptional for the price. If I had a Canon body, I'd buy this lens as soon as it hit the shelves.
While I think a pancake lens does make sense on a DSLR body, this lens could mean Canon has got something new on its way. Is it the MILC everyone is talking about?

"this lens could mean Canon has got something new on its way. Is it the MILC everyone is talking about?"

Logically, it must be.........

0 upvotes

Not so logical. We were expecting the mirrorless Canon early this year, instead we got the G1X... hence my reservations.

0 upvotes

the vignetting of 40/2.8 is much worse than zoom lenses.
a rumor says you might have a mirrorless Canon later this year.

0 upvotes

i have tested it yesterday.

it´s a fantastic lens if you can live with f2.8.
it´s very sharp from f2.8 onwards.. as writen in all reviews.

if only it would be f2.0 .. i would pay 500 euro for it with this image quality.

2 upvotes

in general, a one stop faster lens will be 2-3 times as heavy and 3-4 times more expensive.

or if you are looking for a similar lens for your Sony NEX, you should be able to have a 24/1.8 at about the same size, performance, and price if Sony is as honest as Canon.

0 upvotes

When using it on the new 5d III with the newest firmware 1.1.3. but also in the newest dpp there is no lens data available in order to correct vigneting and the rest. Hope that this is updated soon! (Aside this I love this lens!)

0 upvotes

At first glance the images don't look any better than the Pentax DA40, and definitely can't compete with the (admittedly more expensive) Pentax FA43. The FA43 is often classified as a pancake lens as well - especially without the lens hood. In fact, the FA43 is exactly the same length as the Canon (27mm) according to the specs.

But it's good to see Canon creating this lens, and dpreview reviewing it right away. The fact that it has STM is certainly impressive, and the price is so reasonable.

While the Pentax DA40 f/2.8 is very good, there is one problem: it is designed for APS-C and not FF. So, it's hard to compare.

As for the FA43 f/1.9, its performance is already severely compromised wide-open on APS-C. On FF, it's probably a disaster. :)

3 upvotes

Actually the DA40 works on Pentax's "full-frame" film cameras since it is actually an updated version of the old KA manual focus pancake lens. So, yes, this lens is remarkable like the Pentax lens only a little bigger. I've never used the FA43 but it was designed for a FF (AKA film) camera so I have trouble believing it would be a "disaster".

0 upvotes

@photo nuts - If the FA43 is better than the EF40 from f/2.8 on then it's still "better."

I'm not sure if you're speaking from experience, but I've looked at many FA43 photos (including my own) as well as many dpreview samples. The FA43 produces better shots without even putting much effort in. These EF40 shots aren't as nice, and it's not the fault of the photographer.

As I implied, the DA40 can't live up to the FA43 either.

I'd like to see all three compared here on DPR, even if it's only in the form of using the EF40 on the T4i review and the DA40 AND FA43 on the K30 review (especially since the two cameras are direct competitors).

And which Pentax FF body do you use it on?

1 upvote

Just lined up my collection of Canon bodies and tried to imagine what they'd be like to handle and transport with this pancake lens attached... Although my 20D, 30D, 50D, 5DmkII, and XTi are thick bodies, the lens would make the cameras slide much easier into small spaces and still be ready to shoot (having a lens attached)... where otherwise you'd have to either take time to attach a lens to the body after removing the body cap, or make much more room for a zoom. At about $200... it's hard to justify for that alone... but hell when did logic rule the day completely in our lives as photographers? I think I might bite someday when the need for "retail therapy" becomes necessary!

0 upvotes

In my experience, $200 is a very small price to pay for that convenience, but that's for me hiking up mountains with all my other gear (camera & hiking gear). It'll mean it has more chance of actually leaving home with me. No point spending $1500 on a lens that'll sit in a cupboard. Now, if they can just make a tilt/shift lens this small & light...

3 upvotes

If 40mm can be made so small, why not the rest of the lens?

0 upvotes

Because it is F/2.8. 35L is a monster comparing to this. F/2.8 lenses have been small forever, because there is nothing remarkable about F/2.8..... Now you start going to F/1.8 and it is hard to make a pencake that would cover a full-frame sensor

0 upvotes

actually, it becomes weird to notice that the thinnest pancakes are usually 40mm....

0 upvotes

Because of mirrors and angles of incidence of light on mirrorless sensors which restrict how near you can put lenses to the sensor plane. Aperture stops are easiest to design when they're close to the focal length of the lens from the sensor (really old rangefinder lenses will typically have the aperture stop exactly the focal length from the sensor). Putting the lens further from the sensor means you have to have a retrofocal design (requiring a large negative front element), putting it closer to the sensor is limited to perhaps half the focal length, but most people prefer fast telephotos which puts a minimum size on the front element too. I'm guessing it would be easy to design a nice small 85mm f/4, too but who would want one?

40-60mm lenses are the right focal lengths to not need substantial optical adjustment of the effective focal length, while not being so long that they require huge front elements to be fastish, and many people don't really care for 50-60mm lenses.

0 upvotes

More lens in the line is always a good thing. I dont see why people are complaining. If you dont like the lens then dont buy it. Im sure there are people that would be interested in it.

10 upvotes

So I paid about $1200 more for 2 more stops and 5 less mm... hmm...

1 upvote

I own this 40mm lens and I am craving the 35L.... There is no comparison, don't worry your $1400 was smartly spent. In fact, I'll eventually get the 35L despite having the 40

1 upvote

Ok thanks!! :-) I do love having f/1.4, and 35mm feels right to me.

0 upvotes

i dont understand the apeal of a pancake lens for a full size slr. i cant see this as being noticeable more portable than a 50mm1.8 attachted to any camera body

0 upvotes

Pancake on a DSLR makes little sense .... so what is Canon cooking next is the real question. Good looking lens anyway!

Whether the nifty-fifty is something you don't mind in comparison to this is all opinion, but as for size, this lens is definitely more pocketable on it's own. Just throw one in your pocket while the rest of your carrying capacity is dominated by larger lenses/other gear.
And to a minor extent, on the body it does help keep the camera from standing out as much, and that's of course for people who don't have/don't want to use other compact camera solutions.

if you don't see the appeal then don't try too, its either a no brainer to you or it isn't no right or wrong in that.

Sharpness aside (where it most likely beats the 50mm 1.8 at f2.8 and the f1.8 is soft wide-open). Bokeh aside where the 50mm 1.8 quickly degenerates into polygonal shapes where as the 40mm 2.8 is perfectly round from f2.8 to f5.6. AF motor sounds aside, where the 50mm sounds like a made in china wind up toy. Build quality aside where it looks like a made in china wind up toy. I just want an Auto focus hit rate that ain't nifty fifty fifty!

@Timbukto well i am nikon shooter and i havent tried canon 1.8 50 so youmay be right that is is crap. but isnt that a more solid arument to create a better 50 1.8 than it is to make alens like this?

2 upvotes

I agree with Kodachrome200. Canon should make good quality 50mm f/1.8 and f/1.4 already. The current f/1.8 is crap and the f/1.4 has a well-known mechanical design flaw. Nikon's 50mm lenses are perfect and very affordable, all of them. This 40mm doesn't make any sense to me.

0 upvotes

Nice samples and it looks like a heck of a lens. Favorite shot: the bottle of Pellegrino. It's a really well shot image. Good job.

1 upvote

Looks nice but I expected a bit more especially that this looks like it will battle head to head w/ the Pentax DA40 f2.8 Limited/ XS. Color looks great but not as sharp vs the DA40 (at least for me).

The bokeh when used with the FF seemed busy especially when compared to the ASPC, might be suited more for the APSC than the FF.

0 upvotes

Looks good, though some of the 5D shots look a little front focused. Perhaps a click or two adjustment is needed.

One Fine Lens :-)

I'd like to see a 1-1 comparison with a pentax da 40mm. This looks fine but with nothing to compare it to it doesn't tell us much.

0 upvotes

Go to photozone. Canon lens gets a highly recommended rating on a Full frame (it will be even better on APSC)

http://www.photozone.de/canon_eos_ff/752-canon_40_28_ff

so obviously it's pretty good optically.

2 upvotes

Hmm, it looks like it should easily beat the Pentax 40mm and its cheaper to boot !

Its good considering Canon has launched a string of high priced lenses lately so the only sub $500 lens they have launched recently is a stellar performer.

1 upvote

Nah, I don't think it can stomp on the Pentax 40 Limited right out, except on terms of price.

0 upvotes

Photozone gave it a similar scoring as the pentax(pentax a little more on build quality), can't compare the figures very well, because of the difference between FF and APS-C. Bokeh seems somewhat better on the Canon. Pentax also has a xs version of this lens at $249 which is even more compact and has the same optics.

1 upvote

The newer Pentax that came with K01 and is cheaper didn't perform as well as the older one . see

Much nicer than expected from a pancake, and a nice cross-section of subjects too. Thanks for getting these up. I'd love to see much more in the way lens testing on this site because virtually every manufacture now has a Silver or Gold award camera body. Now is the time for lenses.

Can you comment on whether these were PD-AF or CD-AF?

1 upvote

I'll check with the other photographers, but of the ones I shot, PT3C9288 on the 5D Mk III and IMG_0838 on the 600D were CDAF - the rest PDAF.

Work is being done to reintroduce lens reviews later this year - there'll be news on the front page when we're ready to announce something.

Thanks, great news about the lens testing. I love the interactive test results widget, it really gives a good sense of what to expect from a lens performance and of those lenses I have the result correlate well, so I am very likely to buy lenses on the strength of your testing.

1 upvote

All the 5DII shots (IMG_5xxx) were using PDAF.
