Just picked it up today. I spent a couple hours this afternoon trying it out downtown. It exceeded my expectations, especially wide open. I played around with a set of extension tubes in the store, and this lens works great with them too. For anyone with doubts, this lens is a no brainer, unless you need f1.4, it is a better value than either of canon's 50mm's.

will there be a wider, faster pancake for canon in the future? I'm guessing that's the new trend, so it'll happen? 3rd parties will jump on this too?

I really want the 40mm 2.8, but I'd much prefer something wider and faster for me to leave it on my camera 90% of the time (which is what I'd like to do with a pancake lens).

Wouldn't a relative EF lens like that be interesting? http://photography-on-the.net ...hp?p=14743341&postc​ount=1 ;)

I went to take my Polariser off last night and it was stuck fast. Nothing i could do would budge it, and given how delicate the lens barrel is (or seems to be) i was terrified of breaking the lens.
It took almost 20 mins of swearing ( i find this method works best) before finally getting it off. I was thinking of breaking the filter apart but luckily its just a bit scratched around the outside. No marks on the glass.
It seems like there isnt much of a thread on this lens, so i tend to screw it on quite tightly. The fist time i used it i ended up turning the whole thing and the filter fell off.

When i put the lens back on i had the AF issues. The top display read 00 instead of the correct f stop. Took it off and re mounted it and its fine. I was pushing on the lens barrel quite a bit so its to be expected.

Anyway, all's well now. Still preferring this lens over my much loved 15-85IS.

What's this lens like on a crop sensor camera?

There are some crop owners posting in the archive thread.

really really impressed with what I'm seeing :o

for those of you with a CROP sensor who like to keep one lens on like 85% of the time, are you finding that this is a practical focal length for you?

All my shots are with a 60D, judge for yourself. Personally I love the focal length even though a lot of people say its too long (not sure how they know what I like but there you go:-))

is it pretty likely that canon will release a pancake 22mm f/2...or some other pancake in the near future for EF mounts?

I think there's speculation that these EF-M lenses will fit on our EF/EF-S mounts, with an adapter....will the adapter add on yet another crop factor (on top of if you're using a crop like a Rebel)?

I really want to love this 40mm f/2.8 and I'm sure I would---but only until Canon releases a wider, faster pancake lens...

If it uses the G1X sensor, yes, if it uses the full APS-C sensor, no. The crop factor is determined by sensor size, not by the adapter itself, which is more or less a glorified extension tube (no glass IOW). Canon already published a patent for such an adapter, BTW. Check here: http://www.northlight-images.co.uk .../Canon_aps-c_compact.htmlexternal link. Just scroll down to the (cool) adapter with 40 F/2.8 pic.

Other than that, we will just have to wait and see (till Monday I guess :D).

It is much harder to do a wider lens which is a pancake, because it will require a larger retrofocus aspect than the 40 mm. A larger retrofocus aspect essentially means more and stronger lenses at the back, and larger lenses at the front to accomodate the larger AoV. Much smaller than the old 24 F/2.8 and 28 F/2.8 will be rather difficult, let alone for even wider lenses, unless they are even slower than F/2.8 (F/4 and F/5.6 come to mind).

Kind regards, Wim

hmm, I see.... so the 22mm f/2 pancake is probably NOT gonna work according to this, right?

I would probably pay $400 for a 22mm f/2 pancake for our DSLRs..

Looks like there will be a 22/2 pancake in the near future. Will buy.
