Yea I saw that; but they did not comment on vignetting (which is usually one of the weak points of flat lenses).

Most impressive is the smooth bokeh, usually pancake lenses are not great in that area.

A 40mm f/2.8 and you are talking about the bokeh ? Frankly at this focal length and this aperture it is almost worthless to talk about this.

Nyce and trendy lens.

Unfortunately I don't understand wha you can do with it.

I suupose that this lens need to be attached to camera - even more to canon EF or EF-S cammera.

1. EOS xxxD - funny and trendy lens. I called trendy because now we are moving from "Bgger is Better" hype to "smaller is nyce". but this lens doesn't offer nothing special than kitlens 18-55 is



2. on xxD - is even more funy

3. on 7d - no comments here

the fun on EF/ FF mount is even bigger

4. Canon 5D MKIII

5. Canon 1D



Maybe it is just me, but i cannot find cammera where you can attach it. What anoth PZ fellows think about it.

Does it mean that we should expect something new and trendy from Canon

I really see no problem with this lens. It's small. It seems to be decent within its specification.



For general usage, I think it makes sense on a full frame body and I'd have no issue using this on a 5D2. If Canon go ahead with a lower cost full frame body, perhaps smaller than the 5D series, that would be a good pairing too. I'm sure it'll work fine on a crop body too, but I'm not sure what I'd do with that region of focal length.



Bokeh wise, I think it does have potential if you do lots of smaller scale close up work. Traditionally people I know use the 50mm f/1.8 (optionally with extension tubes) in a similar role, as a low budget option. While the 40mm f/2.8 would be approximately half the blur potential (dependant on various conditions of course) it does focus closer than the 50/1.8 without modification.



My only gripe remains the insane pricing for UK (probably euro too) compared to US. Ok, we long complain about the differences, but this is the first time I think I have seen the UK figure to be numerically bigger than the US figure without changing the currency units! And we used to joke about 1:1 rates...

Many Pentax users like DA 40mm f2.8 prime. One might check PF lens review database [url="http://www.pentaxforums.com/lensreviews/SMC-Pentax-DA-40mm-F2.8-Limited-Pancake-Lens.html"]here[/url], and actually it is almost the best rated DA prime lens by users. Small, light and sharp - what else we need <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/smile.gif' class='bbc_emoticon' alt='' />? Ok, shallow DOF, but it is the same as in fast zoom, and finally this is not a portrait lens. I am sure pro's might have another opinion, but from amateurs point of view such lens is very welcomed. If I was Canon user, I would seriously considered this lens.



A.

I have a PoV problem with this lens. Everybody gets excited about the size and price. I see it as a slow and expensive lens (compared to the 50/1.8).

Yep, have to agree. See [url="http://forum.photozone.de/index.php?/topic/1169-close-ups-with-wide-angle-lenses/page__view__findpost__p__19007"]the shot I posted yesterday[/url] in the "Close-ups with WA" thread. That one was shot stopped down considerably, well beyond f/2.8, and with an even wider lens.



Even with a comparatively slow lens one can still create lots of background blur, it's simply a matter of camera-to-subject and subject-to-background distances. Of course the lens needs to be able to focus rather close (the EF 40/2.8 does).
