New Canon UWA lenses (EF 16-35mm f4 L IS USM, EF-S 10-18mm f4.5-5.6 IS STM)
#1
They look to be rather impressive ultra wide angle lenses (according to the MTF's).

It was about time - the 17-40L is a bit weak at 17mm.

#3
Yes, the MTF's promise this to be a better lens than the rest of them. It did put on some weight, though.

#4
That 10-18 is likely on my shopping list! Within the usual cautions of cross comparing MTF charts, I wonder how it compares to the older Sigma 10-20, as that is what I never got around to replacing. I just want good enough at low price in this area.

I'm with popo on this one - the 10-18 is very likely to get on my shopping list. I've been eying the Sigma 10-20 just always been irking a bit at the price. And this one is even cheaper and with IS. I see a plastic mount there but that won't prevent me from buying it. If it is any similar to the other budget Canon lenses (18-55, 55-250...) then should be a good deal...

 

That is if the MTFs prove to be as good as advertised. Which leads to the obvious question of the PZ testing - any feedback on whether these will be tested soon or at some time in the future?

#6
The wide open MTF doesn't look anything special, but at f/8 it is as good as I'll ever need, plus the extra DOF wont hurt. Just like the old Sigma 10-20 was...

 

I hope it is cheap enough to buy and test soon after availability.

That makes me wonder - Klaus, did you ever think of adding block diagrams to your reviews (probably on the first page of each) if they can be easily sourced? While a block diagram won't say much to most of us (certainly doesn't tell me much WRT expected lens performance), it could be a nice touch.

#8
If it doesn't "say much to most of us", what's the point of making the pages larger? :wacko: Decorative reasons? Work increase to the editors should have a reason. I appreciate very much on the PZ tests, that one gets necessarily informations without much clutter around.

Lens construction diagrams will pose a copyright issue in german law (some silly judge made a ruling that linking to images is copyright violation for german websites). So the only way would be to draw them oneself...
#10
Images are generally under copyright - not just in Germany.

If the block diagrams are available as "press images" there would be no issue but this isn't really done too often.
