CZ 21 has the best corner to corner sharpness of any wide lens for canon apart from the 24tse.

Don't forget to include the Samyang 14mm f/2.8 in that list. It is just as sharp as those two.

Oh, I almost forgot that lens, you just added one on my on-the-fence list:)

I'm very tempted with the samyang 14 but it has filter issues. Anything wider than 16 that doesnt?

None that I know of. If you only want a protection filter on it, doesn't matter that much, it's a cheap lens anyway.

My major question is: Will the Zeiss still be better than Canon at F8 on a tripod

It will

Photozone.de has same results.

I checked the comparison chart @the-digital-picture,to my eyes the difference is so subtle,the center resolution is even slightly better with 17-40.
Of course Zeiss beats Canon in the corners though.

I think in real world shooting the Zeiss might differ from Canon only in terms of color and contrast and "the feel", BUT, does it really?

I had a similar dilemma a while ago -short story, I got rid of the Zeiss and kept the 17-40 - I have copied my reasoning from another post below:

rusty.jg wrote in post #13325577 (external link)
The 21ZE is very very very good, without a doubt possibly the finest lens I've owned (bar the 100MP). However, I sold it.

I compared it against my old Voightlander color-skopar 20mm and my Canon 17-40. The Voightlander came closest and was sharper in some cases but I put that down to not having live view focussing on my old 5D. I did start a thread on it and it was pointed out that my Zeiss may not have been performing well - so I sent it off to Germany to be serviced - came back stating that it was perfect and no changes necessary.

The Zeiss was better than my 17-40 in the corners without a doubt but for the rest of the frame - not too much in it.

I would say the 17-40 gives me 90%+ of what the Zeiss did. Subtle colour differences do not mean much to me as processing wipes them out anyway. If I was only going to do a bit of curves adjusting and exposure gradients then maybe I would still have the Zeiss but I do a lot of processing so any subtle improvements are reduced. As for sharpenss, the Zeiss may have had the edge but nothing a sharpening script couldnt recover.

I also shoot a lot by the coast and sea spray is prevalent - I just didnt want to keep exposing the Zeiss to that kind of environment so weather resistance was a must.

There's also a lot of talk about the micro-contrast of the 21 - it might well be there but I just didnt see it. I have a 35ZE and also owned the 100MP - now on those I did see the micro-contrast but the 21ZE I just couldnt.

All of these just made me think my cash might be better invested in something else. Again, I'm not knocking the Zeiss, its awesome build and quality cannot be denied - its just it didnt suit me.

Is the Zeiss the best IQ 21 out there - I would say so, yes.
Is the Zeiss the best built 21 out there - probably, yes
Is the zeiss worth the eye-watering £1300GBP+ hmmm, for me, no.

Perfect corners and 2.8 are just things I dont need or can work around.

I would find it quite difficult to tell on an A2 print which was Zeiss and which was 17-40 on a processed image (excepting the corners which are a giveaway but you can always zoom out a fraction and crop in on the zoom to minimise that advantage). SooC would be a different matter though.

There's also those annoying TS-E lenses that are even sharper but also cost a good deal more.... (annoying because they're so damn good they pretty much destroy any other landscape lens for IQ - my opinion solely :grin:)

The lens hood only covers the top and bottom, the filter threads are readily accessible on the sides of the lens. Context: ZE 15

But, it makes the use of 4x4 and 4x6 filters impossible... Something many landscape togs will find as a deal breaker.

Aye, thats what I mean. If I cant use 4x4/4x6 filters its of little use to me.

the reason I haven't already pulled the trigger. You can get a CPL on it however, and that may work for most of what I want it for. We'll see.

I agree though, crazy decision to integrate it preventing removal.

Thank you all guys, thank you rusty.jg for the reasoning!

I just pulled the trigger and bought a 2nd hand 17-40(actually this is the second time that I bought this lens).
My reason is simply: If I'm gonna shoot landscape, that means I'm gonna lug my lens through the mountain valleys,
along the coast line,or into the desert and so forth. In that case versatility really means a lot, i.e. zoom,AF,weather
sealing. And it also wouldn't hurt too much to expose the lens to harsh environments because of its relatively low price.
No doubt the Zeiss prime would beat a Canon zoom in terms of IQ, but in my case the latter is just the more "suitable"
choice rather than the "better" one.

I will consider the Samyang 14 if I find 17-40 is not wide enough in the future. Anyway, thank all companies for providing us with good products for less money!
