Your favorite lens is?

70-200 f/2.8L II. As others have said, the bokeh and clarity is beyond words. Works in so many different applications and has always produced jaw dropping pictures for me.

It's a tie for the "top" lens - would have to be a 250/5.6 CFi Sonnar Superachromat on EOS adapter (on the long end) vs the 21/2.8 ZE Zeiss (on the wide end). Followed by the 110/2 Planar T* vs 100/2.8L IS. For pure macro, it would be a tie between the 120/4 Makro-Planar vs the 100/6.3 Zeiss Luminar on bellows.

All adapted to use on the 1DsMkIII. L-glass does the job, and does it well. But, as far as for personal shooting and my "favorite", it's definitely Zeiss.

After that, it's probably the Coastal Optic 60 and Hartblei Superrotators for EF mount. Then, would be the 24 TS-E II.

jcollett,

I just sold my t3i, 17-55 2.8 IS, and my soul to buy a 5DMK3 so I can capture low light video on the 8-15mm f/4L.  This lens deserves the best.

On crop camera, my favorite is the Canon 8-15 f/4L.  Full frame, I think I will love it even more.  The only thing I don't like about it is the lens cap.

If true, then your next purchase MUST be a FF camera.  Get a used 5Dc or 5D mark ii ASAP even if you need to sell other stuff to get it.  Once you see the 8-15 on a FF, the crop sensor camera you have now may never get used again!

24-105 f/4 L IS

[Jesse]

24 TS-E, will be the 45 TS-E when the new one comes out.

[dandai]

24-105 f4.0 L- 100 f2.8 L macro

[wayno]

24L2

Not the most practical lens, but the most unique.

[SJTstudios]

Canon 28mm 1.8 usm, best crop prime there is.

This is really a tough question.

After some time I settled with the lenses in the signature.
I love 35L as it is a perfect walk around lens. I can do some portrait without too much distortion when I come close and I can always move few steps away to get more people in the frame.
70-200 II on the other hand gives great results and sometimes I really love the compression effect. The only disadvantage as I can see it, is it's white color. I almost bought some black stickers or sleeve for it. I'm actually still thinking about it.
85L - magic.
Sigma 12-24   ...ah, no other lens in this category, serves the purpose especially @12-16mm f8-f11 but not as good as the above mentioned.

I guess 35L is the winner here.

[perperub]

So far, Canon EF-S 17-55/2.8 IS USM on my 40D crop.

24-105L... for the value you get with quality, capability, and price.
