Sony FE 35mm f/2.8 ZA Zeiss Sonnar T*

Screen_Shot_2013-11-13_at_11_47_32_AM_copy
Review Date: Dec 9, 2013 Recommend? yes | Price paid: Not Indicated | Rating: 10 

Pros: Light and sharp!
Cons:
none

Sealed, small, light, sharp. Perfect combination with the very small 36MPx A7R. Sony/Zeiss did a great job with this little 35/2.8. AF is "solid", CA is low and flare resistance is great!

 
Tokina 10-17mm f/3.5-4.5 AT-X 107 AF DX Fisheye

Review Date: Jun 19, 2007 Recommend? yes | Price paid: Not Indicated | Rating: 10 

Pros: Sharp, very good colors, CA, flare
Cons:

I use it on an EOS 30D. The lens is extremely sharp from center to corner. The colors and contrast are a 10! When you use a lens with an angle of 180, in some pictures you can see the sun. But this lens is very resistent to flare. So these "sun pictures" have good contrast.

I think, pentax uses very high quality glass und a very good coating. Colors, contrast and resistance to flare are very good.

You can connect it to an EOS 5D, but then you have to zoom up to 16mm. And you can compare it against the Sigma 15-EX-Fisheye, and this Tokina Zoom is better! Ive not seen the Canon 15-Fish, some say, the Sigma where better.

AF is not as good as an USM, but it is fast enough, and the AF is relatively silent.
The zoomring turns the wrong way. :-(

Maybe some of you do not know, you can NOT compare this Fisheye against a circular fisheye, this Tokina makes rectangular pictures. A circular make round pictures.

And, 10mm of this Tokina are not the same 10mm of a Canon 10-22. The Canon only reproduces 107

Final: When you search for a Fisheye and you want the 180, there is no better lens out there for EOS bodies.

Canon EF 20mm f/2.8 USM

Review Date: Aug 4, 2004 Recommend? no | Price paid: $399.00 | Rating: 2 

Pros: colors
Cons:
sharpness, vignetting

Sorry, but this lens is not worth the money. Sharpness and vignetting are very poor. Bad in barrel distortion for a prime.
AF speed is okay, colors are good.
The Sigma 20/1,8 is much sharper at f/2,8 than this lens at f/8.
I can not recommend this lens.


 
Sigma 20mm f/1.8 EX DG Aspherical RF

Review Date: Aug 4, 2004 Recommend? yes | Price paid: $329.00 | Rating: 10 

Pros: Very sharp, build quality, very fast
Cons:
little bit warm colors in comparison to Canon lens, depends on slide film used

Extremly sharp. Better sharpness at f/2,8 than the very poor Canon 20/2,8 at f/8! Very good in comparison to 17-40L/4 too. And the corners are very sharp. At f/1,8 up to f/2,8 there is a little bit vignetting, but not very much - better than the other lenses.
Manual focusing is very smooth, and there are two steps to change from AF to MF; sometimes, this is an advantage, sometimes not. AF speed is okay, not very fast. For me, it seems that the USM mechanism of the Canon 20mm is fast, because you cant hear it. In reality, the speed is similar. But the 17-40 is faster.
When I did a comparison shooting, I noticed different colors between the Sigma 20/1,8 on one side and the Canon 20/2,8 and the Canon 17-40L/4 on the other side. The Sigma gives a warm (brown?) touch and both Canons are a little bit cool sometimes. I am not sure, which one is better, I think the Canons are more realistic. The difference is small, all three show very good colors. When I use Fuji film, the Sigma has a small advantage.

Bokeh is excellent wide open (Sigma), I did not test both Canon lenses.

Finally I bought the Sigma, because of its sharpness, the very small min focus distance, and because I am very happy with my other Sigma EX lenses, they give me very good results.

(Im using this lens on a full size body, only on slide films.)

Package includes lens hood :-)


 
Sigma 70-200mm f2.8 EX APO IF HSM

Review Date: Dec 28, 2003 Recommend? yes | Price paid: $900.00 | Rating: 10 

Pros: Very good contrast, very sharp! Good handling (focusing & zoom). Good AF speed. Price. ***Highly recommended***
Cons:
bit heavy to carry around all day long

I'm using this lens on an EOS50. The slides are extremely sharp and show very good and natural colors. Digital scans (10megapixels) are of top quality. APO correction is very good but not perfect in extreme conditions.
AF is very quiet and fast, could be faster. (but it is not slow, you know what I mean).
Maybe IS would be nice in low light.
When I use the 2,0x Sigma converter, picture quality is not as good. Then the quality is similar to those cheaper 100-300 lenses or so. (compared on tripod).

All in all, I think, this is a very good lens and it is hard to find a better one. Other Sigma EX are not as good, all Canon non "L" are not as good. And in my comparisons, I'm not sure, if the "L"s are better.
But buildquality of the Sigma is 4 and the Canon is a 5.
Finally I would be happy if I could find a 28-70 (or something like that) in the same high quality than this SIGMA 70-200 is.
