Quick test: Zeiss 24-85/3.5-4.5 on Canon
« on: May 05, 2007, 11:05:42 pm »

To maintain autofocus, auto aperture diaphragm and EXIF, you can of course go with the manufacturer's lenses, or you can go with the Contax N series converted to EF mount

For example, the Zeiss Vario-Sonnar 24-85 has a reputation of an excellent "knock around" lens. It has great colour, little distortion at 24mm, and great performance across its zoom range. Here is a 24mm sample, Canon EOS 1Ds, wide open, DPP sharpening=3.


100% crop centre


100% crop, edge, wide open not as good as centre, but not bad at all.


85mm is just great.

Note: all these tests are done with autofocus. As you can see in the 85mm 100% crop wide open at f/4.5, autofocus is extremely accurate. I took two pictures with AF but both of them focused equally accurately. The exact center, which is where the AF point is, is the plane of the crane and the boat, but you can see the roof just a bit in front is starting to get outside of the depth-of-field. (Please click on the 85mm 100% crop to see what I am talking about.)

Mechanical quality is outstanding, with a predominantly metal construction, although most samples have a zoom creep problem. It will slowly zoom itself back to 24mm if the lens is pointed upwards.
