I am considering the purchase of the Sony Zeiss 85mm f/1.4 SAL-85f14z. I am a Sony a900 owner. I have read the online test results (8 or so, see the list on http://www.dyxum.com/lenses/detail.asp?IDLens=317), but thought I would ask the readers and members of this forum to share their impressions of the lens on a full-frame, 24 MP camera - the Sony a900 or Sony a850. I would like to use the lens for landscape photography. If you have used the lens, please share your experiences and viewpoint on it. I'm particularly interested in:
• Sharpness - in general and especially in the corners. Any comparisons to other lenses (e.g. the Sony Zeiss 135mm f/1.8 or the 24-70 mm f2.8) would be especially helpful. My most common f-stops are 5.6, 8, and 11. I will shoot at f4 once in a while.
• Chromatic aberration
• Coma and astigmatism
• Autofocus. I've read that the autofocus of this lens can be problematic
If you have any lenses between 70-120 mm that you prefer over the SAL-85f14Z please let me know.
Much appreciated. Thank you
