I got my A7rII late August and have spent some time and money on lenses since that, here is what I wanted and what I got…
Analysis of needs/wants:
- General purpose lens like 24-105/4, perfectly sharp and no aberrations
- Wide angle zoom also f/4 very good
- Short telephoto, sharp at full aperture and no axial chromatic aberration
- Telephoto zoom, 70-400 mm, sharp at all focal length when stopped down to f/8
- Preferably Canon mount lenses as they can be used with a HCam/Mirex/Kipon T&S adapter
What I have now:
- Canon 24-105/4 as general purpose lens, decent but not truly great
- Canon 16-35/4 as wide angle zoom. Better than the other lenses I own
- Canon 24/3.5 TSE LII, this is my main T&S lens. Very useful, but my sample is not as sharp as my 16-35/4
- Sony 90/2.8G Macro, quite OK. Probably not as good as the Batis 85/1.9
- Sony 70-400/4-5.6G, this is an A-mount lens I have owned for a few years. Quiet OK.
Considerations for short telephoto lens:
What I wanted was really a highly corrected 85/2 lens. Foremost I wanted little axial chroma (the stuff that causes magenta/green fringing in out of focus areas). The Otus 85/1.4 would be perfect but it is large, heavy and expensive, being an f/1.4 lens. The Zeiss 135/2 APO was interesting, but I don't think 135 mm is my favourite focal length.
The Batis arrived and 85/1.9 was pretty perfect. I put an order on it, but also considered the Sony 90/2.8G.
After 2-3 months I still did not have a delivery date for the Batis, while the Sony 90/2.8G had some very positive reviews. So I cancelled the Batis and got the Sony. In afterthought I think the Batis would be sharper but the Sony 90/2.8G has full macro capability, a great bonus.
Considerations for general purpose lens:
This was a tough one. I have a Sony 24-70/2.8 ZA that does a decent service, but it is not great at all at the long end. Also, I wanted a Canon lens.
- Canon 24-70/2.8LII: Great lens but I cannot afford it right now, doesn't go beyond 70 mm. Also, I have seen two bad samples…
- Sigma 24-105/4 A: Not as good as the Canon lens, probably weak around 70 mm (?), 82 mm front diameter.
- Canon 24-70/4: Nice lens, but seems to have significant focus shift from f/4 (where I focus) to f/8 (where I shoot)
- Canon 24-105/4: Better than it's reputation. This is what I finally bought. Not as good as the 16-35/4 in the short and and far below the Sony 90/2.8G at the long end.
- Contax 35-135/4 3.3/4.5. A zoom lens for the Contax RTS system, very good at long end.
Consideration for a wide angle zoom lens:
This was easy - Canon 16-35/4L, no competition.
