Brief Comments Re Canon Lenses on Sony A7r

So I bought a chinese adaptor off Ebay for running some Canon glass on the front of the Sony A7r.

Before I give a synopsis of the lenses I listed previously I will say that, with any of the lenses that interest me more from the list i will post some examples and RAWS in the near future. if you have any specific requests leave a comment and I will see what I can do.

Canon 24-70mm II 2.8 - Very good. Better then the E mount 24-70 f4 but obviously with the associated drawbacks (namely weight and size). Better corners and edges. Maybe not quite as good on the colour but PP fixes that easily.

Zeiss ZE 21mm 2.8 - Awesome. I love this lens and its even better on 36 megapixel. Love it

Zeiss ZE 100mm 2.0 - Awesome. This lens speaks for itself and holds up as expected on this camera

Canon 17-40mm f4 - Disappointing. Leats face it, its not Canons finest hour and it gets pulled apart even more on this sensor. Only the very very centre is great and gets progressively worse as you move off centre very quickly! Corners are rubbish.

Contax 35-70mm f3.4 - Very very good. Again I love this lens and the quality of its drawing. Holds up very well. For example @ 35mm it beats the E mount 35mm Zeiss. Beats the 24-70 Zeiss generally, although the later has beeter coatings/colour but again this can be rectified in PP.

 Canon 24mm II TSE - Awesome++ - Doesnt get any better for corner to corner sharpness. Shows what Canons newer glass technology is capable of. Biting sharpness.


  1. Hi !

    What adatpor did you use ? I'd love to buy an A7, but the lack of lenses is holding me back (and i fantasize on canon glasses). Do you think an adaptor is a viable option for everyday use or is it "clumsy" ?


  2. I bought a King adaptor off Ebay. Its not viable for everyday use if you wish to have autofocus but for landscapes that are manually focused its absolutely fine..

  3. Thank you very much :)
