Out and about today testing the Canon 28mm f2.8. The images are pleasing with good colour balance. Stopped down the images were generally sharp with some minor softness in the corners. Wide open was still good at f2.8. Not bad for a 30 year old lens with dated coatings. Let us know your thoughts.
No AF, but no problems. With focus peaking and MF Assist on Sony A7, its still relatively easy to zero in on a razor sharp depth of field. The Canon EF 50mm F1.8 has admittedly a very indeterminate manual focus. But, once disengaged from the AF mechanism, it still moves freely. Great way to utilize Canon EF glass. Primes are still the best way to fully utilize the capacity of this sensor. Next step, legacy FD glass. Stay tuned.
This body is a such a gem paired with the Metabones Mark IV EF to FE mount. ICPix has been playing with the Sony a7 + EF glass and can report this body paired with this adapter gives really good results with all our EF lenses inclusive of Autofocus. We have tried the Canon 17-40 f4, 70-300 IS f3.5-5.6, 85 f1.8, and Sigma 10-20 f4-5.6. Its not all rosy because the autofocus can search a while especially in low light. WE also found that the only lens in our stable with no autofocus operation is a dated EF 50 f1.8 (plastic fantastic). But even this, as with all the lenses listed, can utilize manual focusing and in many cases relatively rapidly. This is due to the focus peaking function of the Sony A7. We were also able to use a 430EX Speedlite under manual control. We look forward to using this lovely combination on coming shoots and will post images as soon as we can. In the meantime check out a couple of reviews from our friends at The Camera Store and samples here:
