|comment:||This is a recent e-bay purchase, and it was purchased based on reputation. I wanted to compare it to the other lenses I own in this range using my a580. I used a remote shutter release for all shots, camera on a tripod, natural window light. ISO 400 for all shots. comparisons of near 1% center crops (535x804 pixels) were done.|
First the good -
28mm - I compared to the 18-55 SAM and 24-105 D this lens is sharpest at f4, 5.6, and f8. Colors are very slightly better than the 24-105.
50mm - I compared to all the listed lenses. Sharpest of the bunch at f4 and 5.6. At f8 the SAM and 24-105 are sharper, and at f11 everything except the 18-70 is sharper.
note - One of the 50's is not as sharp as the other. I need to clean both 50's and try again.
Now the bad -
85mm - Not as sharp at any f stop compared to the 24-105D.
Conclusion - I'll keep this around for the excellent performance between 28 and 50mm, but for longer focal lengths I'll reach for something else.
