Below is a list of lenses that I've tested. Most numerous are Sony, Minolta, Konica Minolta, Sigma,Tamron, along with the Olympus and Panasonic 4/3 system.
I review all lenses thoroughly
after extensive field use. Many of the lenses below are owned by me, though some are rented or purchased on eBay and
then sold. I use the image crops in the reviews to back up my written results, but don't take these as absolutes.
I sometimes have to go to extremes to make a lens reveal its minor faults, you should consider this, and how you intend to
use the lens before making a purchasing decision. The conclusion at the end of the review will let you know what I think
about the use, optical performance and value of that particular lens.
Unless otherwise noted; all tests for Sony mount lenses were done using the Sony 12.2mp A700, Sony 16.2mp A580, Sony 24mp A77, and the Sony 24.6mp A900 for full frame results. For NEX; C3; for micro 4/3, Olympus EM-5.
Specification sheets are compiled using the original owners manuals for each lens if available.
A note on
the macro test shots. I've stated measurements from the front of the lens barrel to the subject, as opposed to
the normal sensor plane to subject. I thought lens barrel distance would be more useful to the average person,
thus the discrepancy in the specification sheet and my own distance numbers, though each are
One last note; I've posted the full frame results separately at the bottom of each lens review (except "DT"
lenses), so there isn't any confusion with APS-C results.
