Minolta MD ZOOM 35-70mm 1:3.5 Review
I've read many reviews of old MF zoom lenses and the general consensus seems to be that old MF zooms are mostly poor by today's standards but with a few exceptions. I trawled the reviews and this was one that bubbled to the surface as one of those rare examples of an old zoom lens that is regarded a...

Sigma 28-80mm F3.5-5.6 II Macro Review
Sigma-28-80mm-1-3_5-5_6-II-Macro.jpg
Color & Contract are quite good at 28mm-35mm. Sticky zoom. AF hunts like pain in the ass. Tamron 28-200 is much sharper than this, with the same price. However , with 1:2 macro function, this lens performs quite good on bright daylight.

Tamron adaptall lens tripod grip ring Review
tamronTM-1.JPG
These crop up every so often, if you want one you'll have to browse around and keep your eyes open. They typically go for £10-15. Most useful I find for lenses like the tokina/vivitar 400mm f5.6 that dont have a TM. For the adaptalls, the cheap 65-66mm ID ones from China are actually more rigid.

Vivitar Series 1 70-210mm F2.8-4 Version 3 (komine) Review
2251521204_d89433152a_o.jpg
This is an early review after two days of use. I bought this A-mount lens in EX condition at keh.com, hence the high price. Gone are the good old days when it could be bought at a thrift store for $7. The internet has sprawled its tentacles everywhere, and everyone has become too clever. :( The lens...

Sigma 8mm F4 EX Circular Fisheye Review
8mm.jpg
I was surprised, it was better than I was expecting. Using the center point autofocus works consistently well on K-1 MII . Although there are sharper and more contrasty lenses out there, I find I end up using this often on K-1 for the circular fisheye effect. For daytime shooting, F7.1 seems to...
