Vivitar (Komine 28xxxx) 28mm F2.0 MC Close Focus Wide Angle Review
Vivitar_Top.jpg
Had the chance to buy the Vivitar 28mm f/2 Komine version for a good price because it is Konica version. It's quite small and feels good in the hand, but a bit odd due to the inner barrel which does not retract a lot at infinity. Beware of sticky aperture blades, mine is clean bit this is a common p...

Ricoh 28mm F2.8 Rikenon XR Review
IMGP6931s_r28.jpg
Bought a kit with multiple lenses for 50 $. It came in the bunch. Had issues with the f ring but with a bit of heat from blow dryer everything was good. beautiful build. Nice sharp pics. Why pay more.

Tokina AT-X 352 35-200mm f3.5-4.5 Review
Tokina35-200--1k.jpg
This review is for the SD version of this lens, with 62mm filters. It is very sharp, prime like, past F/8, with low distortion and minimal aberration. Bokeh is quite pleasant. It is light and compact for the zoom range. You do have to set the stabilisation distance manually. It has useful macro /...

Hanimex 135mm F2.8 Review
blah_2_.jpg
Found this lens at a thrift store for $4.99. There was also a 35mm f2.8 Hanimex for $4.99 that I picked up. The mount is M42, with an automatic aperture pin. I use an M42 to Pentax K adapter that has a flange to keep the pin from interfering with mounting the lens. The lens looks older than the o...

Samyang 85mm F1.4 Aspherical IF Review
IMGP00561.jpg
I just love this lens. I bought it as a portrait lens and it excels in that role. As a general purpose lens, it is pretty good as well. There seems to be a bit of a learning curve that one has to go through in order to get the best out of it. I, for one, is happy to do that. Manual focus can be tr...

Tamron 177D AF 28-80mm F/3.5-5.6 Aspherical Review
tamron177D-28-80-1a.jpg
nice combat lens, I like the range. It doesn't come close to my old ricoh 50mm 1.7 or pentax 100mm macro. But still I find I use it more and more. For the price I d buy it again.:rolleyes :

Sigma 30mm F1.4 EX DC Review
sigma30mm.jpg
When I originally looked for a good normal prime it was between this lens and the DA 35mm f/2.8 limited, and the limited won. A few years later I came across a copy of the Sigma for 200 and couldn't resist so I bought it and gave it a whirl on the K200D. I later sold it just before I bought my K3...

Sigma 30mm F1.4 EX DC Review
sigma30mm.jpg
I bought this because I found a bargain 200 minty copy, and its in my preferred focal length range - 27 to 30mm on APSC. I already have its monstrous big brother the 28mm f1.8 macro, but was not using it so much due to its massive bulk, even though the IQ from that lens is superb. The 30mm is much ...

Irix 15mm F2.4 Firefly Review
irix-15mm-f24-firefly.jpg
I purchased the Firefly variant as I decided I wanted to save some grams while hiking - haven't regretted that decision at all. This lens is awesome. It is the anchor of my lens collection, and I don't see myself being tempted to go wider. This fellow is wide enough to handle just about anything whe...
