| Tamron 17-50mm F2.8 SP AF XR LD Aspherical IF Di II Review |
Set this lens to f/4 or higher and it’s very sharp corner to corner throughout the focal range. Set to f2.8 it’s not much different just slightly lower sharpness in the corners but the corners are still good; again throughout the focal range. Something almost all Standard zooms struggle with, but no...
| | | Irix 15mm F2.4 Blackstone Review |
Had a problem with a used copy and had experience with Irix Customer Service regarding that lens (damage caused by the U.S. Postal Service which welched on the insurance payoff), and Irix was outstanding. I'm not saying that merely in contrast to Ricoh's nonexistent customer service, but with respe...
| | | Pallas 28mm f/2.8 Magenta AM M42 Review |
I bought this lens on ebay for a joke and a low price. My copy looks beyond praise. Genuine leather cover !!! and a limited edition cap. It is heavy and durable. But the picture is somewhat boring. Most likely he loves bright light. On K1 it goes almost to infinity. But this is rather the trouble of...
| | | Tamron Adaptall-2 28-70mm f/3.5-4.5 (59A and 159A) Review |
59A version. Nice little walk around lens very suited to a light M series camera. I much prefer the two controls to a twist and slide zoom ring. Does feel somewhat plasticky, but has perfectly acceptable optics. My substitute for the optically excellent but bulky and slow autofocus 35-70 that the ME...
| | | Tokina AF 19-35mm f/3.5-4.5 (193) Review |
Bought this lens used but in mint condition from Ebay. It came with lenshood, original caps and blue pouch. As soon as I tested the lens, I immediately replaced the 18-55mm kit lens. Sharpness is really night and day by comparison although you miss the weather sealing. I am willing to take its weigh...
| | | Cosina Cosinon-S 50mm F1.8 Review |
Looks like a pretty good lens, especially for that time. I bought it second hand around 7y ago when i bought my first Pentax, a KX with 18-55, and cannot afford an AF prime lens at that time... i used rarely for a couple of portraits and deposit on a box... today i found it and i said to myself... '...
| | | Tamron (adaptamatic/fixed mount) 300mm f5.6 Review |
This lens is absolutely underated it is at f/8 sharpness is comparable my canon RF 70-200 f/4L. It definitely has its weight to it but it is manageable and if you do wildlife on a budget get this lens you wont regret it.
