Calling Tamron 10-24mm owners
I have a 10-24 and it's kind of interesting. It's not the sharpest. However, I already commented elsewhere: It's not about sharpness, it's about rendering. Sharpness also returns, I now know, at around f8-f16. My copy or my cam appears to backfocus slightly (the focus point represents the start ...

Samyang Lenses?
Hi there! I'm suffering a bit from LBA at the moment and surfing the bay for 85mms I stumbled upon a Samyang 85mm at a reasable price. Now, I don't need it (fortunate enough to have a 77 ltd and I primarily wanted to find out what my old 85mm Pentax could be worth) but the Samyang looked fine an...

Sigma 24mm F2.8 Superwide II - any recommendations?
I've used one of these lenses,together with a Sigma 50mm f2.8 macro,on a *ist DL and now a K7. Together they make a very nice lightweight manual focus outfit. I agree entirely with Mark D's summing up and would only add that you do need to use a lens hood just about all the time.

Sigma 50-500mm f/4-6.3 EX DG AF Lens Good Price?
All I can say Mike is that you have very steady hands:D They are lovely shots. Thanks, I have had a lot of practice, Pentax SR does make a big difference as well though, the main reason (as well as Pentax IQ) that I haven't jumped over to the Nikon D300. (Those long Nikon VR lenses are just a horren...

DA* 300mm - Shooting advice
Just acquired my first long prime, a DA* 300mm off eBay for £600 (can't believe no one else bid on it!), and was just wondering what advice would you give for using it and getting the best out of it as I have only ever used zooms at that length. Do you always use a monopod or tripod, prefer to go...

Pentax-F 35-70mm
I had one of these, sold it, regretted it, bought another one off ebay (I say bought - it actually came bundled with another lens and body, both of which I sold on at a small profit after fees.) I am simply amazed by the quality of this lens. Not only is it sharp across the frame and at either end...

Has anyone used a Pentax A on a K10D?
Hello, I just bought a 50mm 1:2 Pentax A lens to use on my K10D. When I attach the lens the menu pops up & asks for focal length, is this normal? I select 77mm as there dosn't appear to be a 75mm. I've set the lens to auto & it seems to work fine although I understand it will only work in manual f...

Once you have correctly set the focal length for a manual focus lens (50mm in the case of a 50mm lens), and if it is the only MF lens you have, you need do nothing more than press the shutter button to turn off the 'Select focal length' menu because the camera will 'remember' your last setting and u...

smc-Pentax M Lenses
A good 75-150mm is a very nice lens, but beware worn ones with very loose zoom/focus action. With the lens mount down the zoom/focus ring should stay at the top of its range without slipping downwards.
