Lens for documenting / portraits at a wedding
Certainly the corner / border sharpness is less of an issue for narrow DOF shots. The reason for not focussing too much on DOF and including e.g. The 40mm is that at 1.4 or 1.7 that does open up the possibility of problems of having one part of a couple out of focus if he's standing a couple if inch...

Lens for documenting / portraits at a wedding
Most MF film wedding and portrait photographers used a Zeiss Softar Soft Focus filter on their lens at all times. No other SF filter came close. It had sort of raindrops all over it.... you can see them here: I've still got at least one 67mm somewhere that was made for the Contax.

Lens for documenting / portraits at a wedding
Following on from Smeggpants's comments, it just goes to show that it's important to understand the design ethos of a lens. Unfortunately manufacturers rarely come clean about it, so we have to find out all by ourselves. Clearly the Sigma 30mm f1.4 favours central sharpness and makes an ideal len...

Lens for documenting / portraits at a wedding
I'm very new and trying to learn a bit, and anticipate being in the position you describe at a friend's wedding later this year. I have a K-5 on the way with the kit 18-55mm lens. I'm trying to decide on a higher power zoom. While I'm really drawn to the 55-300mm I think this would leave me a bit...

SMC M 28 or 50mm for beginner?
Hi, my step-daughter is just about to get her 1st DSLR, a K100D with a DA 18-55 kit lens. Call me mean, but I really want her to have either a SMC M 28 or 50mm so she can learn to focus and compose the way we did! I am erring in favour of the f1.7 50mm, but was wondering what other forum members t...

SMC M 28 or 50mm for beginner?
I'd second the M50/1.7. It's an excellent lens and the extra speed at a slightly longer focal length over the M28/2.8 will make it easier to focus. It was the first MF lens I bought when I was (re)learning to manually focus on my DSLR and in retrospect, one of the most accessible MF lenses I ha...

SMC M 28 or 50mm for beginner?
If the camera to be used was a K-5 then it would be fine using M lenses. However the K100D doesn't meter them too well at all. Also the camera has to be told what the lens is. I feel it might be rather too much for a beginner. Even focussing an old lens on a modern body is tricky as they don't by de...

Infinity focus problem 50mm 1.7
I have an M version of Pentax 50mm f1.7. It works great in general, but will not focus on infinity. The close distance is not a problem, but the longest distance I can focus on is approximately 4m, and that is when the focus ring is set to infinity. Any ideas? Thanks

Infinity focus problem 50mm 1.7
It might have been taken apart and incorrectly assembled.

Infinity focus problem 50mm 1.7
hm, any idea how to solve it? Disassemble it and put it back together the right way ;) Easier said than done, I know. I usually don't disassemble lenses (currently busy with my second one) so not much experience and definitely not with the M50/1.7 Else contact a local repair center (others can...

Infinity focus problem 50mm 1.7
It may be the front element needing adjustment. I took a tamron 80-210 apart to clean off some fungus and when put back together could not get infinite in focus. I had to screw the front element further in and it sorted the problem out.

Not sure it they are identical, but here's a link to an article involving repairing a 50mm 1.2 M lens> http://grantharg.tripod.com/CameraRepair/M50mmfixa.htm

M50 f4 macro on K5
When you turn the aperture ring nothing happens. It only stops down when you push the lever on the side down and feels sort of sticky. It will not snap back.

When you turn the aperture ring nothing happens. It only stops down when you push the lever on the side down and feels sort of sticky. It will not snap back. It is faulty, send it back. Most likely it has oil on the aperture blades. Regards David

Faulty, send it back.

M50 f4 macro on K5
If the return postage is more than the cost. Chalk it up to experience and have a try at stripping and cleaning the insides. It can be done, even with fingers like popeye (mine) if you proceed carefully. Otherwise send it back as suggested above, would agree with David's analysis. Bernard

Centon 500mm Mirror Lens
For anyone wondering (as i have for years) whether a £30-£40 mirror lens can be any good? I can confirm that it can! It takes some handling, being fixed f8, totally manual and incredibly sensitive to movement, and focus, and where the light is. But in the right conditions it can produce really inte...
