Pentax SMC-D FA 100mm f2.8 Macro
I'm at work at present and just asked my girlfriend to check it for me and she said that there is a +1 magnification filter on it, which to be honest I hadn't realised. Do you think thats what's causing the issue with the focusing at distance?? That does sound like the smoking gun :wink:

CPL Permanently attached ?
I promise to end my LBA with my latest addition, a Sigma 10-20 f3.5 Given my ability to knock/scratch lenses I need to put a filter on it. My question is can a CPL be left permanently on the lens as a protector? (most of the time anyway) or am I better off with a UV type filter. they are blood...

CPL Permanently attached ?
How about just using the lens hood? If you're really so clumsy that you keep bashing the front of your lens, then sticking another layer of glass in the way probably won't help (you'll just break your filter and ram it into your nice new lens). Getting the filter off afterwards will probably just...

CPL Permanently attached ?
I put a UV filter on all my my lenses, cheaper to replace a filter than a lens. It happened to me once with my 10-20. The CPL will block too much light, and you can get dark areas of sky if the light is at the wrong angle. These block less light.

Close up filter
Has anyone ever successfully used one? I bought a 49mm +3 one from the Intro2020 eBay store and been trying it on the 50-200 WR lens, but I cannot get it to focus as all (AF or MF) - went up to f32 to get a wide dof as possible If I hand hold it in front of the sigma 10-20 it sort of works. ...

You will have to get quite close. A set of CU filters usually is a +1, +2 and +4, in combination they can provide any value up to +7. A +3 on its own should work, maybe you are just not getting close enough. I would set the camera on MKF, selct the closest point of focus and then just move inw...

I use a Raynox DCR 250 clip on macro lens- I usually use it on my SMC A 70-210- often at the longer end. Manual focus is essential- working distance approx. 4- 6ins, moving the camera rather than the focus ring. Quite a few of my macro shots in my portfolio are taken using this set up. Cheers, Gar...

the minimum focusing distance of the 50-200 is 1.1 m, so surely it won't focus closer than that? EDIT: it works! Moving the camera instead of fiddling with focus! Thanks guys

the minimum focusing distance of the 50-200 is 1.1 m, so surely it won't focus closer than that? That's the whole point of a close up lens. It enables you to move closer. With the CU lens in position though you won't be able to focus very far away.

Waste of time, better off just saving up and getting a dedicated Macro lens.

Waste of time, better off just saving up and getting a dedicated Macro lens Close up lenses afford a means for us to try out close up photography at low cost. Stopped down to f11 or f16 results can be very acceptable. If the bug bites, then eventually a macro lens may be the thing to go for.

Waste of time, better off just saving up and getting a dedicated Macro lens. I have found the Raynox quite acceptable- mind you I only dabble in macro,the Raynox is cheap and fun to play with-have a look at 'Robber 2' and 'Should Have Gone To..' in my portfolio Cheers, Gary PS. 'If the ...

+Dioptre closeup lenses / adapters change the focus distance of a camera lens. The host lens' focal length determines the amount of magnification. Cheap meniscus closeup lenses are not corrected for aberrations; corrected lenses like Raynox provide better images, but the cheap ones are fun, and usef...

Breasts!!! - Cool ;) I disagree Smeggy, I find them quite warm:D I personally feel the 50-135 is a bit big for a walkabout lens, and unless your going to spend a lot of cash on a cracking quality UV filter then you really need the lens hood in place, the front element of the 50-135 screams out "...

SMC-M 20mm f4 - scratched front element
The scratches are widespread, but very light. I will try it with a hood, but I doubt the original Asahi Pentax skylight filter it came with will help very much. A pity the owner didn't make more use of the filter! The lens has clearly had a lot of use :wink: Looking through my shots, blues seem e...

SMC-M 20mm f4 - scratched front element
A lens hood should stop most of the problems. Be careful using flash if it bounces back it will cause flare. It would be better if the scratches were in a diamond pattern that would make the lens work like a starburst filter.
