Ghosts II
Well those are certainly the best reasons to use a UV filter but if you are also using the ND then I think its unnecessary. It is light being reflected onto the back of the filter. You see ghost images a lot in motion pictures where the use of a thick filter is part of the process of making the c...

Hi Ken... thanks very much for this... right... that settles it... the UV filter has to go... will get spares of the NDs instead to swap in and out... Thanks again for your help... Best

what am I doing wrong - Vingnette
I'll try that next Alan although I have been led to believe it's best to shoot in raw. I've only had this camera 5 mins and one of the lenses the (17-70mm) but am slightly disappointed in both up to now. I don't use the 55-300mm much but images with that improved when using it with no uv filter. ...

what am I doing wrong - Vingnette
Hi Stan The Pentax 17-70 is terrible for vignetting with a 85mm filter holder such as the Cokin P type. I experienced the same with mine, it's even worse than the DA 12-24. One possible solution is to cut the filter holder down so it only has two slots, this is easy to do with a mini hacksaw an...

what am I doing wrong - Vingnette
The vignetting on the two samples supplied look identical to me, which leads me to think it's a post-processing issue. In camera, there is a digital filter setting > Custom filter > Shading Level. If this is set to a negative figure you will get black vignetting. A positive number gives white vig...

The Pentax 17-70 is terrible for vignetting with a 85mm filter holder such as the Cokin P type I understand that David and had already said I wasn't surprised at 17 to 20mm, but, it doesn't explain the same degree of vignette with the holder and filters not being used. Also there was the same vignet...

Camera custom filter settings don't affect raw files, other than perhaps in PDCU if you request it to. John K

The Front / Back Focus Debate
Advice? There are some excellent wide angle exponents on here, I'm not one of them :D I carried it about a lot but rarely used it. A 77mm CPL polarizing filter is not cheap. And apparently you get weird results at wide angles. Carry a tripod with you, I was using it on a K-7 and needed a b...

Have I got a problem with my Sigma 10-20mm
In reply to David, yes, there is a filter on, but it makes no difference on or off. Fletcher and John, thanks for commenting. I think I need to try the same photograph using a different lens.

Pentax-F 70-210 focus problem
I just can't see the 3 screws referred to. Normally they live underneath the rubber focus ring ;) It's been a long time since I had the F70-210, but the images of the FA80-320 may prove helpful: http://www.photon.me.uk/pu/pentax_fa80_320/index.html Look at the last image particularly - there's...

Has the OP tried some shots without the UV filter, yet? ' Not yet, i'm hoping to take some tomorrow, unfortunately i don't have my tripod here but i'll try using some kind of support. I'll post the results here. I'll use no in-camera adjustments at all, shoot RAW, no 'Shake Reduction' and no...
