80B Filter on a DSLR
But surely, once you adjusted your piece of paper once, it's useless. Ah, but I had a thought, a piece of paper has two sides doesn't it so you could use the other side if you wanted a cooler effect. Damn, now it really is useless for white balance. There's a job here for Don after all, we ne...

all those old Zenit lenses
Also got a broken Lubitel here, Do you have the filters for it? I have a pristine working lubitel 2 that I use, but the filters are missing. Would be nice to get some. Mine is a 166U which has a standard filter thread on the taking lens. I know the ones you mean though, I seem to remember the Lubit...

External hard drive recommendation please...
I need to buy an external drive to back up my mac and photos. been looking at these Lacie drives... Why that one and why Jigsaw? Does your Mac have enough USB power to run that on one port? I get the impression you are buying on price. Otherwise I would suggest 250GB might be a bit small f...

Converging verticals.
Distortion? What distortion? Do you mean barrel or pincushion? They are none. Unfortunately no one makes a shift lens for Pentax DSLRS. I have the 28mm f3.5 shift which is a fabulous big expensive piece of glass which needs to be used on a tripod with spirit levels and a grid focusing screen, you...

Photos in the snow
Snow relects the sky so can look too blue. 81A filter or set AWB to Cloudy. All that white affects metering so shots may be too dark. + exposure compensation. Keep batteries warm. Have a great time! :)

Photos in the snow
Keep your camera at above freezing if you can. Make sure you can keep your battery/batteries, including a spare one/set, warm. At those temperatures, they'll not last long, if the camera functions at all. Take a circular (rather than linear) polarizing filter with you, and use it. Dial in a...

Photos in the snow
I hope you are a very good skier if you plan on taking your tripod on the slopes. You just need one fall to break that shiny new tripod or (worse) a leg (yours, not the tripod:wink:). A polarizing filter can also be put to good use to cut reflections on the snow and improve contrast. It will even...

Cokin P Filters
I have a set of Cokin P filters. The Cokin site says that they are suitable for focal lengths from 28mm. I am about to take delivery of a Pentax 16-45 :D which is a 35mm equivalent of 24mm at the wide end. Does anyone have any experience of P filter system and this (or similar focal length lenses)? ...

Cokin P Filters
I have not had any problem using my P filters on the 18mm Kit lens. The main limiter that I am aware of is the size of the filter thread.

Cokin P Filters
Hi I use Cokin P size filters on a DA*16-50 which has a thread size of 77mm against the the thread size of 67mm on the DA16-45. With my lens there is viginetting if I use a standard P holder, but there is a slim P holder (only takes one filter). I've emulated a slim holder by cutting 2 slots of...

Cokin P Filters
Just to re-iterate... The SMC-DA 16-45 (which has a 67mm filter) is perfectly fine with Cokin P filters ;) The SMC-DA 12-24 (which has a 72mm filter) can just about work with Cokin P filters if you use a wide angle, single filter holder (or, as I did, hack up a spare filter holder by cutting o...

Cokin P Filters
...The SMC-DA 12-24 (which has a 72mm filter)... *ahem* 77mm filter *ahem* I've been waiting 18 months to correct MM on one of his posts! :lol: :lol: And I use the "wide angle" Cokin P holder on the 12-24 and it works fine down to about 14mm with only very slight vignetting below.

*ahem* 77mm filter *ahem* I've been waiting 18 months to correct MM on one of his posts! PMSL! :lol: You're absolutely right... it's 77mm. (My excuse is that I'm not near a camera right now, and my forgettery isn't quite what it used to be :P ) Matt

Cokin P Filters
The SMC-DA 16-45 (which has a 67mm filter) is perfectly fine with Cokin P filters ;) Well, it is (in my experience) as long as when you're at 16mm you don't have the holder at an angle, otherwise it does vignette slightly in opposite corners. As long the holder is vertical or horizontal (I mean t...

K110D infrared conversion..
Have you already tried an R72 or similar IR filter? because I know my K100D had a weak IR filter. I was very happy of the Results with my Hoya R72 screw on filter, though I did have to resort to using a tripod to keep the ISO down and the aperture at an optimum setting. Other than that im of no r...

K110D infrared conversion..
I have read that removing the IR blocking stock hot filter and replacing it with an IR filter will get me hand held shutter speeds only slightly slower than visible light speeds without the need to have the lens wide open and having to shoot at high ISO. I have tried IR with my GX20 but it sucks ...
