infra red conversion of istD
It is possible to have a camera converted to take IR. The IR filter is removed and substituted with plain glass (hopefully coated to prevent reflections). Then the only thing to remember is to correct the lens focus point. Older lenses with IR focusing marks are very useful in this respect. This ...

Close up lenses vs. Extension tubes vs macro lens
Nothing wrong with screw on close-up lenses, they're quick and as convenient as changing a filter and you don't lose any lens functionality. There's no reason to suppose that the close-up lenses (by top manufacturers) are of a lower quality than the lens they're being fitted to and it is possible...

how waterproof is the k10d?
I had my K10D out in the snow with temps of -8c. All was fine. I was shooting waterfalls. My buddy wanted a pick standing under it. So of course I abliged. It was very misty, had to keep the camera pointed down to keep the lens clean. After I took 2 shots the filter on my lens was covered in ICE!!!!...

Dust removal
Dust will adhere to the glass filter which covers the actual sensor for mainly one of two reasons. 1) Static, this should be easily cleared by the cameras dust removal system. 2) Sticky dust will be less easily removed by the cameras dust removal system. So, think about the environments where you...

Just about to buy the K10D plus choice of 2 lenses HELP !
The 16-45mm has a max aperture of f4 and a filter size of 67mm. The 16-50mm's max aperture is f2.8 so the filter size is almost certainly larger, maybe 72 or even 77mm. The latter will also be a heavier lens (note the spelling Pete, no 'e' on the end of lens :) ) due in part to the higher volume...

The Most amazing photos ive seen taken with the K10d WOOOOW
The kid does look jaundiced, so thats maybe two of us with dodgy monitors :shock: however he does look to be of middle eastern origin so the flesh tone could be accurate. The catchlight in the eyes looks a bit wierd, looks like a starburst filter?

Hotshoe problem
Every wireless trigger, and infra-red trigger I've ever seen works off the hot shoe, mine also have pc cables, but since these are relatively modern devices I cant imagine any manufacturer making cable only ones and the camera doesn't 'communicate' via the sync cable. There is no delay with infra-re...

Viewfinder, have you actually used a K10D? I use mine a lot, and I really am not seeing the mindless complexity which you love to vocalise about. With the sole exception of the "slimming" filter, I don't believe there is a single feature on it which I have not used in real life photogra...

I, too, am intrigued as to what this camera lacks that you desire. I have asked you before on a different thread, but you didn't reply. You keep mentioning 'mindless complexity', but give no example, other than the slimming filter which, I agree, is not worth the menu space. Dan

There are some odd features on cameras that it takes some thinking about to decide why they are there. I agree the slimming filter is one. The other is on my A20 and is a "Food" setting. To help me take appetising pictures of food... My Pentax A20 can't even boil an egg.

Where will Pentax be in Two Years Time?
I think that the K20D will have the same shape as K10D but will be covered in soft, tactile polyvynyl coating which moulds itself to the users hand. This will be avialable in a range of colours, the pink will be particularly popular. The camera will have vastly more modes than the simple k10,......

Portrait shots with natural light Advice needed please
Pete, As Rodger mentioned, you can adjust the colour temperature very easily if you've shot RAW and are using Silkypix. You can try manually setting the temperature, or use the "Skin sampler" in Silkypix to set the WB. Even better - take a test shot holding a white piece of paper and use...

Portrait shots with natural light Advice needed please
Peter (Mannesty), I wouldn't say the "all of your problems" disappear with an Expodisc :P You've got another thing to learn to use (and it can be used wrongly) ;) And with mixed and complex lighting it's still often easier to use the reflected method. But yes, the Expodisc is a nice tool...

Portrait shots with natural light Advice needed please
LOL! I have the 67mm too. I just hold it over the 12-24. HINT: If you want a really, really cheap way of getting incidental WB then Lee filters do a three pack of white translucent caps for £3 from Speedgraphic ;) They are huge and will fit anything (they are supposed to clip over the Lee filter ...

Portrait shots with natural light Advice needed please
I am interested in the discussion of the ExpoDisk I have seen these advertised and intrigued...... I have an old Video Camera (shoulder mounted JVC type - remember them!) that came with a large filter that you placed over the lens to set the White Balance. I assume this will also work with a came...

Quick question about a skylight (1B) filter
Pete, you have a 50mm lens, not 55mm, pay attention :D For a portrait shot I doubt you need the skylight (warming) filter. Leave it off.
