Cleaning behind the focus screen.
Like an idiot I purchased a split focus screen for my K10D to aid manual focus macro stuff and it was basically a load of rubbish so I put back the original. I now have half a ton of dust behind the screen and a ruddy great fingerprint on the screen itself (sigh). So anyway, I am going to buy my...

Cleaning behind the focus screen.
The Arctic Butterfly is designed for sensors, but is actually good for the focusing screen and prism as well. An ordinary camera brush might be enough, though. Katzeye make excellent screens for manual focusing.

Cleaning behind the focus screen.
Hi, Cleaning behind the focus screen is realy easy... (although when I had dirt behind the focus screen of my DS it took some time for me to suss how to do it) You already know how to take the screen out so just pop it out and blow with our blower. While its outs out use some sensor cleaning s...

Cleaning behind the focus screen.
I sent an email to Pentax UK and they quoted me a price of £25 plus return postage and VAT to clean it. I thought that was quite reasonable actually.

Cleaning behind the focus screen.
Hi I don't agree - I think £25 + postage is a lot for what is likely to take you just a few minutes given that you know how to remove and replace the focus screen, you already have a rocket blower, and you have a brush on the way AND you aleady intend to buy a new screen what can you lose by ...

Cleaning behind the focus screen.
It may be reasonable for Pentax to charge £25, but I agree with Mr Bob that it's not worth it when you can DIY. Total postage would cost over a tenner, and you'll be without the camera for a while.

Cleaning behind the focus screen.
you really have no idea how bad the dust really is do you, when I say bad, I mean BAD as in dust and little black hairs right in all corners of the viewfinder where I have pushed it while trying to clean. I will wait for my brush to arrive first though, just to see if it can do a reasonable job.

White dots over K20d pics!
Hi all, I purchased a K20d about 2 weeks ago now and have enjoyed using it for a variety of location photography. I have now come to process lots of images and noticed that every single one regardless of the lens, settings, iso and pc software all have little white specs over the shots. Of cou...

White dots over K20d pics!
It's certainly not dust. Dust on the sensor would appear as dark dots or blobs, and dust on/in the lens would be out-of-focus. Could be a hot pixel problem. Apparently there is indeed a bug in the firmware, and there will be, or is, a firmware update. See http://www.google.co.uk/search?hl=en...

Which extra bits to buy?
Hi Rob, welcome to the forum :) You've mentioned most. For me it was: Spare battery Spare memory cards (SanDisk Extreme. For the K20D I'd recommend the 4GB SDHC cards as they fill up quickly otherwise if you decide to shoot raw) Memory card reader if you need one Lens cleaning cloths Rocke...

Which extra bits to buy?
Hi Rob, welcome to the forum! Apart from the obvious (memory cards, batteries, cleaning items), I would recommend that you order the body with the kit lens first, use it for a while, then, when you know what kind of subjects you like to shoot, start looking then. Before making any purchase, do...

pentax k10 samsung gx 10
In hindsight it would have made sense to wait for the K10D to come and go, and just get the K20 after they've fixed problems, and also upgraded the components. For me it's not such a hard decision as I don't have the money to upgrade and the GX10 is my first SLR so still got a lot to learn yet. Howe...

K10D - underexposed images
Yesterday I finally saw the 'blown highlights' warning - the corresponding parts of the image (sky at sundown) flashing red. I also understood one more thing: if there is a big difference in exposure values for different parts of the image (sky at sundown at 1/640s and dark trees at 1/50s both w...

K10D - underexposed images
You'll find that film (slide and print) generally has a larger dynamic range than any digital sensor currently on the market, however, digital technology is still comparatively new so don't be suprised if this situation is reversed in the near future. We may not be there yet, but I bet there's a sc...

K10D - underexposed images
I don't remember having similar problems with slides... do they have higher dynamic range that k10's sensor The dynamic range is about the same... however, film does not fully saturate as you approach the highlights. In contrast, the CCD being basically linear in response, will hit the blown highlig...

faulty camera or lens - please help? - and dust in the lens!
It sounds like there's a connection problem between the Tamron and the body - try cleaning the electrical contacts on the bayonet and see if that improves things.

pentax k10 shooting modes
regarding your comment about the white piece of paper would this be a good idea to check for dust on the sensor .I used to do this with the canon then view the piece of paper enlarged on a pc and the dust particles would show quite easily not that i have had any dust problems but the canon was a bit...
