Artifacts on images
If you are seeing grey blobs in the same place on various images, it's almost certainly dust on the sensor. A rocket blower should get rid of all but the most sticky dust (probably pollen). When it becomes necessary, which is very rarely, I use an Arctic Butterfly brush from Visible Dust. One ...

Is 300mm much better that 200mm?
The SMC-FA 80-320 is a fine lens and can be had quite cheaply. However, the SMC-DA 55-300 is apparently sharper, and more compact (because it's for digital). and a person who has outsold the Bible knows a thing or two. Huh?! Estimated Bible distribution to date stands at an estimated 7.5 billio...

cleaning sensor with a gittos rocket
Hi I have a 200d which had rather a lot of dust on my images. I was told to get the rocket and tried it out tonight. It seems to have got rid of a lot of the big dust deposits, there is now lots of small bits clumped at the bottom when I take any image of the sensor. However, now when I look t...

cleaning sensor with a gittos rocket
What you have probably done is blasted the rubbish up inside the viewfinder!.........I did that with my DS and have never used a blower since.......

cleaning sensor with a gittos rocket
You will have to remove the focussing screen and give a blow with your rocket blower. Just be careful and DON'T touch it with your fingers. Heres a guide on how to remove it.

cleaning sensor with a gittos rocket
Hi However, now when I look through the viewfinder the screen is absolutely clarted up with fibres an I cant see how to get rid of it. It is a real pain, any ideas please. Cheers It might be a pain, however that is where it stops! It does not impact on images and you get used to a certain am...

cleaning sensor with a gittos rocket
Thanks for the advice guys and the link, not sure my clumsy hands are up to that though, perhaps I will put up with it until I can find a nimble fingered helper, or a gynacologist!

cleaning sensor with a gittos rocket
There is a special pair of spring-loaded tweezers that makes it easy. These are supplied with replacement Pentax focusing screens. It might not be a bad idea to have a spare screen! This video shows you how to change it: http://uk.youtube.com/watch?v=YqZCjT-jr1s It's generaly not advisable to...

Polarising filter
Also do get a CIRCULAR polariser not a linear polariser as I believe the latter interferes with the auto focusing Sorry if I've passed on bad information, but it's what I've been told. May-be other Camera systems are effected but not Pentax, or its only if you happen to have the polariser ex...

K30D with an APS-H?
It's just a rumor that the K30D would have an APS-H 14.6mp CMOS Sensor with a 1.3x crop, but it's interesting one. They are cheaper than Full-Frame cameras but perform better than the APS-C cameras. The Canon EOS-1D Mark III & Mark II are the only one with an APS-H sensor so it isn’t really a ...

K30D with an APS-H?
There was a rumour before the K20D came out that IT would be an APS-H sensor too. :roll: I think we all just have to wait and see. Gives us something to look forward too in spring maybe. Or not if like me you have just got the K20D and can't afford another upgrade if upgrade it will be.

K30D with an APS-H?
It isn't, not for me that is. But if you own a lot of old quality glass (wide angles) you might want one. personally I like the Nikon D3 approach. Best of both worlds, in one camera. Martin. Someone told me that the D700 also does this but it drops to a 5mp output .. is this correct and is it the ...

K30D with an APS-H?
:lol::lol::lol: And we don't want that to happen,right? Would be a shame if Pentax got scr*w*d by some DA lenses and would lose it.:oops::wink: I'll guess you meant vignetting. But of course I could be seeing things also :D Martin. Yep Martin you're right, don't know what I was thinking :oops: ...

UV or Protector
I went through a similar discussion a few months back ... The general conclusion was yes, fit one and the Protector is enough as UV does not affect the sensor in the same way it affected film. Which ever you go for, choose a good quality one such as the Hoya Pro1D - they are being sold off as ...

Full Frame?
Hi, Does Pentax have a full frame sensor digital slr? If not do you think they will ever have one? Its just my dream is to have my own photography studio within the next 5yrs (once ive learned how to take photogtaphs , lol Matt

Full Frame?
Who knows?! They may have one in the works, then again they may not. I seem to remember reading somewhere that Samsung had built/designed one, so it might be that they use that. Or, maybe they could 'buy in' a Sony designed/built sensor similar to how Nikon have done with previous cameras, ...

Full Frame?
There have been rumours that Pentax are looking at an ASP-H sensor (1.3 crop over 35mm), these appear a bit stronger than thoes for a full frame. Anyway, with the advances in sensor technology and post capture processing in camera and on chip, I am not sure that there will be much advantage of a ...

Full Frame?
Absolutely. Many questions have been revisited time and time again and it would be most unreasonable to expect a new poster to check everything that had gone before, just in case it had already been covered. A forum is an area of flux, not a book that has to be written and then set in stone. Anyw...

Full Frame?
Does Pentax have a full frame sensor digital slr? The APS-C sensor is full frame as far as most of my modern lenses is concerned. I would have to invest in bigger (and longer) lenses if I switched to a camera with a larger sensor. I don't see the need anyway while the quality and power of APS-C s...
