cleaning
What about a vacuum cleaner? Obviously set to its lowest power setting and using the smallest attachment piece. Remove lens. switch on hoover and place somewhere near the lens opening for a few seconds. Wouldn't that get rid of all the rubbish, without damaging the camera - obviously you don'...

cleaning
It'd probably work but I don't recall reading this as a recommended method. Also, there is probably more 'blowing' power at close range out of a purpose made blower like a Giottos Rocket than a vacuum cleaner can 'suck' from a distance. A combination of the two might be ideal. Get the dust airbor...

cleaning
Unfortunately, no amount of blowing can shift particles from behind the screen, so it has to be removed. The penta-prism (or in my case mirror) housing is sealed by the screen itself - but obviously not completely. I was quite pleased with my efforts, no visible particles and the hair had gone but ...

http://www.green-cleanusa.com/home.html Kimbo, In the morning a camera shop will clean my focussing screen and mirror using this. If it as easy and good as they say I will buy the travel kit.

cleaning
Ok, I’m going to use this thread to share my experience with sensor cleaning products. I’m using 2 products which, as far as I know, are the most widely accepted nowadays: - SensorBrush (or the homemade version: http://www.prime-junta.net/pont/How_to/a_Brush_Your_Sensor/a_Brush_Your_Sensor.html) -...

Yes this is why I am attracted to the Green-clean I mentioned above, even though it comes with wipes in the full package, I would be very wary of doing that myself.

Getting to Grips with RAW
Quite agree with George ;) The in-camera JPG comes from the RAW file anyway - the camera just throws away the RAW data. As I've mentioned many times before, it takes time to get to grips with RAW conversion. To be honest, it's a bit like comparing high-street film processors to hand-develop...

Getting to Grips with RAW
The trouble is, both sides of this discussion have no idea what the terms of reference and abilities of the other side are. I don't dispute that the RAW capture will enable crisper, sharper results, and as Matt says above we also agree that there is no more resolution as such in the RAW capture, as ...

can we trust review sites?
The reason I am asking this is because after playing a couple of weeks now with my new DS I am very happy with the unit. If I read reviews/tests on the so called professional review sites they compare everything with the Canon D350 and the Nikon D50 and D70 as being the holy grail of affordable D...

can we trust review sites?
I.... ah.... got enamoured with Pentax when I was a kid. Their cameras were regarded as the best and only a selected few could afford them. Seeing a red Pentax logo on a camera strap was sure to earn appreciation from everybody. I dreamed with a Pentax while I struggled along with my father's Zenit ...

Pentax istDs Focussing screen
Blurred and blotchy does not sound like scratched and damaged. Maybe try cleaning it again. Here's my advice: use a micro fibre cloth, and Pledge furniture polish. Sounds crazy and dangerous? yep. but what've you got to lose? It's already ruined right? ps; I've used pledge successfully on my moto...

*istD banding
Another question to ask is: has this always happened? Not sure - but suspect it has. I remember a few shots taken several months ago where I think banding occurred. A thought - re another thread and batteries/ battery grip etc and the use of Ni-MH batteries - could it be a low voltage problem cau...

news on the 645D about crop?
This isn't confirmed... just a hunch... The 645D sensor will not be full size. It'll be larger than 35mm, but I can't imagine it'll be full size. You've only got to check out the prices for the Phase One backs and you'll understand why. Additionally, the marketing material for the 645D specif...

news on the 645D about crop?
Knew I'd seen it somewhere... http://www.dpreview.com/news/0503/05031603kodakkaf18000.asp If this is the sensor, then it has a 1.3x FOV crop - 45mm x 35mm. That, as the Pentax press release says is "extra-large" (but note: not full frame). But note that the sensor size is guess at, bas...

news on the 645D about crop?
Ken has some really strong opinions, but a lot of them are just hilarious. Why do you have 11 AF points when all you need is 1? Why do you need 77 segment metering when all you need is one? Someone needs to call for a whaaaambulance. Philip, he has compared one brand to another. He has quoted fact w...

news on the 645D about crop?
I shoot all my APS C DSLR's using only the centre focus point so I do only need one AF point. I generally use centre weighted and spot metering as well. Do you complain that your DSLR has 10 extra AF points you never use? Do you complain that your camera has matrix and centre weighted metering? T...

news on the 645D about crop?
No complaints about extra AF and metering points Philip, same as I don't complain about having video on my K7, which has yet to be used. I agree with the Dx statement as the other brands of MF use the Kodak KAF3900 sensor that is 50.7mm x 39mm, the Pentax uses 44mm x 33mm. It is a cropped sensor....

according to that then, if it's a Kodak sensor it's probably this one http://www.kodak.com/global/plugins/acrobat/en/business/ISS/productsummary/FullFrame/KAF-40000ProductSummary.pdf

likewise. Leica seem to think there's a market for a larger than 35mm SLR, their S series has a similar size sensor. Of course Leica never go for large markets anyway but it will be interesting to see what happens.
