If the dust is able to get there, is there no way of getting it out or blowing it out or something?
Atleast Ive narrowed it down to the Nikon, the Canon or the Pentax
Any word on the different lenses, etc?
Serious is once again scaremongering.
Dust removal is a piece of piss. You use either a nice air brush (fine brush with a squeezy bulb), or you can use various other items like "sensorwands" (google it
).
Hell if you cant be arsed with all of that, just take it into a camera shop once every 6 months or so and get them to give it a go.
Dust only gets in there normally if you change lenses every 5 seconds, so professional photographer... yes... will end up cleaning the CCD every 6 to 8 weeks maybe more. Guy who has a 70-200 lens who just wanders around taking shots of landscapes, some "friend" shots, and is messing around with a camera, not so much.
1. he wont change lenses anywhere near as often
2. dust particles on the picture will only really bother him after it is reallly dusty
and in fact with a little photoshopping you can get away without cleaning it for aaaaaaggeesss.
Put things into perspective.
My mate bought a 350D over a year ago now I believe, hes not cleaned it once.
Oh... and after seeing the costs associated with owning a dSLR, I would go for the olympus, more bang for the buck. and lenses appear to be cheaper also.
Same mate above has paid more in lens costs than he has for his camera.
1 x 50 prime
1 x 30-85
1 x 70-300
1 x macro doohicky that I cant remember what the hell it was, think it was an F1.8 at least.
Add to that his slave flash unit system, his tripod, his cleaning kit that he has yet to use.
