Photography: Camera sensor size difference

sorry if this is taking the level of conversation down a bit, but any of you have experience with pentax's dslrs? i'm considering upgrading and the k20d looks quite good from reviews/specs, but i've never used a pentax dslr (though always used a k1000 for film).

thanks

it's a very nice camera, get it mate, unless you're buying it in order to use your old pentax lens, then you might get caught short due to the crop sensor (my father did, end up getting a 30mm F/1.4 sigma to replace the nice Pentax 50mm F/1.4).

$270 for the adaptor ring to put Nikon's on a Canon body? Fuck that.

£99, not really, you can get a nice 50mm F/1.2 for about £120*, add the adaptor, £219 and bingo, still a lots cheaper than a brand new Nikon 50mm F/1.2 that sell for £700.

or get the Canon equation that sell for a staggering £1200, now £99 look promising.

*that if you look carefully, you can do a BIN for £250 on the bay.

that is only really an issue if it prevents you from handing something to your client that you are not happy with or the the piece of equipment is overpriced compared to the competition.
any other issues are for forum fanboys with a flickr account to discuss.

ahh music to my ear.
