I have searched but have not seen many people using this for weddings. Most lean toward the 5D/D300. (for entry level bodies) I read the low light capabilities on the D300 is impressive. I'm thinking dollar for dollar the K10D would be a fine wedding camera. The only drawback being low light (no flash in church)...but it has in camera SR. With a fast prime and SR, I wonder if ISO 400/800 would suffice in most situations? I also read the AF is not as fast. Are these things one can work with, considering the price? 2 bodies can be bought for the price of one 5D. I keep thinking my wedding photographer (11 years ago) used manual focus meduim format,as did most I assume. He managed to muddle through... I'm not thinking of doing this for a living, but I was looking to upgrade my Pentax DL and it occured to me there was not many wedding photographers using this camera.
