Good points Douglas, but I guess for me as a pro, the lack of lenses and lack of rental support could be deal breakers. And no video is a real let down - I am just now starting to tinker with video, and there is no turning back. Video is being asked for by many clients these days...and it can be very lucrative.
Anyway, how are you liking the a900? I handled it a couple times and it seemed pretty nice. (the noise some people were getting off of that chip scared me out of buying it though.) Which is the best RAW converter for it?
Yeah, Lisa, the noise thing with the A900 is there, but overstated. About the same as 5dii at ISO 800, and starts loosing ground at ISO 1600 or so. Still, it's way better than many cameras before it at high ISO. Hilariously, I sometimes shoot at ISO 1600 on purpose, because I like the subtle grain, but my normal shooting never goes much above ISO 400-800, anyways. Video is quite a cool feature for the 5Dii, and I guess it really depends on what you shoot. My work requirements are pretty simple in that I only ever shoot a 24-70, 50mm and 85mm, and Sony is doing well in that regard. Their main weakness is t/s and long primes. As far as rentals, I have to know a little ahead of time to do it through the mail, but, like I said, I don't use a large number of lenses (product of medium format photography.) I guess if I had an emergency, I could just rent a Nikon or Canon body along with lenses in a pinch, but I haven't really ever been in that situation (or I could break out the Hasselblads and rent MFDB.)
As you can see, I'm probably a narrower market of intended users, and the A900 was a perfect fit for me, but the 5Dii, while not exactly being the best at some things (outside of video,) is very good at most things, and it sounds like the perfect fit for you. The A900, like the D700, is a little more specialized. I happily paid $3k for the A900, so the A850 seems like an outrageous price to me
As far as RAW converters, that is a huge subject on its own, but I use C1 Pro for large batches and Raw Therapee for smaller ones. C1 is great, but the color is a bit off in the A900 profile. RT is outstanding. Adobe really kills the A900, especially at high ISO.
Take care, Douglas
