Originally posted by Yamanobori Personally, the MP count is just not very interesting to me. Sensor size, ISO, and DR are more important, with sensor size being the most interesting
I would have bought the 645D when it first came out if it was 40MP and a larger sensor even if the price was around 15k. Or if the wide zoom in the roadmap was available from the start. People can sit there and scream just stitch pictures all they want but there are times when you just can't. Back then when I was in the USA I was taking a lot of pictures with water in them, I love water, (ocean, waterfalls, streams, etc.). And high elevation mountain scenes, scenes with a lot of upper elevation wind moving the clouds rapidly. That isn't easy to stitch. And then there are these people that scream zoom with your feet... But then balancing the foreground you wanted with the background is harder. Stitching isn't straight forward when the fore ground is a meter in from of you and the background is 20 km in front of you
Now I am here in Namibia building up my desert landscape portfolio. Stitching is a bit easier proposition but isn't as necessary because the wide angle isn't used as much. But there are trade offs with everything, the larger sensor means less DOF which is not an advantage to me unless I decide to find a hartblei 45mm tilt/shift.
Anyways I made the call to go 645D, I haven't quite finalized the purchase yet. But I am not calling it off just because Nikon has figured out how to pull too much resolution from a 35mm lens. I know the D800 and 35mm lenses aren't going to perform to my expectations 75% of the time. Would the Nikon body and 14-24mm lens with a adapter to use 645 lens be a nice supplement and come in at the same cost as just purchasing the 25mm 645 lens, sure. It would be a great back up and super wide angle supplement. An option I may go for. I will likely wait and see what this new wide zoom is for 645. If this new lens performs and comes in around 3-5k it is a no brainer.
Most photographers if they can justify it will choose the 645 medium format over the D800. I think the 645D II will have a larger sensor for sure. The current 645D will likely be starting at 7k by then making the entry into medium format more viable. Will it be a 67D, no, not a chance. We will likely never see that. I don't want higher MP; I want dynamic range, wider angles, and good high ISO (generally means keeping MP count low). Good high ISO lets me stop down more to get DOF and still use a reasonable shutter speed. Stopping down to 22 is going to reduce the lens sharpness making 60MP less of an advantage over 40...
