Dear Harklee
Your fore ground gravel etc. looks sharp. What looks out are the sea stacks and back ground. It appears that you're too front focused or that's what the AF did. I think that you would be better served, as would potential 645D purchasers, if you picked an easy, bland and boring subject that gave you hard data about the camera and lens performance. For instance, I live at Crowley Lake at 7,200 feet on the east side of the Sierra Nevada. The fall colors are going off against a foot of new snow. Diaphanous clouds are rolling across the mountains creating beautiful dappled light. But if I had just received the 645D and lens I'd be shooting pictures of the side of my house trying to know for certain that the sensor was aligned, that the camera focused repeatedly on the exact same spot at all focal lengths, that corner to corner sharpness was achieved at a certain f stop and I'd make damn sure that infinity focus indeed focused on infinity. I don't care what f stop I stopped down to. Diffraction doesn't matter in a big print. I've never seen it and I used f 32 and 45 plenty. If you need f22 you need f22. Who wants a blurry image. And you bought the 645D to make big prints, right? I only used a 4x5 because I wanted to print to 32"x 40". Otherwise I would have used a 35mm camera.
Do a sample, no jpegs, of a subject 4-6 feet away from the camera. Who cares about bokeh. When was the last time you saw an Ansel Adams image with bokeh. A bush of some sort will work well. You can look at how detail is rendered in a very difficult depth of field situation. Then do the side of a building at 30 foot distance, or a tree, or rock wall. Check corner to corner sharpness. Then check infinity focus. A mountaintop, the moon, distant buildings are good. Infinity focus is VERY important and it should not be assumed that when a lens is turned to infinity that that is where it is focused!! Lenses with infinity stops are REALLY useful.
The goal is to prove the camera and lens and sensor can do what you want them to. Craft first, and that includes equipment, then unfettered expression and creativity can follow.
I look forward to seeing meaningful tests that prove the 645D is what we hope it to be.
