Print Size With Pentax 645Z

What we have here is normal sharpening in Lightroom, and additional sharpening in Photoshop, .6, 312, 0, 0 and we can see sharpening artifacts at 100% but this makes a very nice print at 41X75 inches (150 dpi), this from a two image stitch.

I don't know that I'm getting any more resolution with the Pentax compared to the Nikon D800e, what I can say is that I get it consistently which I didn't with the Nikon - everything had to be ideal - now I just fire away and can reasonably assume I'm going to get great results. This may not seem right, that  somehow I'm compensating for poor technique with more expensive equipment, but what I see happening is that with the Nikon, I could not always control every factor, and now I don't need to. Welcome to the real world of less than perfect lenses, less than absolutely still tripod and camera, and no wind, and , yes; absolutely perfect technique.

It reminds me of the days of trying for absolutely highest resolution with 35 mm. film, we'd shoot with high contrast copy film, processed in a compensating developer, and use only the best lenses in camera and under the enlarger, and yes, the results were sharp, though not always, and more often than not the prints were crap because the tools only really worked for a very limited selection of subjects and soft lighting. Switching to medium format produced images of a rich tonality across a variety of subjects and conditions that could not be reproduced in 35 mm.

The Pentax 645z is simply more reliable than smaller cameras when it comes to quality large images, and that's important to me.
