Get Hasselblad medium format at B&H Photo.
I’m noting highly satisfactory results with long exposures on the Hasselblad H6D-100C. Sub-freezing temperatures help, but the results still seem unusually good particularly since long exposure noise reduction is not used, a huge time savings.
It’s not just the exposure itself at a whopping 100 megapixels—it is the ability to push an exposure, boost shadows, increase or reduce luminosity by color (e.g., blue sky) without the horrific edge artifacts that prevent me from doing so with (for example) the pre-cooked raw files of the Sony A7R III. It’s an entirely different ballgame, and it’s going to be hard to go back to ordinary.
This page is in progress, with more commentary and discussion to follow, and a few more images too.
Includes images up to full 100 megapixel resolution along with RawDigger histograms.
