I currently have the 150mm lens as my longest lens for my Phase One 645D camera. I need to use a longer lens at times, but it seems that the 240LS lens Phase advertised is a not going to be delivered for a long time. What are the best options currently for a lens in the 200-250mm range? I have been looking at the Mamiya 210mm f4 lens, but have been told by one user they were just a bit disappointed with the image quality.
I also heard that with an adapter, Hasselblad lenses can be used. Ideas?
