Thanks Mark, will try, but his Ebay advertisement specifically excludes the United States for some reason?

Cheers,

Surprisingly good! Here's a dropbox link to a jpeg (the TIFF is twice as good): Dropbox - Samyang 24 non-TS equivalent to c15mm CF006109.jpg

By the way, the effective pixel count of the P65+ is 60.5MP's.

Thks again - btw whats the Phase One flange distance? Thks, Ian

You can find all flange distances on Wikipedia under camera flange distance. It is the same as Mamiya 645 mount.

The converted lens is quite hard to focus as there's not much room to play with. The P65+ doesn't have Live View so that makes it harder. The lens is definitely a keeper and will be even easier to use when I eventually get my hands on an IQ-range Phase One back with Live View.

I'm curious how this might work on a Mamiya 645 Pro film body. I assume there's no aperture connection between the lens and camera - does it stop-down when on the camera?

I'm embarrassingly new to using manual focus lenses but what I do is focus with the lens wide open (f3.5) using the focus indicator aid < o > in the viewfinder (until I hear the beep indicator), I then change the aperture to f11 or f16 and take my photo. The screen on the P65+ is REALLY bad so I tend to look at the histogram to check the exposure (which I'm really bad at nailing!). I haven't taken the time to learn hyperfocal focussing; I should really.

The little Samyang (which I've affectionately named Sammy) is sharper than my VERY good copy of the Phase One 28mm f4.5 AF Aspherical!! It's just a shame that it's not autofocus, but that's not the fault of the lens.

Yes you should. But: the higher your resolution, the more you have to be careful about hyperfocal focusing. Back in the day, film hid a lot of things that now we can much more easily see, such as diffraction. That said, I do it all the time, pretty crucial for more than 90% of what I do. I just don't have my old misguided expectations about acute sharpness that I once did for things out of the true focus band.
