Frank, how did you get the front lens unit off? I have a Voigtländer Rollfilm with a 11.4cm f/4.5 Anastigmat Skopar, and I couldn't get it off with my fingers. Looks like I'll need a flexiclamp.

Thanks for the diagnosis. It's good to know I don't have to buy any spare parts.

No, I can't focus manually to infinity. I was checking the focus on a digital body by checking live view, and the farthest it focuses is 3ft. I'm going to try fixing it myself because it's so cheap, so thanks for that link!

I picked up this lens for a song and now I know why: it won't focus to infinity. At most I can focus on objects about 3 feet away, but the distance scale is completely off and says that it's focused at about 8-9 feet. Objects at infinity are totally blurry. Does anyone know how to adjust focus on this lens? It's one of the earliest EF lenses and makes for a great "adjustable prime"/"adjustable normal" lens for bright light, as Mike Johnston calls lenses with narrow zoom ranges. I was reading this blog post by Roger Cicala today that says that Canon EF lenses are adjusted for infinity focus solely by the thickness of the mount, unlike Nikon lenses which use shims. He writes, "Canon bayonet mounts come in various thicknesses, so rather than shimming they simply choose the correct thickness mount when they assemble the lens." Does that mean I have to buy a replacement mount that is thinner than the one I have? I checked the auction site and they don't sell mounts by different thicknesses, so I'm not sure what's going on.

<p>Just checking back in. I ended up getting that Sunwayfoto plate. It fits flush with the front edge of the Hasselblad plate (when you put the strap loop thing toward the front, which is a lucky coincidence), and there's a little bit of margin on the other three sides. Thanks for the recommendation, Will!</p>

<p>Has anyone already found which Arca Swiss plate fits onto the Hasselblad Tripod Quick Coupling plate? The bottom looks like this if you haven't seen it:</p> <p><img src="https://www.wide-angle.nl/wp-content/uploads/2016/02/1316339.jpg" alt="" width="600" /></p>

Is it "stuck" if I can turn the ring around and around with a friction tool? It looks like it's spinning in place, neither loosening nor tightening.

I have to clean the aperture blades, too, but my 100/2.8 FDn doesn't have a little hole in the front. How do I get the front nameplate off? I've been turning it forever with a friction tool, and although it turns it won't come off. I've tried both clockwise and counter-clockwise. Stuck at step 1!
