I picked up a nickel LTM 50/3.5 Heliar because I prefer it to the M-mount version currently in production. The LTM is collapsible, which I like for size convenience, it has aperture click stops, and its aperture and focus rings rotate separately.
Now I'm looking at the 50/2 Heliar Classic and I was favoring the M-mount collapsible version, even if it's not a huge size difference. However, the M-mount version has 11 aperture blades, while
the CameraQuest shop listing for the nickel LTM 50/2 says it has 10. Can anyone verify that? I think I'd prefer the defined sunstars of 10 aperture blades rather than 22-pointed stars from the M-mount Heliar.
