Elmar 50/2.8 aperture question

[kermaier]

I have a vintage Elmar 50/2.8 in M-mount, whose aperture ring can move past f/16 far enough to be f/32 (according to my in-camera meter). Is that normal for this lens?
Thanks,

Where does it get to at the other end of the scale?

Can't say about the 2.8 M lens, but it is certainly true with my LTM 3.5/50 Elmar. There is at least a full stop available beyond the marked limit.

At the wide-open end? It stops solid at the f/2.8 marker. (I wouldn't expect there'd be physical room to open up wider than the nominal maximum.)

I must agree, sadly, that no lens's aperture can open wider than wide open. I've had three Leitz lenses, though, in which the aperture ring could be turned beyond the mark of the largest stop. In those, the smallest marked stop could not be reached at the other end of the scale.

That's something a lens technician can easily fix -- that happens when someone disassembles the lens and does not take care to mark alignment of aperture ring and lens barrel before removing parts.

I have an early M-mount 50mm Elmar that does the same.
