90 Elmar f4 Collapsible

[christopher_a._junker1]

<p>This lens came to me mounted on an M3 that had been in a closet for 30+ years. Very stiff focusing, but the lens is clean. How does it compare to the previous Elmar 90 and for this lens, what is the correct lens hood? </p>

<p>I owned this lens for a few years. It has a coated lens whereas the previous one didn't, so optical performance is improved somewhat, with best performance, in my usage, at f11, although I usually used it at f8. My recollection is that the correct lens hood is 12575N, the same one used on the 2.8/90 and 4/135. The weakness of the lens, IMHO, is that when fully extended - due primarily to age, is that sometimes you get a little wobbly when locked into position.</p>

<p>Confirming hood # 12575; my current Makro Elmar came with that one and it does also fit on the old 135mm Elmar.<br>

AFAIK you shouldn't collapse your lens on a digital body and Leica don't give information about maybe possible simple updates like "just put a 5mm broad zip tie behind your lens head".</p>

<p>It's the same as the solid Elmar f4 90mm from 1954, optics bumped up a little by slight changes and coating from the 1930's Elmar. Glad it's clean. It's a bit heavy. Yes, same hood as for the 135 f4.5 Hektor M, 135 f4 Elmar M, etc.</p>

Look for haze behind the front element, very easily removed and cleaned.

 

One of my favorite lenses, use on the M9 and M Monochrom. Do not collapse it on a digital M.I find the uncoated 9cm F4

Elmar has too-low contrast for the M Monochrom.
