Any information on Rodenstock Hemi-Anastigmat?

Between 210 and 240mm was my impression, too. But according to this catalogue page, the next longer one would be 300mm and that's definitely much longer than mine. One can also measure the diameter of the front/rear lens, which should be around 33mm for a no.2 (210mm) vs. 43mm for a no.3 (300mm).

The VM is wrong in this case, it really IS a 3-in-2. I have one too, and my books all agree with my lens. Cemented pair in front, single meniscus behind.

It's surprisingly good at small stops, and unsurprisingly not-so-good wide open.

Interesting. Now I want one.

Mine does say #2 on it - I just remembered

but I swear it's a bit longer than 210.....infact..I remember having to rack the rail out a bit more when I switched from my 210 to my Hemi (at infinity).. and add to the fact the lens is front mounted ...it has to be longer than 210

maybe I'll do a reasonable test this weekend to see for sure...

Okay..super wrong

I finally got around to making a semi reasonable comparison to a 210 lens and yup..it's about a 170 or 180 or so


Rodenstock Hemi-Anastigmat #2 is shorter than a 210!


now

I've heard -tell of a 300mm version

THIS I want

Whelp


my #4 (400mm) just showed up from Poland and it's pretty sweet

with a little electrical tape - I jammed it onto a sinar board although the thread size would fit inside my #4 compound or my #5 betax...if I get an adapter made
