<p>This was in a bunch of 8x10 Deardorff stuff. Looking for a name or accurate description of what it is called. One knob opens and closes the aperture, the other one locks it.<br>

Thanks<br>

<p>hi steve</p>

<p>in addition to what bob said ...<br>

it is a universal mount ( the locking iris ) that allows barrel lenses<br>

and other things that might not necessarily be on a lens board that you might have .. to be mounted<br>

on the camera. lots of people use + love these things, it makes using un-boarded lenses &c<br>

easy to pick up and use. probably a loose mount ( iris not snug/locked well to the barrel) would make<br>

the lens sag, attaching a long lens too close to the back end would not be very good, but i would not hesitate<br>

to use one of these even for "serious work" if i knew its limitations ... i've always wanted one<br>

since i tend to use a lot of barrel and home made lenses with a quck+dirty masonite/card stock/matboard<br>

or foam core lens board or friction mounts ( even for serious work ) .. i never have the $$ for a<br>

universal iris mount, which depending on its size is between 100-250$ .. ( or more )</p>

<p>one's currently being sold on another photography-space for more than<br>

i suggested they were worth :)</p>

<p>as i said, some people love these things, and there always seem to be people buying them<br>

( and they don't seem to be the person who just bought one, tried it, said "ugh, why did i buy this?!" and then re-sell it. ) </p>
