[michael_przewrocki2]

<p>What are technical data of old Apo Ronar 480/9? its 1200g<br>

rear-lens-munt seems 72mm but standard .75 pitch does not match. cannot screw in testadapter as much as it should.<br>

No filter-thread. </p>

<p>There's a few genuine experts on old lenses here, and I'd wait to see what they say, but I'll suggest if it isn't 0.75 pitch it's likely 1.0mm pitch.</p>

<p>You should be able to measure the thread pitch easily. Using a good millimeter rule, measure the breadth across <em>n</em> threads, and divide that measurement by <em>n</em>.<em><br /></em></p>

<p>I have an old brochure with technical data for Apo-Ronars, but it's for lenses in shutter (#3 for a 480mm). Yours sounds like it's in barrel mount.</p>

<p>Its M72 x 1. exactly.<br>

I do now understand it. Thanks.<br>

I was a bit confused since the seller did not send me the right depth gauge, different description which i oversaw.<br>

i will get now one with 0.5, 0.75, 1 steps.</p>
