Hello:
<p>
<p>
I would like to upgrade by lens to make sharp 20x24 enlargements. My budget is $50-80, and my requirements are a 6-element lens in very good condition optically (definitely no smudges or cleaning marks). It has to be 80 (preferable) to 105 mm focal length. Here are the examples:<p>
<p>
Beseler Pro 90mm<p>
Fujinon 90mm EP or EX<p>
El Nikkor 80mm f/5.6 N or 105mm<p>
Rodenstock Rodagon 80mm f/4 or 90mm<p>
Schnider Componon 90mm or 100mm<p>
<p>
If it is not a M39 (Leica) mount lens, I would also need a 4x4" lens board with mounting hardware for it.

Thank you for reading.
