Bob: Virtually any lens for any Exacta camera will fit it (it seems like toward the end they made some cameras using a different mount (M42?).. There were some aftermarket lenses made, too--Vivitar for one). I believe some of the Topcons used the Exacta mount, too. A nice lens for the Exacta is the Zeiss Jena Pancolar 50mm f/2 lens. On Exacta lenses the nearest thing to auto stop down diaphragms were lenses with a button built in that sat above the shutter release button on the camera. When you pressed the lens button it stopped down the lens, then tripped the shutter. There were also a number of preset lenses that you open up manually to focus, then have to remember to stop them down manually before tripping the shutter. My Exa I has a 50mm Carl Zeiss Jena f/2.8 Tessar which is manual stop down.
I have seen numerous Exakta lenses at flea markets and camera fairs. They were usually quite reasonably priced. Wayne has covered them very well.
I particularly like the stop down - shutter release type. I have a beautiful Steinheil München 135mm Auto-Tele-Quinar. The stop down feature can be adjusted for how long (far) it is stopped down before it releases the shutter. Great for previewing depth of field.
The Exakta lens mount is fast and easy to use unlike many of today's more finicky mounts.
Here is my small Exakta Family.
The VX IIa with the Auto-Tele-Quinar is in the bottom left corner. I bought it about 1953 or 54. To its right is a "USSR OCCUPIED" VX IIa. In the lower right corner is my first and last tele extender. A Soligor 1.85x poorly performing piece of gear.

That certainly looks like the right lens. I've a few Topcon lenses in Exaxta fit - RE series. Others were in the UV series and the later PK bayonets, the AM series. I believe the RE series will work, though they lack the external button. UV and AM won't work.
I remember my Uncle Irving, who was considered "rich" by family standards, had an Exacta back in the really early 1950s (He also had a Leica and an Airstream travel trailer). At that time Exactas cost more than $300 U.S. --probably several thousand in today's dollars. Then my dad bought one in the early 1960s for $69.95!. I just noticed that on Ebay the 50mm f/2 Pancolor is usually fetching about $150!
