Taylor-Hobson Ortal 3 Inch f2 TV Lens - Photo Set

After a few iterations of trying to get the Taylor-Hobson 75mm f2 TV lens fitted, I have finally settled down on the Yeenon 18-33mm focusing helicoid. The width of both the lens and the helicoid are almost the same, making them look nicer together than the cheap generic helicoid I used before.

This lens has a nice, big imaging circle and I think it even covers full frame, but due to very short lens flange, it's would be very difficult to make it focus to infinity without major modifications. When I bought it, it had a geared aperture ring, which I removed, and put on the rubber covering instead. Because the lens body is mostly made of brass, it's very heavy.  Even the 12 aperture blades look like they were made of brass. The glass itself is very yellow, suggesting that the elements may be radio active. It was common practice in the old days to use thorium in glass to increase the refractive index.

I have never seen a better built lens than this one. It truly fits the phrase "built like a tank".

Mated with Yeenon Helicoid. Looks nice, no?
