    Advise on 12" Metrogon

    Hi,

    I'm new here and was wondering if anyone has experience with this lens? There is one currently on the big auction site and I was wondering about its performance, image circle, etc.

    What format are you looking to cover? With what camera?

    If it's 11x14 or 7x17, a 305mm G Claron will cover stopped down. It also comes in a shutter and is significantly more compact/lighter.

    Per USAF data sheets, the 12"/6.3 Metrogon covers 80 degrees. That's ~ 500 mm. Here's the enthusiast site: http://www.metrogon.20megsfree.com/ If 90 degrees, as people claim on the Internet, 600 mm. The USAF data sheet also says that its AWAR (Super X film, high contrast target, Wratten 12 filter) wide open is 17 lp/mm. A G-Claron isn't it, though, they cover less than 80 degrees. 72 if you're picky.

    If you need an 80 degree 300 mm lens, I think there are better choices, especially considering the cost of putting the Metrogon in a shutter.
