MC Zenitar Fisheye throwing off my exposure meter, can it be fixed?

[WhatxCounts]

I just got the MC Zenitar Fisheye in the mail yesterday and might I say it looks very pleasing through the viewfinder. A very nice, full frame wide angle lens. However, theres no connectors like the kit and my other lenses have which I'm assuming is why it cant meter on my camera. How do I fix this? It's on a Canon K2, and I hope I don't have to guess my exposures everytime because I solely shoot tmax film. Thanks in advance!

Welcome to the forum.

You may be able to get by with 'stop down metering'. Check out this link.

Or pick up a hand held light meter.
