I bought one of those kiev spotmeter things. With MF, its just more of a pain to use. It's not like it is coupled with the lens or anything like that. You have to look through the finder, move the thing around, turn it to the side, read the f/stop/shutter combo, look at the lens, set it. Faster if you have a handheld. I sold it and got a plain PM prism for the cost of one of those kiev's new. My old sekonic 398 studio is still going strong.
