I'm sure a rental trial would indeed let you know if it fits your needs...but I can say I was initially worried about no MLU too. Then I got one, shot many rolls, and saw no introduced vibration from the mirror causing decrease in sharpness. It actually let me part with bigger, heavier F-series Nikons. Yeah, that 9-hole socket for release is goofy. But the camera works wonders. I've shot it up to 200mm, on and off tripod and not noticed any difference from a 'control' camera with MLU I set up to test with.
