Was skeptical about digital focus confirmation in old SLRs for years - now I'm a convert

I spent about 8 years doing all my focus tuning by eye on vintage Nikon F bodies. Thought the whole idea of a microchip telling you when something's sharp was just gimmicky. Then I picked up a $40 adapter for my Canon 5D that added focus confirmation chips to manual lenses. After 3 rolls of film where every single shot came back tack sharp at f/2, I had to admit I was wrong. The chip reads the sensor contrast way faster than my eyes can catch micro-focus shifts. Has anyone else gone from hating these things to using them full time?

Same story here, those chips saved my old glass from collecting dust.

Tossed mine in the trash and went back to plain glass, @wright.jesse found the chips ruined the light.
