Originally posted by Alizarine I don't see the node on my FA lens too so, probably it went out when AF lenses went in?
The F series AF lenses still do have a little knob at the same position, the FA lenses don't have it anymore. Only the 3 FA limiteds revived that nifty feature, but in really silly colours. My black FA 77 has a green bulb...
Personally, I use the knob much more often to attach a lens then the red dots... Just align the bulb and the lens release knob and attach it.
Unfortunately, the recent digital bodies have moved the lens release knob a little bit downwards. It still works, but not as precise as before.
