Rotating Switch on Minolta 100 Macro AF 2.8
« on: April 22, 2015, 02:10:35 PM »
Just received a new-to-me Macro lens (2nd Gen. 1993-2000) with a rotating switch on the lens barrel. Two positions: FULL and LIMIT.

How is this used and what positition should it be at in normal operation.

If you switch it to full the the camera goes all the way focus, from close up to infinity.

If you switch to limit then you limit distance but right now i don't remember if it is for close up to mid range or from mid range to infinity?
When i go home i can check and report. Which camera are you using?

If it is a99 or a77II you don't need to use this switch since the camera have in body focus limit range ( AF range)

PS: After checking the limit switch can limit both ends the close up to midrange and from midrange to infinity. To use this  function,  focus to either end and then turn the limit switch. Then the camera will use the focus range you have selected

the Tamron 90mm I have has a focus limiter too, it lets you shorten the range at which the lens will focus to and from to make it lock on quicker..........................
