It seems to me the "Focus Limiter" switch on the Tamron would be more useful in an AF macro lens that is going to double as a portrait lens. Sense you dont want the lens cycling thru the entire range every time your re compose a portrait shot.
Am I off base with this thinking?
Is 'quick shift' more important than 'focus limiting' on an Auto Focus Macro lens?
Not to me. The focus limiter would be far more important when using the lens at non macro distances. At macro distances AF is useless. Catch-in-focus works, but not AF. When I am going for a macro shot, I am looking for a specific magnification. AF will change the magnification. I have not seen a compelling reason for
me to change from my M 100/4. I would like f/2.8, but only for the viewfinder. The macro lens is generally used at f/8 and up because of the thin depth of field.
