What does the focus limiter swith do?

Jose Carlos , Dec 19, 2003; 09:28 a.m.

Could anyone tell me what the "focus limiter" switch does on the EF 300mm f/4 Lens? I know you can set it from 6 meters to infinity but what is the benefit of this?

Many thanks!

The lens "hunts less" whilst trying to focus lock, rather than going from minimum to maximum focus and thereby taking longer, it is scanning the range of 6 metres to infinity only.

Therefore the only advantage/effect is the time the lens is taking to find focus. This can be critical for action sports situations, ie the difference between getting a shot and not, but not relevent if you are shooting static subjects.

a 6 meter limit may sound abit pointless but it's fairly close to a 300mm
