| p.3 #5 · Push/Pull Zoom vs Rotating Zoom Ring |
Never had any problem with the 100-400L either. Faster way to zoom than a rotating zoom I reckon.
I suspect the issue or weakness of push/pull zoom had been exaggerated by internet parrots. If you use it with an open mind, it won't be long before it becomes second nature.
I dont know what you mean by weakness, but as far as accuracy, a twist or rotating zoom is MUCH easier to control precisely than push/pull. This is a fact. There is a reason primes are not push-pull focus...
You are probably right, but that zooming precision is of no practical consequence.......I can not imagine a situation where I'd need to fine tune FL to within 5% or some such. However, the manual focus requirements are much more exacting, and I suppose a telescoping kind of MF mechanism wouldn't work as well as the standard rotary type.
It's very important if you are tracking moving targets, especially things coming to / going away from you...
