Re: M80-200 vs F70-210 ?

[Joe Wilensky]

Well, I haven't used variable-aperture zooms on manual cameras very 
often -- they are far more useful and there is less inconvenience 
with cameras with at least some auto exposure, because the camera 
would then at least adjust for the changing aperture value when 
zooming. But my point was that the variable zoom "feature" alone 
would not cause improper exposure, though it certainly does add 
another element of inconvenience to its use with a manual camera.

I have the F 70-210 zoom, and I would be less likely to use it on a 
manual focus camera because of the poor manual focus feel alone. The 
loose focus feel (giving a feeling of imprecision) and very thin 
manual focus ring, I think, knock it out of contention for use with 
an all-manual (and manual focus) camera in favor of the M 80-200, 
even without taking the variable aperture issue into consideration.

So have you ever shot with such a zoom on manual camera? This seems to
me like you didn't. Adjusting exposure WHENEVER you change the zoom
setting is far from convenient, it's a complete "pita". Especially
with a camera with full stop shutter speeds (as most manual cameras
have)
