I bought my 100-300 off of another listmember some eight years ago 
and used it regularly, but my big complaint with it is that it is too 
slow, especially at the 300mm end. A few months ago I dug out the 
Series 1 (Mark's version 2) and started using that. It's an F3.5 max 
aperture throughout its range, so that is better, but it's manual 
focus (and a one-touch, which I don't really like) and non-A, so you 
end up fiddling wit the green button. Optically, though, it is 
wonderful, and the close focus ability is great to have.


Down the road I'd like an F2.8 zoom in that same general range, even 
if it means going with a Sigma or Tamron.

Mark!

Thanks for everyone's words of wisdom.

When all is said and done, I've decided to forego the 70-200 and
stick with my Vivitar Series 1 70-210, and to give my FA 100-300
F4.5-5.6 another chance.

2013-05-29 Thread P.J. Alling
I believe the Takumar F and the Pentax, (not SMC), F in 70-200 are the 
same lens with different names. The Pentax F IIRC also came in FA like 
livery but was pretty much the same lens as the Takumar.  The FA 
70-200mm f4.0~5.6 and the F 70-210mm f4.0~5.6 were different optical 
formulas.  The F is supposed to be better optically, (sharper, whatever 
that means, since there's no objective measure of sharpness), at the 
long end, the FA has better electronics and coatings.  You pays your 
money and you takes your choice.


Here's a sample of the SMC-P F 70=210mm at 210mm wide open.

The F 70-210 is the best of all of them, a good copy will be sharp 
though out it's zoom range, a bad copy will be a little soft at 210mm

Are you sure you meant to put that qualifier there?

AFAIK the F line (effectively the first auto-focus series)
had multi-coating, just like the earlier M and A lenses,
and the subsequent FA lenses.  The difference between the
F and the FA lenses is mostly in the information that is
transmitted over the digital signal pin; while the exact

lenses also tell the camera the focus distance the lens is
set to, which allows for more complex exposure metering.

Steve,
The FA 70-200/4-5.6 with the power zoom for the PZ-1?
I was quite happy with it, still own it.
But we called it the wobbly one.
It would wobble a bit while focusing,
but never showed bad pictures as a result.
