Hi gang!
	I'm looking for a zoom (or vari-focal) lens of the
70-210mm (or similar) range.  Camera is a Canon T-70. (has
everything but the rs-232 connector :-)  )

	The new Vivitar series 1 70-210mm f/2.8-4 seems
pretty nice. The controls are nice and smooth, it doesn't
change focal length when tilted, compact, light.  Anyone
have one of these things?  How is the optical performance?
How does it compare to the "big name" lenses (Canon, Nikon,
Leica, etc) Will the variable apature(sp?) cause any problems
with the light meter? (not counting bizzareness such as
zooming _d_u_r_i_n_g exposure) If I zoom in, lock the exposure,
zoom back out and release the shutter, will the exposure be off?
(yeah, I might want to do this, even with the 11% spot)

	Canon has a 70-210mm f/4, but it's hard to believe they
put their name on it, it's such a piece of garbage. Big,
heavy, slow, changes focal length when tilted.  They also
have a 80-200mm I haven't seen, which is much more expensive.
Should I look at this one?

	Also saw a Tokina (I think) 70-200 (approx) f/2.8
which is nice and fast (2.8 even at 200), and has a tripod
mount.  It's bigger (but well balanced), not too heavy, and
more money.  Controls weren't as smooth as the Vivitar,
dispite it's supposedly being a "better" lens.

	Any other lenses I should look at?
	
Important features:
	full coupling for auto exposure
	good optical quality
	fast
	good mechanical quality - smooth controls, doesn't move when
	 tilted (if one-touch variety)
medium important
	weight and balance
somewhat less important
	size
	price
	tripod mount
not important
	true zoom
	stops down to f/500,000
