Re: M 35-70 f/2.8-3.5 zoom Was: prime keepers

[Joe Wilensky]

I guess I was comparing this zoom to other Pentax zooms of the 
period, albeit the smallest ones, like the M 24-35 and the M 28-50. 
And when I think of M lenses, I think of the tiny primes.

I had an M 35-70 f/2.8-3.5 for a while. Huge and heavy for its zoom range.
True as most of us use f3.5 or f4 zoom in this range.  But what I 
meant was that for a f2.8 zoom, it is small compared to the 
"competition".  Canon equivalent zoom is way longer and more heavy. 
Olympus constant f3.6 has practically the same size.  And now, 
comparing an apple with an orange... Tamron's new "tiny" 28-75mm 
marvel still has 20% more weight and lenght than Pentax M lens, 
although it starts at 28mm and is a constant 2.8.
