I'm in the process of testing that lens now, albeit as a Hoya (original
manufacturer) rather than Vivitar (OEM). I've only shot it at 75mm. The
longer focal lengths will be done this evening. The results seem fine at
75mm, but I haven't done the SQF evaluation, yet. One big minus for this
lens is that it is long and front heavy. On my tripod head I find that I
have to rest the aperture ring on the rubber platform in order to get some
balance and stability out of it. Without doing that it vibrates like mad.
But, one can't change the aperture once it's mounted that way. Yuck.
Wait a few days and I'll have a comparison to the 85-250mm f/5 Zuiko. I love
the balance of the latter on the tripod when using the tripod collar.
