Many thanks to all the contributors here for the guidance and inspiration (Mike, that last Seattle cityscape almost induced acrophobia!): I am now awaiting arrival of my own 'new' Vario-Sonnar 100-300mm from Japan, and I am plenty excited. While I hesitate to appear to endorse them -- for good reason -- I can't help liking the sum by which eBay subsidized my purchase with '4x bonus' eBucks -- a fortuitous arrival of the promotion at a very opportune time! Barring unpleasant surprises on arrival (unlikely in this case), a very good deal then on a very clean, little worn example, I think. Sometimes the stars do seem to align, fantastical happenstance as such a musing may represent.
This Zeiss joins a Distagon 25mm/2.8 ZS, a V-S 35-70mm/3.4, an 85mm/2.8 Sonnar AEJ, along with Contax G 21mm, 28mm, 45mm, and 90mm, among the other lenses I am fortunate, or old enough, to have gathered. I am still assuming that the Techart "AF" adapter is my best option for using the 45 & 90 on my recently acquired Sonys. Any contrary opinion on that? I am not very concerned with the AF limitations. ...BTW, does the 28mm G have a shot at being useful on my A5000? I note that DxO found the A5000 to produce nearly 1/3 stop less vignetting than did the A6000/A5100 with ALL the same set of e-mount lenses. Interesting, no?
I will be using the new lens on Pentax K3 and Sony A7/A5000... and likely, on a complementing Pentax K-S1 20-ounce, 100% view full pentaprism, image stabilizing "second body" ...soon, as well. Some people see, on occasion, Pentax fails, and no more... others see opportunities in the making to fill a niche at a silly price.
*My question*: Can anyone here advise on whether far eastern knockoffs for the Leitax approach to lens bayonet swapping might be worth considering, at least initially? Besides looking for compatibility with all of my camera bodies, I would also like to be able to employ my Kenko SHQ DG 1.4x teleconverter for Pentax K-AF with the Vario-Sonnar instead of also needing to purchase and carry a Mutar TC. Any sound advice will be much appreciated! Thanks.
