I promised myself that I would concentrate only on my beloved short preset teles, preferably Soligor, Komura or Nissin/Sankor made ones.
I'd like to find the super fast ones, or at least as fast as possible... but the fast ones don't come cheap, so my hope lies on the occasional stroke of luck.
I just received a Spiratone Tc 1:2.5 105mm, Sankor made, preset, beautiful zebra livery, highly valued as a portrait lens.
It comes in Nikon T-2 mount, so I have to wait for a cheap chinese PK T-mount adapter that should arrive quite soon.
It is really like new, despite the old age. It looks almost unused.
I was the sole bidder cause the item was badly described: the title of the auction mentioned only the Spiratone tele extender that was attached to the main lens, no reference to the most valuable part of the bundle, the objective itself!
I can't wait to get the mount, so I can try the lens and see if it deserves all the praises I've read online.
I didn't look for this zoom on purpose, I just came across it by chance.
I told myself I really didn't need it, and should have refrained from bidding.
I found the excuse that I would bid so low, that i was practically sure it would sell for more.
Unexpectedly it didn't happen. So now I'm waiting for one of the few vintage zooms I wanted to buy in the past, but for a reason or another never materialised.
After I rationalised that I really don't need it, it came almost by itself
And it's even in PKA mount!
Vivitar Series 1 f/2.8-3.5 28-90mm
From the reviews on this site it seems it's one of the best "standard" zooms of its time.
When the illumination is very low AF zooms start to hunt. Both my "silver" Pentax-FA f/3.2-4.5 28-105mm screwdrive, and my Sigma f/2.8 24-70mm HSM, hunt like crazy at night, especially with fast moving subjects.
If I have to resort to manual focus, I prefer to use a responsive, well damped focusing ring of an MF zoom..
Well, I guess that next time I'll find this kind of conditions the Vivitar could be prove useful.
At the long end is longer than the Sigma, and should match the IQ of the Pentax... at least from what I found in the reviews.
I hope all the positive reviews will be confirmed by practice...
Originally posted by Sliver-Surfer I suggest to use a micro-bubble plastic foil, and a screw clamp/fastener around the perimeter of the filter thread, to avoid deforming the barrel. That filter thread vise can really push hard. Better counteract its force with something holding off on the outside.
It's an interesting instrument, I have one in Italy and one in Thailand
It's really needed to open a bent lens from the front, but it must be used very gently. First time I used it I exaggerated
