Hi All and Warm Greetings
I have aquired a Vivitar Series 1 200mm f3.0 lens for the PK mount.
It is in very nice condition, glass is clear, and very little marks on it.
However, it does not focus to infinity, almost but not there.
I also feel it is clearly softer than my Vivitar 200mm f3.5 and Vivitar Series 1 70-210mm (komine) at similar apertures.
I have some experience in lens repair with the Takumar 50mm 1.4 and Vivitar 200mm f3.5.
However, I want to be very careful with this cult classic.
Do advise me if you have simiar experiences.
Many Thanks.
These are my observations :
At infinity focus....
The distance scale line up at the infinity mark
The front barrell also retracts fully
There is only 1 screw behind the hood, it does not look to be unscrewed before. However I do feel some play on the front barrell when I twist it... about 2-3mm left and right. The front element does turn with this free play.
There are 3 screws on the ring just below the grip... there are some paint loss which indicates they could be unscrewed before. There is also some play 1-2mm left and right on this ring.
There no marks on the screws on the mount... but they look sturdy enough to withstand unscrewing without leaving any marks. |
