Hi everyone,
I just got this Tair 3 lens along with 500mm 3m/6a mirror and am very pleased with it...I have one issue though...
I dont mind preset aperture as I have quite a bit of lenses operating the same way but on this lens it operates kind of funny and I think it may have some sort of problem/fault.
If i got it right I have to set aperture ring to desired value, cock the ring with red button to achieve full aperture opening and when I push lever beneath the lens it recoils and goes to selected aperture value...right? Right! :)
Problem is I can do that only on distances from 10 meters to infinity. When the lens is set to anything lower than that (3-10 meters) I cant achieve recoil action as the red button ring does not click and it does not open aperture fully ... To clarify further ...when lens is set to 10 meters and further I can feel stifness and tension of the coil ring but set lower than 10 meters it feels kind of loose and kind of "skips" or starts coiling not from the moment when I start rotating it but somewhere in the middle of circle to the end where it should click and recoil.
So if I want full aperture openng at below 10 meters I have to set the lens to 10 meters and above and then cock the ring and then return lens to below 10 meters and shoot wide open.
I wonder if position of the lens barrel is influencing somehow and making it behave that way or coil is loose or whatnot ... I have the tools, I just dont want to reassemble it and make thins worse before checking with someone who has done it...
So any info would help
Cheers guys.
Thanks
Mark
