Santa/Father ruddy Christmas brought me two presents this year, both of them very similar:
1) A sort of stuck diaphragm for the Nikkor AIs 50mm f1.4 lens that I've had for a few years, which could've been down to oil on the blades (oil which hadn't been there when I bought the lens).
2) A sort of stuck diaphragm for the Tamron CT105 105mm f2.5 that I've had for about a year.
It seems the 50mm has been fixed but the 105mm "needs a part" which the tech doesn't have. It seems the tech didn't tell the shop what part it needed, or whether the part can be taken from just ANY lens or if it had to be a Tamron CT105 105mm lens. The shop said they'd send it to another tech who may have the necessary part.
To put it simply, Santa/Father Ruddy Christmas has decided to bring me the present of making my wallet lighter by about £140 IF the Tamron can be fixed. If not, I'll have to decide on whether to risk buying another Tamron or sped 2 or 3 times as much on a Nikkor AIs 105mm f2.5.
Thanks a ruddy lot Santa/Father ruddy Christmas!
