Re: the 35TI. I fired the shutter a ton of times on the weekend and it seems to be a bit better. Still happens, but I found if I give it a whack on the base plate before taking a shot it doesn't double fire. Not ideal, but better then having it as a paperweight.
Yashica T4, Ektar + c200, Asda developing (hence obliterated negs/all the dust, lol).
