Hi all. Somewhere on this site of all knowledge is a piece about the basics of resetting focus after disassembly. Can I find it! Can I !!!!!!! Anyone help? The lens in question is a Viv 135/2,8 which I bought for peanuts as it had an oil leak blades nice and gooooooy. All done now and looks great, just need the above so I can go and play in the sunshine. Take care all. B.
