Hello everybody! In recent posts, I've learned I'm able to use old Takumar lenses on my Nikon. I have a couple of questions: 1- Does this apply to the 49mm screw mount lenses? 2- I own an F50, but may be able to switch to a F70 in near future; wil the 70 retain the metering when using manual lenses or do I lose it as I do with the F50? And another question, this regarding the actual F50. I'm planning to go to Europe next winter, and I suppose I'll get some pretty cold weather. Am I supposed to have any trouble with low temperature with this camera? Thanks!!! Patricio Murphy [EMAIL PROTECTED]
