I have been somewhat lucky in the past using the in-camera meters of my film cameras. I have recently started experimenting with older cameras, both medium format and 35mm. I know that the meters in these cameras will eventually fail and replacement parts will be almost impossible to obtain (especially with Nikon F metering prisms). I have been thinking about purchasing a handheld meter but I am not sure which one to choose and what the major differences are. I shoot just about anything ranging from portraits to landscape, so walking up to the subject and getting a reading might not always be possible for me. I have seen the spot meters but I am not sure how they differ from the other type of meters out there. Also, I don't want to spend a small fortune either. For the prices I have seen on new multi function meters I could purchase a near mint Nikon F2A with still some juice left in its original meter! Any suggestions?
