Hallo. Recently, I was out taking photos with a nikon fm3a and a 135mm manual lens. I was shooting off a bridge - late afternoon, teams of rowers on a broad river below etc. - and I got off a few shots before the boats moved quickly out of range. The shot I would have liked to take was too far away. I have decided to get a 2x teleconverter for the nikon fm3a instead of a longer lens but have no experience of teleconverters. Can anyone recommend any brands? Or contribute any tips? etc. Or share experiences? Appreciate greatly any help or advice. Cheers M.
