Hi everyone. I know I'm mad but I would like to find a good solution to my current condition. I broke my arm 5 weeks ago and apart from misery and agony I am trying to recover from boredom. I have been going for walks the last couple of weeks but most of my camera gear is too heavy with one arm. Last year I asked for advice at this forum and was happy to get the Nikkor 200-500, but now it is impossible to use it and I think it will be a challenge in the future. My arm is pretty bad and it may take a long time to recover. I also have the Nikkor AF-S 80-400 VR, the Non-AF-S 80-400, the Nikkor AF-S 300 f4 non-VR and I have been using my Nikkor AF-S 70-300mm G VR. The latter seems most usable on the D800 with one hand although it is not easy and results are not as nice as with the bigger lenses. My question is, what do you think about getting the 300 f4 PF? I went into a store and picked up the display model and was excited by the light weight but I don't know if it would really be that different to what I have. 2 grand is a lot. I have the teleconverter 1.4ii, (not the iii) but I'm not sure whether it'd be worth using with the PF. I guess I need to be patient but I have plates in my arm for another six months. I have rehab once a week but I'm not to pick up heavy weights. However, I know when I'm down birding is the best remedy. I look forward to your thoughts. My Nikon bodies are D800, D7100, D300. I like the bigger bodies to grip with one hand. I was gonna get the D500 but I'd still be struggling with heavy lenses.
