I own a nikkor 70-200 f:2.8 vrII for my D700 and i wonder if there is a soloution for that rare occasions (e.g. shooting the moon!) that 200 isnt enough . i dont know much about tele-converters but i think they are there for increasing the range to i dont know 400 maybe!
another question is about the possibility for the information to be recorded on EXIF correctly, and of image quality of course! has anyone used them ?
