[QUOTE="robbins.photo, post: 324206, member: 27043"] Ok, well teleconverters will cut the amount of light coming in from the lens. For a 1.4 you'll lose 1 fstop, for a 2x you'll lose two full fstops. A 2x can be useful but only on a fast lens, something in say the F4 or F2.8 range. You don't want to use them with slower glass like an f5.6 or you will most likely lose the ability to autofocus. If you think 300mm would be enough the nikkor 70-300 mm afs g vr is an outstanding lens but I wouldn't recommend using a tc with it. Sent from my LG-LG730 using Tapatalk [/QUOTE]
