Teleconverter for Nikon 70-300
I am going to try to photograph the solar eclipse in August. I have a D90 and I plan to use my Nikkor 70-300mm f/4.5-5.6G. I started looking at teleconverters and it seems that the Nikon TCs won’t work with this lens. Does anyone have any experience with other brand TCs with this lens? I’m also wondering if the 1.4-2X hit on f/# would also be prohibitive. Maybe I should just stick with the 300mm focal length. I am concerned that the third party TCs would have poor image quality with this lens. Any thoughts or suggestions?
