Great question today from a reader:
QUESTION: Mike thanks for your newsletters. They are great and very informative for me. Thanks again
Question: I have a D700 and a 70-200mm f/2.8 G ED VR II lens and want to bug a teleconverter. What do you recommend, the 1.4, 1.7 or 2.0? I would appreciate your advice.
Again, thanks for the help and I hope our paths soon cross again.
The TC-14E II is very good with the 70-200 f2.8. I use it with mine all the time. I get excellent results and excellent sharpness.
TC-17E II is pretty good. You’ll get good results and decent sharpness.
TC-20E II is terrible. Don’t buy it. In fact, this model is discontinued.
TC-20E III is great. New optics greatly improve is performance and it is now regarded as a great optic.
So, which one to buy? That’s hard for me to say since I don’t know your end use. In my case, I bought two TC’s. The 1.4x and the 2.0x. I use them depending on what I’m shooting and how much more reach I need for a photo.
