confused about use of teleconverters with 600 mm non vr lens

They do not look good, Stuart.
Hi from Wyoming.
Stuart,
I've made very sharp images using the Nikon TC14-E, Kenko Pro 300 1.4 and the Nikon TC20-E (First Version) on the Nikon 600mm F4 AF-S (First Version). Not so much with the TC17-E.
You must use your best long lens technique and I have found stopping down 2/3 to a full stop does make a difference in sharpness.
If your lens / body combo is out of calibration in the least, the flaw is magnified when you use TCs.
Fortunately, you can calibrate each lens / TC combo with most new pro level camera bodies.
I use the Nikon 1.4 teleconverter and 600mm AFS version 1 with acceptable results. This is 600mm non-vr with 1.4 on a boat at a slower shutter speed because of falling light

I used both the 1.4 and 1.7 with the non-VR 600 and was very pleased with the results. I agree with James re: long-lens technique.
I regularly use a Nikon 600 non-VR with a TC-14E with excellent results. Requires very good long lens technique and I may not get quite as many keepers as I would with a VR lens. Keep in mind that many, many pros used TC's with non-VR 600mm lenses for years before the VR lens were available.
I agree with the long lens technique on such a focal length.
Last year, I managed to get very good results with a 600mm AI-S+Kenko 2x and a 600mm AF-I+Kenko 2x.
Here's a shot with the MF version one :

Yep, the VR version allows me much higher keepers, even with stacked converters !Quote:

I use an old MF 600mm and Nikon TC301 2x all the time for moon shots. I've gotten some really sharp shots from that combination HERE. Don't know if they would be up to birding standards or not. Never carried it afield because it's just too darn heavy..
I also only shoot the 2x and 600mm off of an old "Magestic" video tripod that weighs about 30 lbs. Tt's quite steady and good for moon tracking with it's geared head (probably useless for birds).
