Does anyone have experience with the T6-2X Converter on a 300/4 lens? Does this combination produce images of acceptable sharpness and contrast? Is there a better 2X converter for the 300/4? Paul Stenquist

The old version 300 did not have a tripod mount and so was subject to shutter vib at certain shutter speeds. Adding a 2x would cause more overhang and increase the problem. The extra magnification would just add to the situation. The 300 ED would be a much better choice due to vib and color correction issues. I have seen some nice shots with the old 300 and 2x, so it can be done.

Bogen/Manfrotto makes a long lens support which works well with the T6-2X and 300mm/4 lens. It's #234RC. Works well to balance the weight at a midpoint. And I bought it new for under $50.00.

Oops. I got the Manfrotto/Bogen lens support item number wrong in my previous post. It's actually #3420. The other number was the part number for the quick connect.

I tried the New 4/300 IF with the 2x Conv (org Pentax), and got fantastic results at f 5.6 and 8.0. You need definetely a good tripoid and I suggest to use the mirroe lock.
