Does the 2x TC Work Well with 600 f4?

[yyjDennis]

I'm going to break down and order the 600mm f$ lens. (Funny, I always find myself pressing the shift key when typing 600 mm f$. Must be a freudian thing.)

I'm wondering whether I should get the 2x TC to go with it. Has anyone used this combo? Can you comment on the image quality effects of using the 2x with this lens?

Thanks,
Dennis

Dennis, Mark Galer continually states he prefers the 1.4 TC because there is almost no loss of IQ, but he says there is a noticeable IQ loss using the 2.0 TC. He has a page on Flickr (www.flickr.com - Mark Galer's Albums) and has many test images there which are well documented. He has 3 pages of albums, just thumb through them to find the appropriate test. He will also have a test of your 600mm $4 lens as well. Happy hunting.

It does work fine but I see a small drop in IQ when using it compared to the 1.4. Having said that I'm guessing most of us would want to use the 2x when subjects are some distance away so logic says you are always likely to lose some IQ at long distances irrespective of what you are using

Thanks for that. I watched his video review of the 400 2.8 and looked at some of the flicker images. It does seem that the 2x TC images aren't really as sharp as I would hope for. I think I'm going to stick with my 1.4.

Thanks,
