there's often a pay off in quality using things like doublers and we can see it here.

The detail is blurred, the contrast is low and the colours muted - all things that can result from doublers. If you've got an F2.8 you may get better quality... but an empty bank balance Wink

I'm sure someone with bird photography experience will help more on the "shooting birds" side of things, but I think the quality issues are down to the doubler, and maybe a heavy crop?

Quite honestly, if your converter is by Nikon, you should tell little difference. I use a 2X Sigma EX converter with my 50/500 Sigma DG EX superzoom and, providing I am on a VERY sturdy tripod, it is difficult to tell the converter is on. (Cheap converters are a different matter!)

The lighting is against you and the head is thus dark, loosing detail. I also, rarely, like rear view shots of birds. You may have a little movement as the image does lack crispness.

Were you in range fr a burst of flash - my Sigma 530 guns have vast range - 20 - 30 metres at ISO640. That would lift things as in human portraiture. At 1/50, you were asking a lot to get pin sharp results though.

It Is a Nikon converter the TC301. After examining the full size file at 100% there is a slight movement as you have suggested, and i do mean very very slight. I had wondered myself if it is the lighting, the lens alone gives far better results but then i gain 2 stops. will attempt another shot with a flash, i have a sb800 which should reach the distance. i also noticed the lens was itself set on f8, so i am thinking its true reading was two stops more and this wouldnt help it.

The actual aperture with doubler is f16. The real problem is 1/50 second. You are going to struggle to get a sharp image, even on a sturdy tripod, of moving subjects at these settings.

It is often better, even with quality converters, to use the prime lens and crop the image.
