Help with Long lens

Hi all

I shot lots of birds, and have been using 400mm A 5.6. Good lens, but it does not communicate FL into the camera and I often find myself forgetting to input FL. Also AF would be useful.

I tried Tokina 80-400 but dont like the IQ (my 55-300 is better at all FL based upon extensive comparison of news print and Brick wall test shots, let alone field use).

I once had and return the Bigma (non OS) to KEH. That waas pretty good but heavy.

I am considering the 300 DA* with a TC (need at least 400mm) but I am not sure that lens information and AF is kept with a 1.4 TC. Can anyone provide me some recommondations on a TC? This would be my prefered combination for size reasons....(more portable than a Bigma).

I would consider a Bigma again or the 150-500 if the above combination does not work.

Da*300 and 1,7 AFA is a frequently used combination around here. I have it myself.
It can deliver good IQ, but I find it to be pretty inconsistent.

The cons are, 1,7AFA is no longer made, and can be hard to track down. Af works, but takes a hit for sure. You loose some light, which also darkens your viewfinder (irritating to me at least). And it degrades IQ. More often than not a crop from the DA*300 will be better (super sharp lens, and I can often crop to 100% for web-images etc.). This is just my experience (Im very picky on IQ and I pixel peep..), many other are very happy with that combo.

If you can afford it, the 500 f4,5 sigma is the choise in my opinion.
