ownership:I own this lens
compared to:200/2.8
Tokina 400/5.6 (not fair)
Sigma 400/5.6 macro (fair, a super performer)
Big beercan (not fair)
price paid:650€ (used)
Almost none CA (even in extreme conditions).
negative:This lens weight alot, but there arent any lighter alternatives.
AF isnt lighting. HSM whould be awsome on this lens.
comment:300/4 Is an excellent comprimise between aperture, focallength and weight. This lens gives you a 300/4 plus the flexibility of a zoom. The sharpness at 300mm F/4 is excellent, no need to stop down unless you whould like more DOF in the shot.
Ofcourse using a TC on this lens is very tempting, 300/4 becomes a 420/5.6 . I bought the Sigma apo dg 1.4x TC and it works miracles on this lens. A tc always steals a little quality but in this case I find it really little. 420/5.6:
See more testshots in the sample shots section of this lens. Both with and without TC. I often use 420mm wide open, and Im very satisfied with the results. But remember that 420*1.5 is 630mm, and that is a lot of lens to handle.

Even if I switch system Im propably getting this lens again. I love it. The flexibility of both zoom, 300/4 and 420/5.6 with excellent quality suits my photagraphy great.

Cheers /Alve
