p.1 #15 · p.1 #15 · Canon 300/2.8 II + 2XIII vs Canon 500/4 I AF / IQ comparison ? | |
I have the 300 v2 with 1.4x and 2x III extender now, and had 500 v1 several years ago. 300 v2 with extender produces very good IQ, even with 2x III, but when considering AF speed, I will not use 2x for BIF, it's much slower than 500 v1 bare lens. The reason I switch from 500 to 300 was the weight (and my age), but since I got my 100-400 II recently, I am considering to switch from 300 to 400 DO v2 or 500 v2, though sometimes I may need F2.8 in low light condition.
