Well I got my Kenko 300 Pro 1.4 today and I must say, I like it! I cannot compare it to a Canon as I do not have one, but I do not think I need to spend the $$$ on a Canon either.
I tested it on my 400mm 5.6L and my 70-200mm 2.8L V2 and they AF worked great on the 70-200mm, no problems on the 70-200mm 2.8, at all.
I can see/tell the AF is a little slower on the 400mm 5.6 and cannot lock in as well as the bare 400mm w/o TC.
I have not done a test, on image quality, I just tested the AF and checked the differences of reach on my 5D2 and 40D. Raining too hard for me to go out and set up.
I have a question though, hopefully someone could help with my math or tell me if I am wrong on the equation.
On my: 5D2 + 400mm + 1.4 = 560mm >>>correct?
So would'nt it come out this on the 40D?
40D + 400mm + 1.6 CV + 1.4 = 896mm >>>
The reason I ask is when I look at the data on the image information, it still said I was shooting 560mm focal length on both cameras.
It is not a problem I just want to know if I am right or wrong on my math. Never really used a TC before and I use FF bodies mostly, but I got the 40D as a back-up and to get a little closer to Wildlife if needed.
Thanx in advance!
