I'm obviously out of my league here but I'd like to ask a Q. :
how much degredation will you get with a 1.4TC on a 300 f2.8 taking pics at f4- 5.6 (with the apc sensor that would be essentially a 600 f4 lens)? I ask because I'm not sure I can justify both a 300 2.8 and a 500 lens right now....
thanks
I have to say this, If I could only keep 1 lens out of my entire kit, it would be the 300/2.8L-IS. Image quality degradation with the 1.4xTC is almost undetectable. This is the only combination I can say this is the case. I have many large prints, 16"x24"+, in my home taken with this combination.
