| p.1 #1 · 1.4x mark 1 & 11 questions |
I am a hobby photographer who likes reasonably good gear, have a 20D and a 7D, several older L zooms, couple select primes and a 100 USM macro. I have a 300/4.0 L IS on the way and have rented a 400/5.6 that I really liked. So, to make the 300 due double duty I am considering a 1.4x TC. Will it really matter to me whether I choose a mark 1 or mark 11? Are there any glaring drawbacks to the mark 1?
