p.2 #2 · Lax with Sigma 300 2.8 prime | |
Hey Ted. Well, on the 1.3 crop body the 400 2.8 was great! maybe a tad too long for some things, but for field sports it was great! when I started to use the 1.6 crop of the 40D the 400 was really too long! I sold that and picked up the 120-300, and then the 300 Sigma prime. I agree with you that the Canon prime is sharper than the 120-300, but compared to the Sigma 300 f2.8 it is closer than I thought it would be. And with the 1.4x tc on the Sigma it doesn't seem to slow down at all, where there is a slight slow down in AF speed with the canon. No doubt, the canon primes are as sharp as it gets, and AF a hair faster with out the TC on, but I would say they are $300 sharper and faster, not $1400 sharper, and faster
