| p.1 #3 · Sigma 50-500 Biga AF on D7000? |
What kind of subjects are you going to use with the Bigma?
I had shot a Bigma on my 7K and D3s. If you are using the OS you need to prefocus (get it going) and keep the active focus running before the action, that split second or two before you actually take the shot. Once I did that I had no issues with the Bigma on my 7K and D3s.
Sure the 7K was a split second slower, but comparing it to the D3s isnt fair.
I didnt like the F6.3 for high school football or other outdoor sports. No where near enough light and was stuck shooting between 10000 and 12,800 under crappy lights. Not to mention the DOF was so much the separation wasnt that desirable. Not enough blur and isolation of subject.
I just bit the bullet and bought the 120-300 F2.8. Havent shot a night game, but have practiced on other subjects at lower light levels similar and i'm very impressed for what I spent. But then again around 3k compared to what 1600 or so its expected. I also realize it isnt a 400 2.8 prime. I make do.
