Popped along to Goodwood yesterday morning for just over an hour to test the Sigma 150-600mm Sport lens I am borrowing. Used it on a 1D4 and also had a 1D2N with a 24-70 for some wider blurrier shots.
The Sigma is certainly no match for a prime lens in AF speed or consistent sharpness. AF is decent but wasn't as snappy at locking on as I would like, a few times it just didn't react at all. Even in sunshine ISO400 was typical (for 1/500sec shutter) which means when overcast much higher will be needed. I was shooting mostly at F7.1/F8 at a range of zooms. Nice to use, could push-pull on the monopod but I did find quite a lot of softish shots - maybe acceptable for some people but I do always aim for critical sharpness. Can still produce some nice shots though, no doubt about it, like anything will take getting used to to get the best out of it!
Here's a few shots linked from my Facebook. Few more on there and a little gallery on my site. I was only there for less than 2 hours though.
#1 Alfa
#2 Alfa
#3 Alfa (taken with 24-70 lens for some variety)
#4 Alfa
#5 Alfa
Cheers for looking. Comments appreciated. Certainly an interesting lens, anyone else got one and used for motorsport? How are you getting on etc?
cheers
