p.1 #2 · Sigma 120-400 good for airshows? | |
tried it when it first came out but the AF was poor and the iQ not very good , better than its bigger brother (150-500) but still not very good. If they have sorted this out then it might be worth a look. I had the 100-400 at one time also and would recomend it to anyone wanting a long zoom. Its not the fastest AF out there and the IS is only good for 2 stops but is IQ is great
