I currently shoot with a 55-250, and while I'm getting some images that I'm happy with, they are nowhere near the quality of others on here.
Although something like a 100-400L, or a 400 prime would be nice, my budget doesn't really stretch that far
I've seen that Sigma do a 120-400, which although has the same F-stop range, does give me more length, which will must help? Also it is a lot cheaper, basically, and I wondered if it is any good for motorsport? Does anyone hear use currently, or has used one and can give any feedback on it?
Thanks in advance.
