I've been putting off geting a decent bird lens for over a year but with prices starting to rise I think I may have to act soon.
Have a Canon 40D so my first thought was their 100-400 but it is a bit on the pricey side and in many outlets has increased by around 10% over the past few weeks. Also, I have agonised over some of the larger prime lenses, at least the more reasonably priced options, with a 1.4x converter which I already have. But most of them have a rather long minimum focusing distance which causes a problem when that rare butterfly lands 6 ft away.
Although I am looking for good value I am not necessarily searching for the cheapest if it means a loss of quality. I have seen some good reports of the Sigma 150-500 which rate it above the Canon 100-400 and the well known Sigma 50-500. At a little over £600 it does sound excellent value for a stabilised lens. Obviously more of a summer lens and not really suitable for low light conditions.
So does anybody have any experience of this lens?
