Hi Dan. MM
The Sigma 80-400 that I lent you on Nic’s boat is about 300gms heavier than the Canon 70-200 f2.8 IS USM that I was using. But after five hours of photography it felt like a ton!!. I find that the Sigma is not too good in the low light conditions that we had in the late afternoon. Auto focus might have been a problem when you were using the lens ,as if you remember Nic was heading pack to the pier against the wind and tide at about 15-17 knots. Some of the pics I took with the canon could have done with a bit more reach, but I found that I did not loose too much quality when cropping the pics. I have a x2 converter and will try it the next time. If you want another try with the lens in better light give me a pm.
Charlie.
Thanks Shutterbug. I have a flowering crab apple, (Malus Golden Hornet) in the garden and every spring the bullfinches gorge themselves on the emerging buds. Its a wonder it flowers at all. An added bonus is the tree is laden down with yellow crab apples in the autumn that attracts a variety of birds throughout the winter.
