Canon 100-400 f4.5-5.6 L Field Test

The weather has been pretty good for the last few days so I was able to manage a trip to the London Wetland Centre in Barnes and a local nature reserve, South Norwood Country Park.

Over all I have been extremely pleased with the lens. It handles well, the AF tracked well in AI servo and seemed bang on in one shot modes. As for the sharpness at the long end I have no complaints at all.

Below are some images taken over the last couple of days, these have had some Lightroom processing but no sharpening at all. If you click on the image I have included large jpegs.

In my opinion it's a great lens, as to whether I will buy one that's a tricky decision. As the shots above will testify I was mainly shooting at 400mm or longer so although the convenience of the zoom is tempting I am not sure that I can justify the outlay if I will only be using it at a focal length I already cover.
