I posted all the pictures from our Alaska trip online. They can be found here: http://www.lokeshshah.com/gallery/. I have also tried to add a small description to each photograph mentioning the context.
In general the photographs are not very good. Most of the shots taken with the Sigma 70-300 APO and 1.4X TC haven’t come out to be very good. The combination of low light and shooting handheld led to quite out of focus shots. I have started to think about getting a faster telephoto and a monopod.
