Very sharp pictures, sturdy constructed and easy to carry around. Suitable for taking photos of birds and other animals without the risk of being bitten or mauled by these creatures. Affordable telephoto lens and one does not need to spend his/her...

None so far but need to consider the fact that it has no image stabiliser ( you need to spend at least 300% more if you want a telephoto lens with this capability). This lens needs a lot of light and/or a sturdy tripod or shoot in high ISO.

The very quiet operation of the auto focus is very nice. The lens focuses very fast and it gets a good amout of light. Image quality is very nice even in lower light. I really like the range the 100 mm is very sweet.

The lens is heavier than I thought it would be. the maual lens adjustment is is a little close to the zoom ring and is still somewhat easy to get them mixed up; but, I have only had the lens out twice.

Well made but a little heavy. It does have a collar that one can screw in a tripod or better still a monopod. I am very pleased with my purchase which will soon be tried out on wildlife in Scotland.
