Shooting with Sigma 50-500mm f/4-6.3 EX HSM for Sony

This lens is a beast......but a very tamed beast. The Sigma 50-500mm gives a range not matched by ANY other telephoto zoom that I've seen for the Sony Alpha system, it’s reasonably sharp throughout its range. I wish it weighed a bit less but with a sturdy tripod or monopod you could get some really good shots. You can hand hold it just as long as you have plenty of light and maintain stability. Construction, fit and finish of this lens are just excellent.At the end of the day, it just does the job you want it to do. And it has some very nice touches: the ‘handle tripod mount’ is something I wish other manufacturers would copy on their telephoto lenses,The markings on the barrel are easy to see,Focus is fast and quiet combined with Sony's image stabilization that is built into the camera makes this lens a top pick for photographers of all types.

This big cat was pacing back and forth waiting for lunch. It was pouncing and scratching at the door. Then it decided to take a dip in the water...I was hoping to capture it growling and I scored the shot.

Scored this shot while the Cheetah was calmly pacing about in its pen. This is the closest I will get to a cheetah unless someone can score me a ticket to Africa so I can see them running in the wild.
