Review on Sigma 150 600Mm 5 6 3 Contemporary Canon by David Crawford

All I can say is wow. This lens is amazing. The sharpness is incredible. See attached picture. I'm sure Amazon compression will lose quality. I've photographed the moon, people, animals and every time the quality is excellent. I'm definitely glad I made this purchase. The first image of the moon was a still image on a tripod. Second image of the Orion Nebula with a star tracker and a tripod at a full 600mm. I added 30 x 30 second exposures from manual exposure. This lens will definitely come in handy if you are just getting into astrophotography. There are other options for astrophotography, but the ability to capture stars, animals, and other objects makes them versatile. Make sure you have a very stable tripod if you are thinking of astrophotography with this lens, for other subjects I would recommend a good monopod. You can hold it in your hand, which I did, but it can feel heavy for long periods of time.
