[Black] What a nice lense and for that price. Good deal

[Black] I have just returned from Florida where I used this lens extensively photographing birds and am very pleased with the results. I hand held it throughout my trip. I would recommend it to a friend.

[0.205 lb] Have used this on 4 outings (2 zoos, a horse farm, and a walk in the park) so far. Am very very pleased w/ it. Makes me want to upgrade some of my shorter lenses to better glass. It is heavy, but especially at the zoo's & the horse farm where I could usually find something to lean on, I was able to shoot & get great pics hand held. Not so much at the park. Needed the tripod there.

[Black] Researched this purchase for months. I relied on B&H 's reviews as well as reading through any other information about this lens that I could type into a search bar. I had purchased Sigms art lens recently and was very happy with quality of the lens and it's capabilities. The 150-600 contemporary zoom is big and comes in at around 4 and a half pounds and it is well worth carrying to get the shots you can get. My first big day to test the lens was at a spring training Baseball gain and the pictures I collected are amazing. Close ups from the right field bleachers and from behind home plate. Mounted on a Nikon D7200 with a monopod the images were sharp and I was able to stop action beautifully. Since then I have shot wildlife a including birds in flight with brilliant results. Could not be happier with this lens.

[Black] I use this lens on a Canon 70D for bird photography. The lens works very well in auto focus and provides very sharp photos. I also recently bought the 1.4x 1401 extender which gives me additional range. This extender works well in manual focus with the 150-600mm contemporary lens on the 70D. I don't think that the extender will work with this lens in auto focus with any of the Canon DSLR cameras.

[0.205 lb] Since I'm not the steadiest person, hand holding will not be my main method of shooting with this lens. So far, I've only had a chance to use it indoors with my bird feeder shots. I've placed a bean bag on my window sill and supported the lens on the bean bag holding up most of the weight,while trying to steady the body as best as I could. This has worked well for me. The focus-limiting setting is nice for quick focusing in the close zone (2.8-10m) I don't think the Tamron 150-600 has the close focusing zone option. As soon as the weather breaks, I plan to put this monster on a tripod and check it out at the local lake.

[Black] If you want to reach out and get sharp pictures then this is your lens. One thing to note is the weight and size--it is somewhat heavy, but NOT for the range this lens has! I have been using a Sigma 70-200 f2.8 and a 2x teleconvertor, so this lens is a bit heavier, but the reach and sharpness do not compare! I use it hand held at F16 and 600mm and get sharp pictures. It does take some getting used to, but it is well worth the little effort it takes. Sigma nailed it for me with this lens!!

[Black] Quality and Price is good

[0.205 lb] Until I bought the Sigma 150-600mm Contemporary zoom, the standard lens I carried into the field was Nikon's 80-400 mm. The 10 Sigma 150-600 is nearly as light but oh so very much sharper. I have photographed everything from dragonflies and butterflies to wild turkeys and Rocky Mountain bighorn sheep with it. The lens produced sharp images of each and every subject. I would and have recommended this lens to friends and acquaintances.

[Black] This is an amazing lens for its price, it can be hand held but a tri or monopod makes life much easier. Focus is quiet and fast, the lens lock is great to prevent creep and when carrying. The only thing I would like would be a larger foot option
