Bigger and heavier than I expected, but the image quality is fantastic. Images come out super sharp and crisp and won't leave you disappointed. Autofocus is lightening fast in most cases, and even if it has to cycle through the whole range, it's still pretty quick. The focus ring feels smooth, and is easy to use, and has full-time manual override. Optical stabilization works well. I found the focal ring to be very stiff to use to the point where I wondered if the lock switch even had any purpose. It has loosened up a bit with use, but it's still stiff compared to my Nikon lenses. The case it comes with is very nice, and great for keeping the lens protected when not in use. Also the strap is very handy. Due to the weight of this lens, you really don't want to be carrying it by the camera body. A monopod or sturdy tripod with all-metal head is essentially required for most practical uses of this lens.

(Review wouldn’t let me use full resolution photos) I love this lens, I’ve gotten some shots I’m really proud of with it. I think this lens is the best bang for the buck, I have a Nikon d750 and I didn’t want to pay the extra money for Nikon 100-500 which yes having 5.6 at 500mm would be nice but often I’m not missing it. Plus the extra 100mm is really nice when you’re trying to learn how to get closer to your subject and you just want those nice up close shots. Is it perfect all the time? No it could focus faster for sure sometimes hunts but even the best lenses and best autofocus you have to shoot right to capture and focus really quickly. I definitely recommend this lens to people when they are trying to get into wildlife photography. If you have crop sensor and want lighter you could look at sigmas 100-400 my dad has that on a z50 and loves it Pros: -gets you closer to subject for a good value -feels pretty durable(even though I baby it) -you can get protective cushion skins and rain covers for it -you can get some really sharp photos -again great price comparatively -has image stabilization -comes with a nice tripod foot, smooth for rotating on tripod from portrait to horizontal Cons: -it’s pretty heavy but not crazy, if you’re going to be waiting for a subject in the bushes like I do sometimes I definitely suggest a tripod and a gimbal head. -probably won’t fit in most beginners camera bags but that’s to be expected

This is a great lens for those of us who can't spend thousands of dollars on one lens. My wife sat out in the backyard the other day and got some great up-close shots of butterflys without needing a macro lens. She was able to use the lens without a tripod. The shots I posted were at the lake just as the sun was coming up.

Matched with Nikon D5600. The pictures talk by themselves. Can imagine when I get the Nikon D850 for great results.

I would tell anyone to buy it that loves photograhy.
