Great long range lens for those who are trying to learn how to shoot photos long distance. Good lens for the price.I saw a review that someone gave on youtube before I purchased mine and he took the lens in his hand and shook in and pointed it out as a flaw in the lens. I'm glad I did not listen to him.I did the same thing when I received mine and I notice a little rattle, but thank God for my inspection and machining background, I realize the adapter base that comes with the lens wasn't tighten all the way down, which is no fault of the manufacture (Bower), but my own negligence and probably the negligence of the guy who did the youtube video. I hand tightened the adapter slightly, shook it a gain and I didn't hear anything, It was rock solid. Took some good shots of the 2017 solar eclipse. Good product,Good price.

Had high hopes, but this thing is entirely too sensitive on the focus ring and I have yet to get a crisp photo with it.

For the price, it's a cool toy to play with and try out long distance shots with your camera. It's really large, so it's not a lens you are going to just have in your bag just in case. This is a lens to pack for days you can spend time looking for long distance shots. It's pretty manual, and to be honest a little beyond my "know how" when it comes to lens. Nonetheless, it's fun to experiment with.

Awesome gadget , I know nothing about photography , but got this lens out and took a picture of about six doors away down the street and wow ig look like I took it from standing on his drive way , Got it for a large Graduation function where we will be seated quite aw sys from the graduate , this way I know I'm gonna get the pics I want now , and what a great price for so much fun , can't wait to. Picture the birds at the beach. On the rock at Morro bay ?

Poor photo quality. I knew it wasn't going to be professional quality but this is just horrible. It makes a better paper weight than it does camera lens.
