Style: For Canon EF/EF-S (Black)
Great lens for the price. Only downside is that it is fully manual and not able to do autofocus. This makes it hard to capture birds in flight and get detailed photos. But for still instances, it works well with expertise and practice. Here are some of the pictures I have taken with it. I have had this lens for a year now, now upgrading to a Sigma 150-600 mm lens for the Autofocus capabilities. I really appreciated this lens for the convenient price.

This is amazing for the price, but it lacks autofocus and has a somewhat pixelated image. You get what you pay for, and it's also pretty shaky, but still great.

I'm a novice when it comes to photography, and I've never used a ridiculously expensive lens, so I can't speak to comparisons, but I love the shots I get with this one. A tripod is definitely a must use, and I don't have a remote, so I use the camera timer to let it settle down after pushing the button. I have a Canon R100, and it fit right up. With some time and effort in making those adjustments, I can say I'm fully satisfied with the results. Pictures are 2 at 800mm and one at 600mm

I was wary about using a non-brand-name lens with my Canon DSLR, but this lens is great. It does not interface with the auto-focus on the camera, so it's manual-focus only, and you have to manually adjust fstop and aperture, but that's kinda the point with a DSLR anyway -- ultimate control over exposure. My only caution is that because it does not have image stabilization use a tripod and a timer to take your pictures. This is not a lens for action shots! By using the timer, you give the camera a few seconds to settle down after pressing the shutter release. (I suppose you could also use a remote shutter release, but I don't have one of those.) The price point was excellent which is what made me decide to try this lens. It comes packaged in its own protective sleeve with a place to mount the lens to your tripod which helps make it more stable.

A few things you should know before purchasing this lens. It is FULL MANUAL, it says that upfront in the instructions. That being said, there are NO PINS, nothing to connect the lens' functions to the camera, so adapters won't work. Make sure you get the proper version for your camera. For example, I got the Canon ef/ef-s mount. It works fine with my T5i, 7DII, and 5DIV. However, my M50 and R6 with ef/ef-s adapters do not allow the cameras to shoot because without adapter pins to properly allow the lens to communicate to the body, the camera thinks the lens is loose, and will not fire. UPDATE: If the camera setting "release shutter without lens" is on, this may allow the adapters to work, however, your aperture setting will still read f00. The fit is tight and secure however, so you just have to make sure you get the proper version of this lens for the body to which you want to attach it. That said, it is what it is. Its a $50 novelty lens that indeed gets you 400-800mm. Its basically a kid telescope that you can attach to a dslr. Good focus IS possible for sharp photos with patience and good settings. To a point. LOTS of light is needed. Remember, this is full manual so aperture shrinks as you move from 400 to 800. Wanna shoot astro? Just be ready to accept grainy photos because your ISO is going to have to be STELLAR (see what I did there?) There is no way around it, its just a slow lens. The adjustment rings are solid, tight and smooth, almost a bit too tight. I would not recommend using the foot to mount to a tripod if you have anything larger than an M50--the foot ring allows for rotational adjustment but just that. You cannot slide the ring to adjust for balance (Unless i missed something--seems to be slotted). But again--remember, youre not paying 2K+ for this. Its a novelty lens, good for telephoto kicks, or to see if yo need 800mm (assuming you can get your mind past the shortcomings). Its solid, doesnt feel like a cheap piece of plastic, like its going to fall apart. The optics aren't amazing, but again--50 bucks for an 800mm...

Very happy with my purchase. I bought this to take on a cruise to Alaska. I found that it works best on "Sports" mode and it's not for taking quick shots. The manual focus lens is better suited for taking still shots with some type of stability. Easy to attach and detach. Construction seems to be quality. Not overly heavy, but not lite either. I'm looking forward to my next trip so I can use it again.

I was looking for a longer range telephoto for my new Canon R100. Because I typically try and shoot manually, it hasn’t been a major inconvenience. Having a lens with Auto-Focus will be my next investment because if you do any type of birding or nature photography, the subject doesn’t typically stay still for long. My only negative mark for this lens so far is the zoom lock not really locking fully. Image quality is very good as you can see from the attached photos. Was well worth the money spent. Fit my Canon R100 with no issues.
