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.

Definitely one of those you get what you pay for items. Every long distance shot I’ve taken has come out not so clear due to chromatic aberration. Close or rather the 400 mm to roughly 600 mm range not bad at all. I will say it captured the moon pretty decent. Although I’d strongly suggest using the timer function on the camera or a shutter remote to get the best shot possible.

This is nice for the price. It connects easily. It zooms really well. It has no autofocus, but at this price I wouldn’t expect that. It’s built well and it works great.

We tried using this lens on our Nikon and it was not working on our camera. It was telling us the lens was not attached and it was. When I took a photo it was completely white. Unfortunately I waited to use it after the return window was closed.

It is a very good toy! Fun to play with!

I only drag out a lens of this focal length occasionally, so I can't justify $500+ for a good name brand lens. This lens is perfect for my occasional nature or astrophotography. I have to strongly recommend the seller. I tried to use the first lens I received well after the Amazon return window ended for it. There was a big problem with the EF mount for the Canon. It would not turn and lock in. The lugs of the lens would insert into the camera body but something was machined in the lens' mount that blocked it from turning. I posted a review describing the issue. Less than a week later the seller contacted me and eventually offered a replacement lens. The new lens works fine. Attached is a photo of the blood moon of 3/14/25. There is no automatic focus or exposure and the lens is fixed aperture. I find that aperture priority auto, or full manual mode, works best.

Es bueno el producto

Value goes with price, I feel issues are manufacturing issues and seller made contact to resolve issues, would recommend seller
