BENOISON Telephoto Lens for Canon - EF Lens 420-800mm for Canon DSLR, Manual Focus MF Zoom Lens for Canon EOS Rebel SL3 SL2 SL1 T8i T7i T7 T6 4000D 1500D 90D 80D 77D 70D 60D 7D 6D 5D 1D DSLR

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.

So it's very cheap for a giant lens, and I'd say get it if you don't already have a long zoom and don't plan to pay 10x for a good one.They aren't the greatest lenses. Not super sharp and lots of color fringe. NOT BAD FOR THE PRICE, but not great.The main reason it doesn't do much for me is because the overall finished output with this low end zoom lens, matched to a good R100 body, is very similar to the quality of pictures I get with an older Panasonic bridge model. Good lens + mini sensor holds up very well against a good APS-C sensor with a bargain lens. And the bridge camera has image stabilizing and auto focus for a very convenient shooting experience.However, if you don't already have an old-but-good super zoom bridge camera sitting around, you can't just go get one for this price. So factor in all of that. It's going to be one of the cheapest lenses you buy for a mirrorless camera, and it does provide a function you can't get easily otherwise.

Works well with my Nikon D3300Takes clear pictures.Price is affordable and fast shipping from seller. Will be origin from seller.

Not compatible with my camera. Going to return soon.

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.

Narrows picture to much

I was a little skeptical about purchasing this lens but I must say I love it I use it with a canon EOS 4000D the quality is great image quality is great keep in mind there’s no autofocus this is a manual lens it’s a bit heavy if you have a steady hand great if not I suggest using a tripod other than that it’s very easy to use

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.
