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

It is a $50 800mm lens that works. It might not have autofocus or image stabilization, but a canon 800 mm lens would cost over $1000 dollars. I imagine that Canon lens is worth every penny, but this $50 lens It is a good way to dabble in such a long lens without the full commitment.

Solid lens for the price. I would suggest using a tripod, but you can use it effectively without one. This lens is definitely light hungry due to the aperture so sunny days and a higher iso is recommended. The two pics of the train tracks were taken in the same spot to compare the minimum and maximum zoom. The box car was at least 300 feet from where I was standing.

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.

Make sure you have a tripod...no matter how steady you think you are. Great photos, non the less...would buy it over again.

The connector from the lens / barrel that attaches it to my camera broke off. Sent several messages to seller to get a replacement but haven’t heard anything yet. Images weee good with the lens when I was able to use it. Manual focus was tricky to learn but I figured it out.

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.

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...

For the price it is unbeatable. I get that a 500-10,000 lens is going to be infinitely better with stabilization, autofocus, clarity, aperture control, and all the other bella and whistles. That being said, if your choice is between this or no zoom lens because you cannot afford the expensive toys, this is awesome and you can really get decent pictures and get to really know the basics with it.

Muy buen artículo

Ich muss sagen ich bin positiv überrascht, ja die Verarbeitung ist jetzt nicht die deutsche Din Norm, aber es ist für den Preis absolut großartig, man muss es alles ordentlich festdrehen und braucht ein wackelfreies Stativ, aber für Mondfotos als Beispiel ist es sehr gut geeignet, auch für Tierfotografie im Park wobei es dafür wirklich hell sein muss

Degelijk , ziet er goed uit

It has decent zoom but not a wide variety of distances within its limits. There a bit of a rainbow when zoomed in too much. A decent tripod is almost a necessity. Learning curve is steep, as it can be difficult to work with (may be the same for all zoom lenses), to zoom, focus and adjust settings on camera just to take one shot. All in all, it's a decent lens at a good price. Good to learn and practice with. Rating may be higher once I get better working with it....better results/pictures UPDATED: I've had a chance to better use the lense. The pictures it took were quite good, even without a tripod (but still...get one!). Im still working on using different zoom lenghts. Attached pics were taken "across the lake" For the price, it is likely what I will need. Rating has been increased accordingly.

Really pleased with this zoom lens does a great job. Great price quality product.
