BENOISON Telephoto Lens RF Lens for Canon, 420-800mm Manual Focus MF Zoom Lens for Canon EOS R, Ra, RP, R3, R5, R5 C, R6, R6 Mark II, R7, R8, R10, R50, R100 Mirrorless

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 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.

Overall, the lens assembly seems well built and functionally sound. My biggest gripe and grounds for my poor review is a quality control issue. There are artifacts in my pictures that are clearly dirty lenses. After careful and thorough efforts, I conclude the dirt contamination is internal and one I cannot rectify. That is very disappointing since the lens is otherwise quite good optically with minimal loss of focus when changing zoom levels. This is an example where one detail in quality control can completely sour a customer's take on your product.

The product is good

-1. Picture focus was never clear - 2. After carefully following the instructions, camera still would not shoot/take pictures + 3. Lense construction is good for the price + 4. Get what you pay for - 5. Couldn't think of another positive comment

Good n Business!

The lense is very good clear easy to use

It dos fit my camera, however it will not work. since I didnt have the opportunity to use it until 10/4/25 my review is late. It will not take photos. I'm stuck with a lens that does not work.

Niente male inizialmente è un po' difficile da capire ma poi capisci che è una cavolata, per Canon R100

Very difficult to use. You most definitely need a good strong tripod.

Llegó en buen estado,buen embalaje, el objetivo con un trípode cumple bastante bien, no olvidemos su precio. solo lo he probado un par de veces fotografiando desde el balcón de casa y quedé satisfecho. En las fotos la distancia del pájaro es de unos 200 metros.

Leider für mich zu aufwendig, da alles manuell eingestellt werden muss. Kann daher von der Bildqualität nichts sagen. Es ging zurück

I read it would work with my canon eos r10 mirrorless digital camera N Nope it dont work then I googled about it N it says it isnt compatible with my camera. Ugh!!!
