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 Review: New Photographer on a budget? Worth the money spent! - 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. ## Features - 【Super Telephoto Lens】Manual focus telephoto lens, NOT original-lens, a focal length of 420-800mm and an aperture of F/8.3-16 (non-adjustable aperture value, f8.3 at 420mm and f16 at 800mm), filter size of 62mm, full frame, RF mount, built with high-quality materials and robust construction, making them durable and long-lasting; - 【RF Lens for Canon R Series Mirrorless Camera】420-800mm Manual Telephoto Lens Compatible for Canon EOS R, Ra, RP, R3, R5, R5 C, R6, R6 Mark II, R7, R8, R10, R50, R100 Mirrorless Camera (Not for Canon M series Mirrorless); - 【Upgraded Version】Upgraded into an RF mount, which can be mounted on Canon mirrorless cameras without connecting the T adapter ring. For those who photograph wildlife or the moon as a hobby, this lens would be a great choice; - 【User Instraction】This is a FULL MANUAL lens, NO Electronic Contacts, your camera will not allow to press the shutter after the lens is mounted, please set the "Release shutter w/o Lens" option in the camera menu to "Enable". Tips to use our Manual Lens: 1) Set the Release shutter w/o Lens option in the camera menu to Enable. 2) Set the mode dial to Manual (M); - 【Manual Focus】The lens has a focus ring located near the front. Manually rotate this focus ring to adjust the focus. Turn the ring slowly until the subject you want to focus on appears sharp and clear.

Need to turn the focus ring (on the front of the lens) for manual focusing. If it is still blurry, use a tripod and time-lapse function to keep the image stable. **Q: Why is F00 displayed and how can the aperture value be set?** A: As the manual lens has no electronic contacts to recognize the aperture value, “F00” is displayed. The aperture value can only be adjusted automatically by changing the focal length. (420mm/F8.3 →500mm/F10→600mm/F12→700mm/F14→800mm/F16) **Q: What if the image turn out bright?** A: If the image is too bright, lower the ISO (e.g. from 200 to 100) to reduce the light sensitivity and increase the shutter speed (e.g. from 1/125s to 1/250s) to reduce the exposure and avoid overexposure. **Q: What if the image turn out dark?** A: If the image is too dark, increase the ISO (e.g. from 800 to 1600) to increase the sensitivity and decrease the shutter speed (e.g. from 1/250s to 1/125s) to allow more light onto the sensor. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great price and quality *by R***G on December 5, 2025* 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.

Worth the money spent! *by J***S on May 28, 2025* 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.

Fit my Canon R100 with no issues. ### ⭐ Good product, poor quality control. *by J***E on May 4, 2026* 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. ## Frequently Bought Together - BENOISON Telephoto Lens for Canon - RF Lens 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 - Altura Photo 58MM Tulip Flower Lens Hood for Canon EOS 77D 80D 90D Rebel T8i T7 T7i T6i T6s T6 SL2 SL3 DSLR Cameras with Canon EF-S 18-55mm f/3.5-5.6 is Lens and Select Nikon Lenses - Ultra Deluxe Lens Kit for Canon Rebel T3, T5, T5i, T6, T6i, T7, T7i, EOS 80D, EOS 77D Cameras with Canon EF-S 18-55mm is II Lens - Includes: 7pc 58mm Filter Set + 58mm Wide Angle and Telephoto Lens --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/701936838-benoison-telephoto-lens-rf-lens-for-canon-420-800mm-manual](https://www.desertcart.hr/products/701936838-benoison-telephoto-lens-rf-lens-for-canon-420-800mm-manual) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-08-23*
