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. Review: Quality Lens at a great price - 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. ## 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, EF/EF-S mount, built with high-quality materials and robust construction, making them durable and long-lasting; - [Upgraded Version] Upgraded into an EF/EF-S mount, which can be mounted on Canon DSLR 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; - [EF/EF-S Mount Compatibility] Compatible with Canon EOS-1D Series, EOS-5D Series, EOS-6D Series, EOS-7D Series, EOS-10D to 90D Series, Rebel SL3 SL2 SL1(250D 200D 100D), Kiss/Rebel Series(Rebel T8i/850D T7i/800D T7/2000D T6/1300D T6s/760D T6i/750D T5i/700D T5/1200D T4i/650D T3i/600D T3/1100D T2i/550D T1i/500D) 4000D 3000D 1500D etc DSLR cameras. Not for camera M-series and R-series mirrorless cameras; - [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; - [NO electronic contacts and No Autofocus Motor] Manual lenses lack electronic contacts, so you need to use our lens in Mode M. On manual lenses, the camera may display F00 because it doesn't have direct access to the aperture value. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0DCW3DMT2 | | Best Sellers Rank | #34 in SLR Camera Lenses | | Brand | BENOISON | | Built-In Media | Lens Cleaning Cloth, Telephoto Lens, User Manual | | Camera Lens | Manual focus 420-800mm telephoto lens | | Camera Lens Description | Manual focus 420-800mm telephoto lens | | Color | Black | | Compatible Camera Models | for Canon 10D-90D Series, for Canon 1D/5D/6D/7D Series, for Canon 40000D 3000D 1500D Series, for Canon Rebel Series | | Compatible Camera Mount | Canon EF, Canon EF-S | | Compatible Devices | for Canon EF/EF-S mount DSLR cameras | | Compatible Mountings | Canon EF, Canon EF-S | | Customer Reviews | 4.3 out of 5 stars 286 Reviews | | Exposure Control Type | Manual | | Focal Length Description | 420-800mm | | Focus Type | Manual Focus | | Image stabilization | No image stabilization | | Lens | Telephoto | | Lens Design | Zoom | | Lens Fixed Focal Length | 420 Millimeters | | Lens Mount | Canon EF, Canon EF-S | | Lens Type | Telephoto | | Manufacturer | BENOISON | | Manufacturer Part Number | 420C-B-EF | | Maximum Aperture | 8.3 f | | Maximum Focal Length | 800 Millimeters | | Media Type | ProductImage | | Minimum Aperture | 16 f | | Minimum Focal Length | 420 Millimeters | | Photo Filter Size | 62 Millimeters | | Real Angle Of View | 5 Degrees | | Warranty Description | 1 year | | Water Resistance Level | Not Water Resistant | | Zoom Ratio | 1: 1.9 | ## Product Details - **Brand:** BENOISON - **Camera Lens Description:** Manual focus 420-800mm telephoto lens - **Compatible Mountings:** Canon EF, Canon EF-S - **Focal Length Description:** 420-800mm - **Lens Type:** Telephoto ## Images ![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 - Image 1](https://m.media-amazon.com/images/I/61S-7kV92YL.jpg) ## Available Options This product comes in different **Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Quality Lens *by P***R on January 1, 2026* Great lens for the price.

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. ### ⭐⭐⭐⭐ Excellent value for a budget lens *by M***R on March 14, 2025* 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. ## Frequently Bought Together - 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 - Endurax 60'' Camera Tripod Camera Stand for Canon Rebel Eos Nikon DSLR, Travel Tripods for Phone Tablet with Remote Black - SanDisk 128GB Extreme PRO SDXC UHS-I Memory Card - C10, U3, V30, 4K UHD, SD Card - SDSDXXD-128G-GN4IN --- ## 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.vn/products/655802114-benoison-telephoto-lens-for-canon-ef-lens-420-800mm-canon](https://www.desertcart.vn/products/655802114-benoison-telephoto-lens-for-canon-ef-lens-420-800mm-canon) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-05-13*
