Review: Great lens - 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. Review: Great for the price - This is nice for the price. It connects easily. It zooms really well. It has no autofocus, but at this price I wouldn’t expect that. It’s built well and it works great. ## 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 | B0DCW43DJ6 | | Best Sellers Rank | #17 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 | White | | 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 | 3.8 out of 5 stars 101 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-W-EF | | Maximum Aperture | 8.3 f | | Maximum Focal Length | 800 Millimeters | | Media Type | ProductImage | | Minimum Aperture | 16 f | | Minimum Focal Length | 420 Millimeters | | Model Name | BENOISON 420-800mm Telephoto Lens for Canon EF | | Photo Filter Size | 62 Millimeters | | Real Angle Of View | 5 Degrees | | Warranty Description | 1 year | | Water Resistance Level | Not Water Resistant | | Zoom Ratio | 1.9:1 | ## 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 ![420-800mm Telephoto Lens EF Lens for Canon, 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 Cameras - Image 1](https://m.media-amazon.com/images/I/617kGIApQwL.jpg) ## Available Options This product comes in different **Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great lens *by P***L on May 1, 2025* I was wary about using a non-brand-name lens with my Canon DSLR, but this lens is great.
