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. Review: Quality Lens - 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. ## 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.

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 really appreciated this lens for the convenient price. ### ⭐⭐⭐⭐ 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.us/products/655802114-420-800mm-mf-telephoto-lens-ef-lens-for-canon-dslr](https://www.desertcart.us/products/655802114-420-800mm-mf-telephoto-lens-ef-lens-for-canon-dslr) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-08-06*
