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.

Nice lens for the price. As with all telephoto lenses in this price range they do suffer from chromatic aberration. This is an easy fix by making an aperture filter ring to reduce the amount of light coming through the front of the lens. There are several YouTube videos on how to accomplish this.

Let's be clear, this is NOT a super high quality lens. However, at less than $100 this is a superb value. I have a Canon R50, and hooked this lens up via an EF-RF adapter, and everything worked as it should. I have been tossed up between getting an RF100-400 lens, or a Sigma 150-600, and I hop to use this 420-800 to help me determine whether a 400mm focal length is enough, or if I need the extra reach of a 600mm lens when looking for something with autofocus. That is my main purpose for using this lens, and afterwards, my wife can slap this on her Rebel T6. Observations 1. Image clarity - Image clarify is not great, especially at 800mm, but this isn't a $2,000 lens. I've attached two images. The one of the birds is at 800mm, and the one of the dog is somewhere in the 500-600mm range. This will get you an image, but nothing you're going to blow up and hang on your wall. 2. No stabilization - Unsurprisingly, there is no image stabilization. My Canon R50 also lacks image stabilization. I have found it NECESSARY to use a Bluetooth remote shutter (only a couple of bucks) and a tripod to get good results. I have not gotten good results trying to handheld shoot. At the long length, any touching of the camera can result in added blur. 3. Focusing - This does work fine with Canon's "MF Peaking Setting", which will show little red dots to indicate which part of the image is in focus. This makes it much easier to manually focus! 4. Lens focal length and adjustment - Adjusting the focal length of the lens is more like adjusting a spyglass telescope. There is a lock ring you loosen, and pull out the lens to increase the focal length. That being said, the lock ring doesn't fully lock down, you can still pull out the scope even if it's fully locked. The focal length itself (420-800) is quite hard to work with. At 420mm, it can be hard to find your subject, especially if it is a bird in a tree. A 150mm or even 200mm starting place would be much nicer. In doing some bird watching in the backyard, I put the camera on a fluid head tripod and that helped me to scan the trunk/branches of a tree to find the right branch with the bird on it. At less than $100, I wasn't expecting much. However, this is a perfectly useable lens for a hobbyist who wants something with a longer focal length and doesn't want to shell out thousands of dollars. I'd stick with using this in very bright conditions to maintain any clarity this lens does have. I've tried to lay out my observations and findings in using this lens to assist others, and some of the feedback may sound harsh, but I want to be clear that the image quality isn't great, but you do get a LONG lens for practically pennies.

As a photographer, I have worked with a variety of lenses, but this manual focus telephoto zoom lens offers a remarkable versatility at an unbeatable price point. Its 420-800mm range gave me the ability to shoot distant subjects with stunning clarity, making it perfect for wildlife photography, sports events, and even moon photography. Its sleek white finish adds a professional touch, complementing my Canon setup beautifully. The image quality this lens produces is truly impressive. Even at the 800mm mark, I noticed very little distortion, and the details remain crisp, especially in well-lit environments. It’s important to note that the manual focus feature might require a learning curve for those used to autofocus, but once you get the hang of it, the control it gives you over your shots is exceptional. I’ve been able to capture some breathtaking close-ups of birds and other wildlife, which would be difficult with a standard zoom lens. What I love most about this lens is its durability and build quality. Despite being priced affordably, this lens feels sturdy and well-constructed, able to handle various outdoor conditions. I’ve taken it on multiple hikes, and it has held up wonderfully, even in more rugged environments. The lens is also relatively lightweight for a telephoto, which is a big plus when you're carrying other equipment. Paired with a sturdy tripod, it can help you achieve some professional-grade shots without breaking the bank. Another great feature is its compatibility with a wide range of canon camera models. I’ve tested it on my Canon 90D, and it mounts perfectly on both. This lens is a great addition to any photographer’s toolkit, whether you're a beginner looking to expand your range or a more experienced photographer in need of a long-distance option. The versatility of this lens means you won’t need to swap between different focal lengths as often, making it ideal for on-the-go shoots. Overall, I’m thrilled with this lens as it delivers excellent performance at a fraction of the cost compared to other lenses in this category. If you’re looking for an affordable way to up your photography game, especially for long-distance subjects, this lens is a fantastic choice. Just be ready to put in some time with manual focusing – it’s well worth the effort!
