420-800mm f/ 8.3 Manual Telephoto Zoom Lens + T-Mount for Canon EOS Rebel SL2 SL1 T3 T3i T4i T5 T5i T6 T6i T6s T7 T7i 4000D 6D 7D 60D 70D 77D 80D 5D II/III/IV 550D 650D SLR Camera Lenses

The product obviously is not the best and dont expect this to be at this price. However, I do see what the reviews are all about. All I can say is combining the lens plus CHAT GTP and you can really get the most out of it. Add your pictures to chat gpt and tell it to fix them. The outcome is amazing! I started at the park with my iphone, here comes the rest: Picture #1 to see how far these people were from my zoom lens. Picture #2 is the actual picture the camera took with the Jintu Lens Picture #3 is what Chat GPT generated after telling it to fix. Now you have an amazing picture and it worked for the rest of them For the price I've paid, It saved me hundreds of dollars. I use chat gpt a lot so I dont mind paying my subscription fee as I do a lot of research with it.

Definitely a great lens for the price! I can see where some people would be coming from with the blurriness but it’s really only noticeable if you don’t have a tripod or if it’s not in TV/Manual mode. It takes really nice photos when it is in those modes. I found it easy to hook up for the most part with the instructions provided. It fit the camera. Little bit heavy but again that’s why you use the tripod. Overall very neat! I’ll have to play around with it more. Update with more photos: this lens is fantastic!! I can’t believe the photos it takes now that I’ve gotten used to it. But the lens!!!

I used this for the recent solar eclipse, since I didn't want to shell out thousands for a fancy lens or rent. Pros: This lens is SHARP. And the magnification is great. It does what it says on the tin. Superlightweight. You probably don't need to use the stabilizing foot. Cons: Strong chromatic abberation, esp around the edges. Better when zoomed in. Low contrast, esp when flaring. Fixed Iris! - f8 at 400mm and f16 at 800mm - Weird, distinct, heavy flares with very bright lights. Now in my posted sample, I also had a variable ND filter which adds to the coloring of the flare pattern and gives it the wonky + shape. When your light source is controlled the flare acts like haze as seen in the thinnest crescent. Very nice, reminds me of old lenses and film stock. Honestly, it's a specialty lens that I'll use whenever I need a telescope, and the price is exactly right, maybe even great.

Like most have said it is difficult to have it fully extended without using a tripod or monopod, but I have been using this lens for about a month now and for the price you really can’t beat it. Like others have said it sucks in lowlight but is ideal for full daylight or for partial cloud covered days. I have been using this lens primarily for all my birding photos lately and tried it out at the San Diego Safari Park as well. The sweet spot for not using a tri or monopod is the 420-600 mm range, but if you use it often enough you can get great shots without a tri or monipod. All these photos are without using either. The focus takes a second to get used to as it has a fixed arpeture and smaller section to view through but once you use it enough it is a really great cheap lens. Its also much lighter than most lenses that reach 800mm. The Red-tailed hawk photo was taken at full extension of 800mm.

For the price it's a great lens, especially if you know what you're doing with all the settings. Once I got things in focus, the obligatory pictures of the moon came out pretty good (image attached is on full auto with manual focus). That being said, I'm very disappointed in the tripod mount. I had set everything up, and had the lens mounted on the tripod. It was nicely balanced with the camera at that point. However, when I used the tripod arm to adjust the camera to point up higher to actually get the moon the weight from the camera caused the tripod mount to break. I'm grateful that I was able to catch the camera. With the busted mount, the lens is now fairly useless outside of a "throw it in the trunk for random art shots on a road trip" kind of lens.

This is a manual lens, which you should think of more as a telescope that happens to attach to your camera: -It does not have a shutter. -It does not have an automatic aperature. The aperature is a function of its shape and size, which is 8 at 420mm and 16 at 800mm, and varies in between. You need to set your camera to manual mode, then control the shutter speed (which is a digital shutter) and the ISO number (the sensitivity of the "film"). You can use the metering of the camera to find the correct exposure setting, which usually shows numbers going from -3 to +3, with zero being the nominal setting. If you are looking for a fully automatic lens, please go elsewhere and bring a lot of cash. I will be using it to capture the upcoming eclipse, so for those unfamiliar with FoV, cropped-sensor, etc. look at the photos for size reference. These were taken with Canon T7i at 700, 800mm, and 600mm respectively (I am unable to control the order of the photos). Also, the lens was covered with a Celestron Universal Eclipse filter, where the mounting-straps got in the way of taking 420mm photos, which is fine for my purposes.

Doesn’t work after like 5 uses. Doesn’t connect anymore!!!! I bought this last year and used it maybe 5 times, and now the piece that connects to the camera doesn’t stay on the telephoto lens so I can’t use! NOT A HAPPY CUSTOMER!

Who says you have to spends thousands on lense.. This works just as well as Brand names.. Starting out or even as a hobby this lense works great...

What a great lens it is clear and powerful. zooms very well. I was really impressed with the quality for such a good price. This lens is worth it. The pictures came out great. They even sent instructions on how to use manual mode and change the shutter speed on your camera. That was above and beyond great service of them. This is a manual lens. There are no electrical connections. You must adjust the zoom and focus yourself and then you must adjust the exposure on the camera yourself. It is an easy process and jintu Made the process even easier. This product is very well-made. I recommend this lens and would buy it again.

The lens is entirely manual. It is hard to get focus right, and most of the time, I just couldn't get the picture I want, but I still recommend it. I got it because I love taking pictures of wild birds, and they do not let me approach. The focus is hard to get, and the picture quality is not good (I recommend adjusting your light meter a little darker, -1 or -2, than precisely in the middle,0). The lens gets bleached when adjusted in the proper light meter. So taking a darker picture, you can get more information to correct it on photoshop or lightroom. For all the images I got, I had to correct the colour (vibration) in photoshop or lightroom. I am fully aware that a good lens with this configuration would cost me at least a thousand dollars, so let's be realistic here that it does a great job for the price. You have to learn how to focus manually. All these pictures were taken with the lens and without a tripod. I lean against something to give me stability and also hold my breath. It would help if you also used your ISO to get faster-shot speed. It is working well for me, and being honest. I am getting better and better at manually focusing the pictures now. I strongly recommend it for those who want to have some fun and practice manually focusing. Observation: The lens already comes with tripod support in the middle, so you do not need to worry about buying a ring to fit it on the tripod. The zoom is crazily far, and you can get nice shots.

Very surprised with the product! It’s sturdy, easy to setup and use. Can’t wait to use it more in the near future. The first thing I did when I got it was to take a picture of the moon. I find it very good for the price! I used it more since and took nice birds pictures using it! :)

My expectations weren't high when I bought this thing but I was quite amazed after receiving it and using it with my Canon T3 camera. I used it for taking photos of the Moon and for that purpose it's suited by needs very well until I could afford to upgrade to a dedicated Optical tube assembly for that purpose. If you know how to manually focus the lens then this is the perfect budget lens to achieve the level of Zoom that other lenses will charge you $500 to $1,000 for it.

I have tried in so many different environments, and the lens just sucked. I really wanted it to work. It only ever disappointed, unfortunately.
