JINTU 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

I paid $65 for this lens with a coupon from the product page, and I must say, it surpassed my expectations. I shoot occasional backyard birds for fun and used it on a Canon T4i body to take the attached shots. Shot in RAW format at 800mm, f/16, /1250 sec, ISO 1250, and cleaned up minimally in Lightroom Classic afterwards. Also attached is the same scene taken at 300mm with another camera. All three pics have not been cropped, they are dimension-wise as they came out of the camera. One thing that surprised me is how granular the focusing is. It shifts focus VERY gradually, which I guess is required for proper focusing at the 800mm end. The lens mates with the camera solidly and there's no wriggle. For me it's a keeper, it's a fun little lens to have in my bag to whip out for those occasions when the reach comes in handy (backyard bird watching, full moon, etc.). Don't pixel-peep and zoom in at 100% or greater to see all the flaws--they are there! Just enjoy it for what it provides at such low cost.

It is a great great product for someone who’s looking to work with zooming on animals, mother nature, or etc. although as a first starter photographer that I’m still learning my way around, I had to return it! Like I mentioned, it is a great product, but I’m not ready on how to use it. And the price is not bad a lot of people say that it’s too blurry, but you do need a stand to get a great capture. It is amazing how much you can zoom in.

Before and after editing pictured. I bought a cheaper lens because I typically only shoot daytime and wanted to try some basic astrophotography. Boy, this was a good investment. This thing is a chromatic aberration machine, however defringing is easy (when on a computer). The only reason I gave it 4 stars instead of five is because it’s probably not beginner friendly if you wanted to shoot in JPEG. I would only shoot in raw using this to make sure when correcting the chromatic aberrations that it doesn’t look wonky. And it still might, somewhat but for what it costs and the result you can get from it, you can’t really beat it. You definitely need a tripod to shoot with this unless you just have an unnervingly steady hand. For my Canon R model friends, get an adapter mount. This fits an EF mount so I bought an adapter that fits onto my canon eos R50 and mounts the EF lens onto it, works like a charm. For those of you that don’t know why it’s not taking photos automatically, look to the release shutter without lens setting. Sometimes the camera won’t communicate with the lens, especially with an adapter so this will allow you to release the shutter! Overall: Great lens for the cost, I wouldn’t shoot anything fast moving inside with this, you may get away with some animals but you will need a tripod/monopod since the image stabilization is nonexistent. This is a lens you need to correct for in post, so shoot in raw and bring it into camera raw or Lightroom to defringe it. Good luck!

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.

Why did you pick this product vs others?: For the price this lens has been great for me. I love to take birds photos and moon photos. I have a Canon Rebel with 300mm zoom, but I wanted something stronger. I didn't want to spend thousands of dollars at the moment. The focusing and lighting takes some practice, and I'm still working on that. It is much better than I expected. Assembly was very simple. I've not used it on my tripod yet. If the sky will ever clear, I'm excited to try a moon shot.

I am concerned over the ring adapter that came with item for attaching toy camera. First instruction was to tighten the three screws and with the provided allen wrench on the ring connector. But the screws appear to be either cross threaded or stripped and would not tighten any further onto the ring. When screwed in, the weight of the lens begins to separate the two pieces of the adapter. I'm afraid that it will become completely separated and break the lens. I've tried a different allen wrench set without success. I think it's best to return the item

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.

Be realistic. It’s shaky. It’s not perfectly sharp. There’s significant aberration. Contrast takes a hit. But it’s ABSOLUTELY INCREDIBLE VALUE. With a bit of post processing and some bumped up sharpness and contrast photos will look great. Would not hesitate to recommend this lens to anyone.

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! :)

This item looks great but it came with the wrong T mount so I had to place another order for it which will not get to me till mid Nov./Dec. So I have this lens that I can not try or use till the new T mount arrives I really hope it will be what I was looking for from this lens . That is the only reason I rated it so low at this time.
