EF/EF-S 420-800mm F8.3 Telephoto Zoom Lens(MF) + T-Mount for Canon EOS Rebel T8i/T7i/T7/T6i/T5/T3i/T2i/XSi/SL3/SL2/T100/90D/80D/70D/50D/5D Mark IV/6D II/7D II/1D X III II - Manual DSLR Cameras Lenses

As pics show, these all shot at full 800mm. No tripod, all hand shots. It is going to add some bulk, but if you have good methods of holding telephoto lenses you know how to do it. I just got this today, and the quality is really nice for the 80 or so bucks spent. This resolves nicely on my D750 though it shows DX, and crops the image. It didn't state DX lens in the order details or description, but I assumed it would be. Full frame tele lenses just don't come with $80-100 price tags.Build quality is great too... again for the price. Focus ring is tight, and I like that. Most kit lenses DX lenses are on the loose focus ring side of things. Too easy to move. The lens cap is the weakest point. Spring was stuck. I can get another if needed. Not a big deal. This basically makes your camera look like a small telescope. The included T ring for the lens is nicely made. No issues, all metal and has 3 small allen screws for extra security to the lens mount. Comes with lens caps, faux leather case. Some chromatic aberration is to be expected, but overall if your subject is center, it's not bad. The flag picture above with the cloud background was shot at the full 800mm. The problem I had in my camera was not being able to set the Aperture. It fixed at F22. Auto ISO did well enough for most shots. I bought this to photo rocket launches as well. Great lens, awesome price!!! Not good in low light though, so don't expect much there. Should work better on a tripod for moon, or even bright planets. Going to try getting Jupiter and it's bigger moons.

Simple, honest review as to why I gave it five stars.Likes: price is unbeatable, seems to be well made out of metal not plastic, light weight, narrow design, excellent sharpness at 800mm for the priceDislikes: chromatic aberration is sinful, the screw on camera mount doesn’t stay tight, the tripod mount seems a little flimsy, not weather sealed, no aperture ring, no filter threads and the vinyl pouch is an abomination.This lens is excellent if you want to use it to survey an area from a long distance away, without spending the king’s fortune on a high dollar lens that weighs 16 lbs and is 5 ft long and 1 ft wide. A drone might work also but it’s not going to cost $66. That’s why I gave it five stars :) You might be disappointed if you’re a high priced photographer like myself, who sells his images for a living. This is not that kind of lens. Although I did get some sharp ones out of it.

I opened the box 10 min ago. The lens easily attached to my Canon Rebel using the provided T mount adapter. The hex tool also porvided was not needed. Its a manual focus lens so I had some concerns but I was able to focus the lens faster than my standard ef-s lenses set on auto focus. Picture quality is yet to be determined but the image on the cameras viewing screen is impressive. In my novice opinion this lens is worth twice the price.Another plus is I receved the lens in perfect condition 2 days early. When purchasing in the future I will be checking this companys lenses first.

The lens itself was impressive. I wasn't expecting much as it was pretty inexpensive, but my initial pictures were pretty good! Yes, using a tripod is needed unless you're very lucky. Yes, manual focus is a hassle, but that's the way it was in the old days so, suck it up - LOL! It still was well worth the cost - until the metal on the tripod mounting ring broke after only trying it out about 4 times in 6 months. Now, I cannot reliably mount the lens at all and I'm not going to risk my camera, hoping it will just stay. Because of the cheap steel they used, it's pretty much useless now.

You get what you pay for. It is an affordable alternative to name-brand lenses. The issue is, you have to be in manual mode to even use it, so you're constantly needing to adjust and readjust the lens to keep your subject clear. The output, once you look at the photos in post, shows soft, rounded edges and pixelation. So the lens really is just a piece of glass that doesn't entirely interface with your DSLR, resulting in less than top-quality photos. This lens shines best for night photography, capturing the moon or some distant wildlife. Again, you get what you pay for.

A little tricky to learn to manually focus but once you get used to it the lens is fantastic. Took it to Yosemite and could zoom in on the people up on half dome from across the valley. First picture is to show distance. Second picture it the tip of half dome

I am extremely pleased with this. For the price I was expecting something cheaply made, impossible to use. There was no way I could get good pictures, I thought.First off, it's very well constructed. Heavy, sturdy steel. The lenses seem crystal clear. It feels like a more expensive item. It's not some 3D printed, mass produced piece of crap. Definitely worth more than the price, as far as workmanship is concerned.Secondly, I was pleasantly surprised with the picture quality I got. Of course the first pictures I took were of the moon (like everyone else). You can actually see craters. The picture of the rabbit--that's from about 50 feet away, hand held, no tripod. You can see for yourself the color and the clarity.Now, this IS a manual lens. I'm using a Nikon D3200, very basic DSLR, set to MANUAL. After experimenting with different ISO's and shutter speeds, and some pictures that didn't turn out, I think I got the hang of it. For the moon picture I did have to mount it on a tripod and use the timer release to click the shot, to minimize blur. But you can get good pictures without a tripod for distances up to about 50 feet.Definitely worth the price. I wasn't quite ready to invest in a $3000-10,000 lens. This does what I need it to do.
