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.

It's alright (Read)
This is amazing for the price, but it lacks autofocus and has a somewhat pixelated image. You get what you pay for, and it's also pretty shaky, but still great.

Great price and quality
I'm a novice when it comes to photography, and I've never used a ridiculously expensive lens, so I can't speak to comparisons, but I love the shots I get with this one. A tripod is definitely a must use, and I don't have a remote, so I use the camera timer to let it settle down after pushing the button. I have a Canon R100, and it fit right up. With some time and effort in making those adjustments, I can say I'm fully satisfied with the results. Pictures are 2 at 800mm and one at 600mm

Amazing lens for amateur photographers!
This product is the most budget AND we'll made tele lens. DO NOT BUY IF... 1. You dont know how to manually adjust shutter speed and iso on your camera, because the aperture is tied directly into how far your zooming and it will not work on camera AUTOMATIC modes. But I have snapped some beatifull pictures with it.

KNOW WHAT YOU'RE BUYING!!!
A few things you should know before purchasing this lens. It is FULL MANUAL, it says that upfront in the instructions. That being said, there are NO PINS, nothing to connect the lens' functions to the camera, so adapters won't work. Make sure you get the proper version for your camera. For example, I got the Canon ef/ef-s mount. It works fine with my T5i, 7DII, and 5DIV. However, my M50 and R6 with ef/ef-s adapters do not allow the cameras to shoot because without adapter pins to properly allow the lens to communicate to the body, the camera thinks the lens is loose, and will not fire. UPDATE: If the camera setting "release shutter without lens" is on, this may allow the adapters to work, however, your aperture setting will still read f00. The fit is tight and secure however, so you just have to make sure you get the proper version of this lens for the body to which you want to attach it. That said, it is what it is. Its a $50 novelty lens that indeed gets you 400-800mm. Its basically a kid telescope that you can attach to a dslr. Good focus IS possible for sharp photos with patience and good settings. To a point. LOTS of light is needed. Remember, this is full manual so aperture shrinks as you move from 400 to 800. Wanna shoot astro? Just be ready to accept grainy photos because your ISO is going to have to be STELLAR (see what I did there?) There is no way around it, its just a slow lens. The adjustment rings are solid, tight and smooth, almost a bit too tight. I would not recommend using the foot to mount to a tripod if you have anything larger than an M50--the foot ring allows for rotational adjustment but just that. You cannot slide the ring to adjust for balance (Unless i missed something--seems to be slotted). But again--remember, youre not paying 2K+ for this. Its a novelty lens, good for telephoto kicks, or to see if yo need 800mm (assuming you can get your mind past the shortcomings). Its solid, doesnt feel like a cheap piece of plastic, like its going to fall apart. The optics aren't amazing, but again--50 bucks for an 800mm...

New Photographer on a budget? Worth the money spent!
I was looking for a longer range telephoto for my new Canon R100. Because I typically try and shoot manually, it hasn’t been a major inconvenience. Having a lens with Auto-Focus will be my next investment because if you do any type of birding or nature photography, the subject doesn’t typically stay still for long. My only negative mark for this lens so far is the zoom lock not really locking fully. Image quality is very good as you can see from the attached photos. Was well worth the money spent. Fit my Canon R100 with no issues.

Per il prezzo che costa è un buon obiettivo, il suo dovere lo fa. Buono lo zoom, basta impostare la modalità manuale e giocare molto con il focus. Non ho trovato particolari difficoltà nel montaggio e tutto corrisponde alla perfezione con macchina Nikon D7500. Lo sento un pochino "leggero" ma, per quello che ci devo fare va più che bene

Please note it is manual only -- move the camera dial to M, otherwise it will say lens not recognized; and manually select ISO and aperture if need be. It seems solidly built. The manual focus ring adjusts the focus very slowly, which means you have to turn it a lot but is good since you can get a good sharp visual focus. Pictures are sharp. If you want a budget lens that can capture targets hundreds of metres away close-up, this is it. This was on a Nikon D3300. Double-check compatibility before buying.

Il voit loin, Facile à mettre en place, la bague est déjà fixée sur le fut. Facile à monter sur un pied. Mise en place en cinq minutes et quelques essais. Premiers constats : Prévoir un déclencheur ou une télécommande (sinon flou de bougé). La bague de mise au point est simple à appréhender et à régler. À 800 mm, vous avez une frange autour du sujet. Il vaut mieux avoir un logiciel tel que Lightroom pour la supprimer. Dans son ensemble, c'est un objectif de qualité plutôt basse, mais qui donne quand même d'assez bons résultats. Rattrapable en post-traitement. Le piqué n'a rien d'exceptionnel, loin de là. Mais je pense qu'il peut vous apporter de bonnes photos que vous n'auriez pas pu saisir avec un objectif standard. Alors pour le prix, c'est à vous de voir

It has decent zoom but not a wide variety of distances within its limits. There a bit of a rainbow when zoomed in too much. A decent tripod is almost a necessity. Learning curve is steep, as it can be difficult to work with (may be the same for all zoom lenses), to zoom, focus and adjust settings on camera just to take one shot. All in all, it's a decent lens at a good price. Good to learn and practice with. Rating may be higher once I get better working with it....better results/pictures UPDATED: I've had a chance to better use the lense. The pictures it took were quite good, even without a tripod (but still...get one!). Im still working on using different zoom lenghts. Attached pics were taken "across the lake" For the price, it is likely what I will need. Rating has been increased accordingly.
