Really nice lens for the money
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.

Awesome budget lens
First thing to keep in mind: this is a 67 dollar lens. Pros: This lens offers great zoom at 67 dollars Sturdy(except of the lens holder, it scares me for being tad bit loose) Nice quality(for a 67 dollar lens) Cons: Chromatics was horrible(easy fix though from photoshop) Manual(it is okay but will be hard for beginners) I fully recommend this if you are going on a budget in exploration of photography like me. Highly recommend the lens. A tip for the company: make the ring holder sturdier. If you are a professional and a whale, I would skip this and buy an expensive one from Sigma/other big companies.

Works ok
Mine has some dust inside, but does work, is pretty dark, has a large blue flare in the middle of the frame, kneeds a lot of light but decently clear and a great value.

Adapter listed but not included?
Well that's unfortunate. Similar to other reviews, my lens did not come with the adapter that it stated would come with it. I ordered the lens with an adapter for Sony e mount. I currently have no way to test this to see if it works. If I receive the appropriate e mount t adapter, I will update this review. Otherwise, this might just get returned.

Faulty lens, might have been a return
One the package seemed like it was open before. Two it wasnt delivered the day it was supposed, it wasn't even shipped by the delivery date Three when you put on the lens it's fine, fit good and shows the live image good, but after clicking to take the picture, there's black shade that's add out of nowhere. The last image shows the black shade. The image before that is the live view. Not sure what can cause that. I'm guessing, whoever sent out the product just picked out a returned item, not checking to see if it was faulty. I was definitely excited to use the lens, and I'll keep the lens because it still good for the price. Just wish the company was not sending out returned or damaged item just because they didn't have good ones in stock

T2 adapter.
I didn't use the lens yet because it didn't come with the T2 adapter as mentioned. I couldn't check the quality of the lens Edit The lens quality after use is verygood, the photos are beautiful. The shop ontacted me to resend the t2 adapter. They are very helpful. The shipping time is on time and fast as expected. Thanks Lightdow for the reply and the follow up. I re ommend the seller.

Fairly Decent for the Price.
For the price, it does the job. Manual focus kind of sucks, but that's expected for the price.

This lens has a purpose
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 price Dislikes: 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.

For this price, this lens is amazing. Here it is attached to a Canon EOS Rebel. The photos uploaded include both lenses that came with the camera and the new zoom lens on full zoom. The hardest thing is keeping the camera still, so I use a tripod. I recommend this product.

L'obbiettivo sembra perfetto e ben funzionante...sono io che devo ancora imparare a usare la mia canon!credo sia ottimo per fare esperienza!

Ich habe das mit meinem Canon EOS ausprobiert. Zoom und einstellen ist sehr leicht. Da Autofokus deaktiviert ist, muss man manuell fokussieren aber gar nicht schwer. AV, TV und Manuel Bedienung funktioniert einwandfrei. Automatik Modus bringt nichts, da objektif nicht elektronisch gesteuert ist.
