Review: 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.
Review: 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
*by G***L on December 4, 2025*

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.
