Ultimaxx 420-800mm (840-1600) HD Telephoto Zoom Lens for Canon EOS 90D, 80D 77D, 70D, 5D Mark IV, 6D Mark II, 7D Mark II DSLR Cameras & Rebel T7i, T7s, T7, T6s, T6i, T6, SL3, SL2 Digital SLR Cameras

Product is exactly as described. Fits my Canon Mark IV with the included adapter. I have been spoiled to my smaller lenses that auto focus, but want to learn to take photos manually, and from farther out. I definitely had to pull out my tripod for these. The first few I tried to take were blurry since my hand isn’t super steady. Once I pulled the tripod out they got a lot better. Excited to take this further than my backyard and even more excited I can learn on something that cost less than $100 before I decide to graduate to something more expensive.

Got the same. Nice original packing and it has lens, converter and also t-mount. Fits perfectly fine with my Canon 3000d dslr. It needs manual focusing but worth the buy considering the cost. Ultimaxxusa is US based company and they also respond to customers support queries.

I was looking to include a more powerful zoom lens with my collection, and this was a good option to test what use such a capability would be to me, without being overly expensive. This build quality in general is certainly good, and the EF-mount fits my Canon nicely. Being manual focus and zoom was not an issue for me, and after getting a different T-mount adapter, I can use the same lens on my manual 35mm camera, increasing its versatility. Image quality at full zoom is not as fine as more expensive OEM lenses, but that's to be expected for the price. The use of plastic for the tripod mount assembly makes it a bit wobbly at full zoom, making a remote shutter pretty much necessary for steady shots. Still, very useful if you want to try your hand with zoom on a budget.

Not for astro photography. Does not get better zoom than EF75-300, so while it does provide telephoto zooming capabilities, it's not better, or rather easier to manipulate than a standard EF75-300.

This is exactly what I needed!
