Fantastic quality for a manual zoom and focus
I was skeptical, even after seeing the photos others sent. Color me surprised though. Let's face it: you're looking at this because you want to take lunar pictures. Maybe even planets! I'll say that I don't think this has *quite* enough zoom even on a crop frame to get a good picture of Saturn or Jupiter, but it does great for the moon and stationary terrestrial objects! I compared the results to the S23's zoom and it is night and day. If I wanted to spend a bit more time and effort, I could probably get nearly crystal clear images of the lunar surface, but even without seriously fiddling with the focus, it gives a significantly better image than the S23 and its witchcraft of cropping a 200mp image and using AI and extant images to fudge the results. It is a beast though. I'm 6' tall and even collapsed with the 2x adapter, it's longer than my forearm. That said, it's not heavy! A sub-$100 tripod will easily hold it up even with the attachment being on the camera body. Again, I have to make sure people understand: there is no autofocus, you zoom by literally pulling the lenses apart from each other, there is no image stabilization, and it absolutely needs the telescope mount. What do you expect for a $150 lens? That said, this thing is an amazing value. Go check for a 500mm lens right now. It's probably more expensive than this thing. Sure, your uses are going to be more limited especially as you learn to finesse the focus, but for the price, I don't think you're ever going to do better. Obviously these aren't Zeiss lenses, and you're going to have to live with correcting some chromatic aberration. That's to be expected. Even in my best lens, there's a tiny hint of it. If you're looking for a recommendation to get this lens, you've got one here. Just understand the limitations and you're good to go!

Good learning experience so far
I am new to astrophotography, and to photography in general. I bought this lens because I wanted something affordable to capture some decent photos of the moon, and to learn more about my camera and photography. I am finding this manual focus lens is great for learning. I feel like a lot of the negative reviews are due to lack of experience and patience. It is a manual focus only lens; there is no electronic communication with the camera. The aperture setting (a term I was unfamiliar with 2 weeks ago) is constant, relative to the focal length of the lens, and also cannot be otherwise adjusted. There is no stabilization control. You can (and probably should) adjust your cameraโs shutter speed to minimize blurring due to instability. Iโd like to try and get some shots of the planets with this lens and see how that goes. I recommend a sturdy tripod, a remote shutter, and a willingness to be patient and take your time learning. Here is my best shot so far of our beautiful moon! :)

Good Lens for the Price
Fits my Canon Rebel T5 perfectly. It is easy for me to use and offers great zoom functions. It isn't automatic focus so it takes a little bit of practice to focus the lens on a small subject. Looks professional and a pretty good lens for the price.

DO NOT BUY
Horrible quality. It broke in half on my first use. I was able to put it back together but the shot picture is all screwed up now. Do not buy this. Spend the extra money and get a quality lens!

Great zoom!
Love it! I use it with my Canon T100, and got a beautiful picture of the moon! Highly recommend if you want a good lens without spending a fortune.

A Little Better than Expected
Bargain bin shopping can be an adventure and a bit like playing the lottery. Sometimes you miss, sometimes you do alright, and sometimes you get a hit. This is alright. It's not a hit; at the same time it's not a miss, either. It has the capability to take clear, sharp photos and does well. Everything is manual; there is no auto-focus or image stabilization. I use a tripod and wireless remote shutter to take photos with this. It's not a bad product and does alright for a hobbyist who can't afford a branded telephoto lens that costs hundreds or even thousands.

Works with Canon Rebel T7
Update the more I learn how to use this the more I'm in love with it. If you're thinking of getting it think no more. Must have patience. So I never do reviews, but I really wanted to clear things up, there are reviews stating this doesn't work with the rebel T7 WELL IT DOES WORK. I purchased this to give it a whir. I didn't want to spend a fortune. So I purchased this. Remember this is all manual no auto. It takes time to figure out the proper focus, but I just focused on another city's water tower from our house and the distance is 9.6 miles away so yes it works. So those of you that say it dosen't work, give it some time and don't give up and try. I purchased this mainly for our trips out west to spot out wildlife. I can't wait to take it and try it out.

A good economy lens
I read the reviews and was concerned that this lens was completely manual but I ordered it anyway. After some practice I think I have it. So far Iโm very happy with the results. This is not point and shoot, you have to get accustomed to manually focusing in quickly, use a tripod or stick to assist in steadying, and use a light touch. Sounds like a lot but it isnโt, just takes some practice. I will have to use a remote shutter release if I use the doubler however, keeping in mind the higher the zoom the more any movement of the camera affects the focus. Iโm happy with this lens, much cheaper than spending thousands of dollars and gets the job done.
