JINTU 2X Converter Lens Teleconverter for SLR & Digital Lenses with T Mount Lens

This does exactly what it says it does.

The manual focus is the only real downside at this price point. When zoomed in this far, manual focus is incredibly difficult unless your tripod is super stable. But for the price, you can see some cool things you otherwise wouldn't seemwithout a super expensive lense. I took some shots of the moon and it looked decent on some parts. Some color aberration around the outer edges, not sure if that was the lens or atmospheric/heat effect. This is not a high quality lens, so don't get your hopes up, but if you just want to experiment with shooting the moon or other distant things, this is a great starter kit of sorts.

It works great with my cannon t3.

Not really 2X magnification and not the sharpest image but for the price, its a good deal. Focusing takes some practice.

Clear lens, works as expected, great price

When I first received this lens, I fell in love with it. It worked great for my Canon Rebel EOS t7, but after about two weeks of use, the lock ring would not lock the lens in place. Several times the lens would extend all the way out when taking pictures or slide back so hard that I was certain it broke my camera. I contacted the seller and they sent me a new lens. I was thrilled but however also after using it two weeks it fell apart just like the other one. The seller had sent me videos to show how to use it and it was exactly how we used it. I first gave this lens a 5 star review but after use, I have to give it one, I had to trash both lens!!!

This was a great investment to go with my Juno telephoto lens. The first picture is with the 2x converter at 840mm. The second was at 1600mm with the 2x converter.

This is an addition to another adapter. I used them both together and attached them to the scope. I get a longer distance and moon pictures are very detailed. Good price and quality.
