It has an focus ring and it works. Attached to my Samsung Galaxy S4 it makes the nice quality photos in good light conditions. I have not tried it in low light conditions yet but I do not expect very much since there are limitations phone also in low light. Attachment of the telescope to the Galaxy S4 cover part looked very flimsy but for my surprise it was actually very solid. Focus ring of the telescope works very poorly. At first I thought it was totally broken because it was totally stuck in one position. When I turned focus ring back and forth very gently it started moving bit by bit and I managed to move it to the longest focus. Now I do not dare to move it or it takes very long time to move back. Tripod can be only used with telescope and the way it is attached to the scope with bigger ring is odd and flimsy. When you attach the ring you have to tighten with a small screw to scope and then you have to screw the tripod to the ring. I also ordered additional stand for mobile phones or small cameras. http://dx.com/p/360-degree-rotation-folding-stand-tripod-w-bracket-frame-for-cell-phones-black-198978. I found it better stand than the one that came with the package. This is because you can use it with or without 12x telescope lens. So actually the tripod which came with the package is useless for me. Good 12x telescope lens for the price. Not superb but good. Tripod and attachment ring to scope is flimsy. Read more
