The model DCR-2025PRO high definition telephoto lens is made of high index optical glass elements, and it's designed with new designing concept of two-group/four-element formula to obtain the maximum resolution power of 260 lines/mm resolution power at center (MTF30%), while it has low dispersion. There will be no reduction of light value (F.Number) when this conversion lens is attached on the camera's lens. By using a suitable adapter and/or holder, the DCR-2025PRO lens can be used with the appropriate digital still camera or digital camcorder, effectively. DCR-2025PRO comes with 4-adapter rings for 43mm/ 52mm/ 55mm/ 58mm filter sizes and a LS-082 lens shade. The lens shade will cut an unwanted light beam, and it reduces flare and ghost image effect considerably.

Well built accessory to expand the reach of your lens.The larger front opening means that you are not sacrificing any f-stops, as you would with a teleconverter. This is not meant to work as a standalone lens. This goes on the front of another lens, which is attached to your DSLR camera or video camera.The back opening is threaded for 62mm. If that matches the front threading of your lens, you can attach the Raynox directly to your lens. However, if the front of your lens is smaller, the manufacturer includes four adapter disks to step down to other sizes. As an example, I bought this to use with my 70-300 zoom lens on my Canon 6D. The front of the 70-300 lens is 58mm, so I used the 58m adapter. Screw the adapter onto the Raynox and then screw the combination onto your lens. Check to make sure you can unscrew everything! The threads are plastic and can easily be damaged.Another benefit of being attached to the front of the lens system is that the Raynox does not interfere with the autofocus or image stabilization functions your lens may have. The Raynox also comes with a great hood, caps for covering the ends when not in use, and the most protective storage pouch I've ever seen. Seriously, I'm going to use this on something much more expensive than the Raynox!Of course, putting a moderately heavy lens on the front of your existing lens and then zooming the combination out to the max makes for a long and front-heavy combination. But this is true of any long zoom lens. The Raynox has a wide and deeply knurled section that helps you hold everything. Also, holding the Raynox is safer than holding the lens attached to the camera just in case things come loose.If your zoom has image stabilisation, you might be able to use this hand-held but more likely you are going to need a tripod to use this effectively. Again, this is true of any really long lens.My only gripes are the plastic threads on the adapters, and the back cover. I would rather leave the 58mm adapter mounted permanently, but the back cover won't fit in that case. A minor point.Edited to add-------------------So, how do the photos look? They look great! The only issue is vignetting. This may be a more serious issue for me because I am using one of the adapters that step down from 62 to 58 mm. Focusing on distant subjects (as you are most likely to use this) yields either no vignetting or only a very slight darkening of the corners. Focusing on a subject that is near the minimum focus distance causes severe vignetting - like looking through a port hole. In normal use when trying to capture distant objects, I don't think you should be worried about it.
