Product Description

Style: Nikon

The 2x DGII Teleconverter (4 element) for Nikon uses upgraded multi-coated optics to double the focal length of the existing lens. Using the 2x DGII teleconverter with an 85mm f/1.4 lens, for example, will double the focal length to 170mm, which effectively sets the maximum aperture at f/2.8 (cutting the amount of light captured). Also known as a tele-extender, it serves as an excellent lens modifier that is portable, high-quality and versatile. The lens used must have a maximum aperture greater than f/4.0 in order to fully utilize its autofocus capabilities.

I use it with my 75-300mm Sony lens with a Sony alpha to E-mount converter on a Nex-6 camera, and it works... but with full zoom the pic wasn't clear as without it.

note: my lens doesn't have auto focus only manual

I am a starting to take bird pics and this works pretty good with my kit. The auto focus is a little shaky but that could be me

The Bower SX4DGN will be a life saver for many. If you need a fast 100mm portrait lens, slap one on your DSLR and boom! Your 50mm f1.4 or 1.8 becomes a flattering f2.8 or 3.6, 100mm .. Why portrait and not general purpose? Kindly put the Bower tends to reduce contrast and soften the images "only perhaps" a bit too much for serious photography. Portraits on the other hand often need to be a little gauzy in order to be kind to the subject. How many times have you seen a pro put a softar or some other kind of softening filter in front of hundreds or even thousands of dollars worth of glass? MM hmm, this Bower is a fraction of the price of a good softening filter. Please don't construe this as it turning the image to mush. This is absolutely not the case. It maintains autofocus on most of my Nikkors and attaches to my D7100, D800 and D600 with a very reassuringly solid click. If you don't need huge enlargements this Bower will surprise you with it's build quality and faithful color rendition. A winner. Solidly recommended at the price.

A lot less expensive than a 600 mm zoom lens. Does cost some sharpness though, it seems.
