About Bower SX7DGN

The Bower's 2x DGII Teleconverter (7 Element) for Nikon will effectively double the focal length of your Nikon lens, while maintaining the autofocus function - a 35 mm lens becomes a 70 mm lens. This 7-element teleconverter uses multi-coated optics to deliver improved image quality. With an 85 mm f/1.4 lens, for example, the focal length will become 170 mm, which effectively sets the maximum aperture at f/2.8 (cutting the amount of light captured by two f/stops). This teleconverter is a portable, high-quality and versatile accessory that's well worth having in your camera bag. It's only compatible with lenses with a maximum aperture greater than f/4.0 in order to fully utilize its autofocus capabilities.

Questions about this item:

Gary M  will this teleconverter work with Nikon D5000?
JOHN L  The converter will fit the camera if it has a Nikon mount, it's the lens you need to check to see if it will fit.
Shopper  Will this teleconverter function in all aspects with a nikon D 7100 including but not limited to autofocus?
Andrew R  Unfortunately no, I don't believe so. To the best of my knowledge, the D7100 it will operate in a manual configuration when this teleconverter is used.
fred h  will this work with the nikon d5000 camera? I want to bring my telephoto 300 up to 600. will that work?
ROBERT C  theoretically it will work because the max aperture will be f5.6 but you never know about third party converters. I have an older tamron that will not work but a newer Sigma that works fine.
