Thanks to all who previously wrote reviews listing information about this lens converter for Canon EOS digital. I really needed and wanted a 2x converter for my Canon Rebel XT to use with my 75-300 telephoto lens. I got conflicting information prior to coming to Amazon site. Previous comments really helped!! I am very satisfied with this product. Like it stated you have change two f-stops - but hey - using the camera on manual is the only way to go. The converter is auto-focus so no problem. Great photos!! Bower is a local company in the USA with products made in Japan, what else is new.!! Thanks!!

The Bower Digital Macro Filter Kit includes three close-up diopters of +1, +2 and +4 magnification, a durable leatherette carrying case, a lens cap, and a "cap keeper" strap. These filters simply screw onto the front of any 77mm filter-size lens to magnify the image size while maintaining resolution and picture clarity, effectively transforming your lens into an amazing macro lens. As an added benefit, you get this increase in magnification without any exposure loss for truly no-fuss close-up photography. Plus, these filters are male/female threaded, which means you can combine them to achieve even greater magnification (all the way up to a total of +7 if you wish) -- or you can attach additional standard filters such as polarizers and UV filters, or even special effect and colored filters for even more interesting and creative photographs. >>> These macro close-up filters are ideal for photographing small items and focusing in on details of coins, stamps, flowers, insects, and jewelry -- as well as industrial photos of miniaturized components, medical and dental laboratory work and other scientific photography.
For the price, you can't beat this combination of add-on optics to get as close to a subject as you would want to (unless you have a microscope handy). Although used infrequently, when you see something that deserves a really close inspection through your camera's lens, this will do the job without distortion. However, unless you have a really steady hand or fast lens, I would suggest using a tripod for optimum results.

Product Features
Description
The Bower MC4 2x teleconverter (also known as a tele-extender) will multiply the focal length of the existing lens by 2x, and will cut back the amount of light by 2 f/stops. This precision optical accessory, which is compatible with your Nikon SLR camera, allows you to increase the focal length of your lens without sacrificing optical quality. For example, using a 2x teleconverter with a 300mm lens will effectively increase the focal length to 600mm. A lens set to f/2.8 will now be f/5.6. It also reduce depth of field to the 50% of the master lens.

I just got (after 8 working days, that is fast!!!, all the way from Seller at NYC to Mexico City, for only 10 bucks!!!) the Digital Concepts (Sakar) 2X Teleconverter for Sony Alpha. It is very well constructed and fits perfectly, in fact it is just the same construction and quality as some other brand-name teleconverters (Vivitar, Bower, Kenko, I guess they are all manufactured at the same plant... -China-). As expected, it doubles focal length at the expense of lens speed by also 2X, that is if you use a 75-300 4.5-5-6f (as I do), you will end with a 150-600 11f. Performance is pretty good considerng that you will loss autofocus with such small aperture but anyway no need to autodocus on distant objects as infinite position is almost a constant at such far away targets. I have taken some amazing moon shots and far away volcanos with great success. I still beleive that this is a much better solution against croping on your camera or PC. All in all, I fully recomend this teleconveretr to expand your lens collection, and for the price you will end doubling your reach and lens stock!!!!
