The Vivitar Macro Focusing Teleconverter is a precision optical component designed to expand your photographic capabilities in two ways: As a premium quality 2X teleconverter, it effectively doubles the focal length of the lens it's used with and maintains the resolution and contrast of any fine optic at a higher level than most standard teleconverters. In addition, the Vivitar Macro Focusing Teleconverter's unique focusing mechanism enables you to do macro work without modifying or adding other equipment to your lens/teleconverter combination. With the Macro
Focusing Teleconverter your standard 50mm lens becomes a 100mm macro lens with a reproduction ratio of upto 1:1 (lite sze image of your subject on the film piane).

The Vivitar Macro Focusing Teleconverter is designed to work with a variety of high quality lenses: 50mm and other fixed focal length lenses from 28mm to 400mm, plus zoom lenses including Wide to tele and telephoto zooms. The 2X (doubling) function is the same with any compatible lens; the macro function varies depending upon the particular lens. For example, standard 50mm lenses have similar optical design and mechanical construction, so when used with the Macro Focusing Teleconverter the results will be almost identical, even for 50mm lenses from different manufacturers. Other lenses, however, particularly zoom lenses, have great variety in both optical design and mechanical construction; results for lenses of identical focal length from different manufacturers may vary. For instance, lenses with dose or macro focusing will yield different maximum magnifications when used with the Macro Focusing Teleconverter than lenses of identical focal length without a close/macro focusing mechanism.

The chart as shown illustrates results when using the Vivitar Macro Focusing Teleconverter with several specfic lenses; your equipment may or may not provide very similar results.
Experiment... exploring combinations available with your own equipment will give you working familiarity with your new Macro Focusing Teleconverter and some terrific shots as well.




To insure proper meter coupling with your camera, first mount your Vivitar Macro Focusing Teleconverter to your camera as you would any of your lenses. Seat it securely; do not overtighten. Attach your lens to the Teleconverter in the same manner as you would attach it to your camera. Properly mounted, the Macro Focusing Teleconverter coupling system fully maintains automatic meter and diaphragm operation. Note to Nikon users: The Vivitar Macro Focusing Teleconverter is compatible with Al series Nikon cameras.
Ths includes the F3, F, FM and EM. It is not intended for use with the old F series cameras (F2, Nikkormat EL, ELW, FT2, FTN).


The Vivitar Macro Focusing Teleconverter doubles the focal length of your lens while reducing the amount of light striking the film by 2 stops. Cameras with auto exposure control will adjust to compensate for this light difference; shutter priority cameras will open the diaphragm 2 stops while aperture priority cameras will slow the shutter speed to 1 /4 of the value with the lens alone, i.e. 1 /500 sec. without the Macro Focusing Teleconverter becomes 1 /125 sec. with the Macro Focusing Teleconverter.

Most SLR cameras have through-the-lens metering; the camera meter reads the exact amount of light being transmitted. However, non-coupled or external (hand-held) meters will requireexposure compensation for the 2 stop light loss. Either the aperture, the shutter speed or a combination of both can be adjusted; since wider apertures result in reduced depth of field, your adjustment method should consider your depth of field requirements.
The Vivitar Macro Focusing Teleconverter has two engraved focusing scales. Both of these scales are intended for reference when the MFTC is used with a standard, 50mm lens.The numbers on both scales indicate magnifications (not
distances). The blue scale is used when the prime lens is set to its closest focus position. On many 50mm lenses this is at a distance of 0.45 m; however, if your 50mm lens closest focus distance is slightly different, say 0.6 m, the reference figures are still valid. The white scale shows magnifications when your prime lens is set at oo. You may use either scale for reference; if you wish to shoot a subject at a specific magnification, i.e 1:4 or 1:5 etc, the white scale (prime lens set at oo) may be more convenient.
