The Minolta Booster II Set consists of a Booster II, Spot-Probe Attachment, Microscope Attachment, 35mm Film-Plane Attachment and SLR Eyepiece Attachment. The Booster II is a high-sensitivity receptor which fits the Auto Meter IVF and Flash Meter V. Among its many applications, professional photographers will find the Booster II useful for metering subject brightness off a view camera's focusing screen when the Spot-Probe Attachment is attached to it.
- SLR Eyepiece Attachment: The SLR Eyepiece Attachment enables taking centered, circular TTL exposure readings through the camera's lens. This function is important if you own an SLR camera that does not have a built-in meter. It is also useful for taking TTL flash measurements.
- Spot-Probe Attachment: Measurements off the focusing screen of a large format view camera are possible when the Spot-Probe receptor is attached to the Booster II. This method of metering is very useful for close-ups and macrophotographs since the metered exposure already includes any exposure compensation required for bellows extension factors.
- 35mm Film-Plane Attachment: Highly accurate measurements of flash or ambient light at the camera's film plane are possible with the 35mm Film-Plane Attachment. This method is more accurate than measurements taken through the SLR eyepiece because the Booster II measures the light that actually passes through the camera lens and strikes the film.
- Microscope Attachment: By using the microscope receptor, direct readings through the microscope's optics are possible. Flash exposures can be calculated when using the Flash Meter V and Auto Meter IVF.
The Booster II requires one 6.2v, four LR44 or equivalent battery. Dimensions: 37 x 113 x 25mm (1 7/16 x 4 7/16 x 1"); Weight: 95g (3 3/8oz.)
