Equipment Type: Others
Equipment Brand: Light / Flash Meter
Equipment Model: Sekonic L-328 and an Unused Minolta Booster II
Price (S$): $150 & $150
Description:
On sale here today is a Sekonic L-328($150) with user marks on the exterior casing. What you see in the pictures are what you get, no box or anything else. Just the meter with the lumisphere attached.
The Minolta Booster II($140) 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.
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.
Condition is like brand new or unused. Comes with a copy of the manual.
How do you calibrate Minolta Booster II on ground glass?
1. Aim the camera with the lens focused at infinity at an evenly illuminated surface. The surface need not (and ideally should not) be in focus.
2. Take a direct reflected reading of the surface (not through the camera) by removing the groundglass attachment from the booster, extending the shield at the end of the probe, and reading with the booster set at its minimum setting. Note the reading. You can take reflective readings in general in this way.
3. Now replace the groundglass attachment and take a reading in the center of the glass with the lens wide open and the glass well shielded from stray light with a darkcloth. Adjust the dial on the booster and recheck until you get the same reading as the direct reflective reading. If you cannot equalize the readings (usually because the lens does not have a sufficiently large maximum aperture), then set the booster to the maximum and note the difference from the reflective reading, and just add the difference as a correction factor to your exposures.
