WTB: Replacement diffuser for minolta IV flash meter

padu · December 24, 2006

Hi,

I just got a used minolta IV flash meter from ebay. It came with a flat diffuser for illuminance (lux) calculations. I want the regular spherical diffuser (not the 4x or 8x accessory one). Do you know where to get one? Or if you have a spare one that I could buy...

Cheers

Padu

(PS: I'm willing to trade the flat diffuser if you need it)

bump...

I still need it... It's been almost two weeks I'm looking for it and nobody seems to have it in stock.

If I don't find it, I'll probably sell my meter and buy a more modern one... bummer

The closest I found is an 8x ND dome (not sure if it will even fit):

I found some 4x and 8x, but I'm not sure if they'd be usefull. I'll be doing most of my shoots using an AB800 indoors.

Well, one thing that I found interesting is that if I use the meter with the flat diffuser as I'd normally do with the dome, the picture is underexposed. If I remove the diffuser and measure incident light with the sensor facing the camera (no diffuser), the picture is slightly overexposed, just the way I like it for digital.

That's how I've been using it lately, but I don't know what are the collateral effects of using it like this.

A diffuser is still an advantage when taking an incident reading, so I suggest using the diffuser and compensating with the ISO setting. (The diffuser reduces the directionality of the meter.)

Use your digital camera in manual mode to measure an 18% gray card in the middle of the histogram, record your exposure settings, then adjust the meter in incident position using the ISO dial until the exposure on the meter matches the camera. Now you just remember the ISO difference between the camera and the meter, and you have a meter calibrated to "your" camera.
