I love meters, too. My collection:
Minolta Flash Meter II: Made in 1975, the year I was born. Still spot-on accurate.
Minolta Auto Meter IIIf: The first handheld meter I ever bought. I saved money mowing yards when I was 15 to buy it. It cost me $206 new.
Sekonic L-758DR: I like this meter so much that I bought two of them, both brand new. I only use one, the other is kept as a backup in case the first dies or gets lost. I use this for pretty much all of my work. It does incident metering and one degree spot metering.
Pentax Digital Spotmeter (Zone VI Modified)
Pentax Digital Spotmeter
Gossen Ultra Spot II: The first spotmeter I ever owned. I bought it when I was in college. Its the worst spotmeter I've ever used. It is huge and heavy, but worst of all the sensor is EXTREMELY sensitive to infrared and is overly sensitive to red and orange visible light, too. This is a problem I have found with Gossen meters generally.
Gossen Ultra Pro: Incredible low-light performance, does incident and wide-area reflected metering. Great for the
Incident/Reflected Averaging method for determining exposure for backlit subjects. Unfortunately, it has the typical Gossen oversensitivity to IR and warm light. It underexposes one stop under incandescent and halogen lights and in very warm sunlight, like at sunset or sunrise. Matches my Minolta, Pentax, and Sekonic meters in normal daylight, LED, and fluorescent lights.
Weston Master V: This one was rebuilt by Ian Partridge in the UK. The Invercone incident light attachment for this gives more accurate readings in extreme side-lighting than the normal dome-shaped incident receptors all other meters use. I've always wondered why no one else has made one like this.
I did a
comprehensive series of tests of the spotmeters I own, checking their color sensitivity, IR sensitivity, and flare control that you might find interesting.
