I think you mis-read my post.So in the analog only section, no discussion of digital light meters is allowed? That pretty much limits it to the little Sekonics and a Gossen, and out-of-production hand-held meters. Even film cameras have digital meters now, and have for a while.
Thank you, I'll call both places and decide how to procced.I called Samy's on Fairfax and they said for most older light meters they recommend Spectra City Meter Repair. Others they send to the manufacturers, but be sure to contact the repair place or Samy's first.

Hi Wilt,You live in SF Bay Area...meet me somewhere and I can test your meter against 2 handheld and one in-camera meter, against an 18% grey target, and tell you if it devaates at all from meters which all give me dead on accurate exposure!
Hi Wilt,
The two meters are definitely off. I have a Luna Pro F and a Minolta Auto Meter III that are very accurate, as well a a new Sekonic meter that I just bought. These three meters all agree with each other, but my two Minolta Auto Meter IV-F models are different story. On one of them, I have to set the ASA two stops lower to agree with my good meters and the other requires that I set the ASA three stops lower. As you might imagine, I'm not exactly thrilled about this.
You might try cleaing the meter' contacts in the measuring head. There should be a video on youtube, using a crisp dollar bill (the raised engraving ink acts as a mild abrasive) to clean the contacts. Worked for me.Hi Wilt,

This link wrongly calls it 'calibrating', but it really is cleaning the contact so that oxidation no longer prevents the contacts from connecting!You might try cleaing the meter' contacts in the measuring head.

NOW WE’RE TALKIN’wiltw and Zathras, stop by here in Pacifica and I'll fire up my Kollmorgen light standard and you can check all them against a standard.
Wow, a local boy! Gotta keep in mind the availabiliity of a test standard.wiltw and Zathras, stop by here in Pacifica and I'll fire up my Kollmorgen light standard and you can check all them against a standard.
Yes you can it's just that Brad needs smelling salts if you do.So in the analog only section, no discussion of digital light meters is allowed?

Is the Pentax Digital Spotmeter a digital meter, or an analog meter with a digital display? If analog, is the digital display the offending characteristic?
Are the meters in film cameras which have LEDs and LCDs in the viewfinder analog or digital? If digital, can we discuss their metering characteristics in the analog section? The reason I ask is that I was sort of checking around and found this about the Nikon F4 metering system, which uses LCDs:
"As Matrix Metering demands a great deal of raw computing power to process complicating data analysis and at the time of its introduction, Nikon F4 can easily claim to have installed one of the most powerful on board computer processing circuitry in applied camera design. As a powerful system is required to instantly process various data pertaining to exposure metering, focus detection and mechanical parts control with stepless lens-body interface via super-fast computation - all aim to achieve one single photographic objective - outstandingly accurate exposure results."
I don't know, maybe they are talking about an analog computer or something. With a digital display.
As you may have gathered, I am perplexed by the moderator's most recent ruling on forum decorum. I don't want any self-described analog photographers to turn to stone or anything, but is this pronouncement a bridge too far?
The Pentax Digital Spot Meter is a digital meter. There is a Pentax Spot Meter is an analog meter with an analog dial IIRC.
Even a 'digital' camera sensor is an ANALOG device, each pixel whose signal is processed and goes thru and ANALOG-to-DIGITAL conversion.
Similarly, the light meter starts off with an analog signal generated via its photosensor, and that signal is amplified and interpreted to either drive a swinging needle or converted to drive a digital DISPLAY..
As I posted IIRC, but in all fairness I have not disassembled my spot meter.
Every photosensor is a photoresistive device, or a photovoltaic device, and both have continuously variable values that result based upon the intensity of the light striking the photosensor. Continuously variablle, or analog.

So it belongs in the hybrid discussion area.
Got it.
Personally, I operate all of my cameras with my fingers. As they are digits, this means my cameras are all digitally operated, right?
Why is it different? Doesn't each pixel sensor output an analog signal?Every photosensor is a photoresistive device, or a photovoltaic device, and both have continuously variable values that result based upon the intensity of the light striking the photosensor. Continuously variablle, or analog
Of course, mirrorless camera metering is a different story.
I would argue that film is more digital than digital.
Take monochrome: Digital presents 8 bits (jpeg) or 256 grey values per smallest unit of imase (pixel): 1-256
Negative is either black or clear (1 or 0): digital
