Pentax Spot meters

[Robert Ruderman]

Hi,

Other than a display and physical size difference, are there any functional diff erences between the analog and digital versions of the Pentax spot meters? Why would one choose the analog version over the digital version (discounting the pr ice factor).

Thanks, Robert

I have had a Pentax digital spot meter for 9 years. It's been dropped more time s than I care to remember. "Takes a lickin' an' keeps on tickin'" or whatever.

The analog meter uses a galvenometer. It is more susceptable to drift over time and is also somewhat more delicate. If you use your equipment out of doors, I' d go with a digital meter.

You might also consider the new Sekonic 508(?). It incorporates both a spot and an incident meter in a weather-resistant body.

Good luck!

A friend of mine has the analog and I have the digital meter. They were both mod ified by Zone VI a few years back and still are within 1/3 of a stop of each oth er in all lighting conditions. The main appeal of the digital over the analog, f or me, is the way it works in low light situations. The digital diplay is much e asier to read in low light, with out having to push an extra button to turn on a light in the display, as some meters have. It is also less prone to reading err ors, you know that a 14 is a 14, and don't have to track a needle along the numb er scale. Otherwise, they both have performed admirably over the years, and eith er is a good choice for the long haul.

I use the analog spot meter. I prefer it to the digital meter. Why? Have you ever noticed that aircraft, nuclear power plants, and other mechanical devices t hat require careful operator monitoring use analog displays rather than digital? It is partially because it is easier to scan and mentally process something vi sual than look at a digital number and process the meaning in your head. For ex ample, it might make a BIG difference if a temperature gauge in a nuclear power plant read 1800 degrees rather than 1200 degrees. A readout that says "1800" ra ther than "1200" may not catch someones attention as much as a gauge that has a green zone and a red zone.

What does this have to do with spot meters?

When I read a scene for the highlight and shadow areas, I think about the latitu de of the film I am using and watch the needle swing as I look at different area s. I get a more "visual" impression of how many stops of light I see and can pl ace the exposure with ease by eyeballing the central reading on the meter after watching where the needle swings. This technique more closely corresponds to ho w I think about stops of light than a numeric display.

Digital may be more shock proof, less prone to wander, etc. etc. It does not co rrespond to how I think about light.

I know this is a little off the subject of this post, but I was wondering what to do about the battery in my Pentax Spotmeter. It is an older analog style (there is a picture of it in the Ansel Adams book). I can't seem to find a replacement battery. Wein makes something that is too small to fit. Radio Shack has a battery that is about .15 volts too hot, it fits... but doesn't work. Anyone with a idea for this?
