Analogue light meters

[foo]

Hi, all just wanted to know if analogue light meters are as accurate as digital .Having just purchased a Sekonic l 158 lumi meter , was wondering how accurate these old meters are. It measures reflective light only I think no battery needed . I did a couple of test shots with the Sigma 28mm mini wide and they don't seem too bad. Is there any meters ( cheap) that I should be on the lookout for please .

It is not really a "analog" vs "digital", here, but rather a question of material which the sensor is made of. The old, very old light meters are built around selenium, whereas newer use silicon or arsenic-phosphorus cell (sensor).
Selenium light meter does not require any power supply to run (light itself sets it into action).The problem with the selenium is that it evaporates with the time, thus becoming inaccurate (after a few years of usage). The other materials are more durable, but such meters require battery to run.

Sekonic is a trustworthy brand, and I guess you can rely upon 158's calculations. Just remember that ASA=ISO (basically), and that's it...

"be on the lookout for" any newer model(s) of Profisix/ Lunasix, for "general" usage http://goo.gl/oC57WO or some spot-light metering units, but these are going to cost you lot:

Thank DraganDL , its seems in good nick and was only beer money , I sold the jessop one I has as it was way out .
Very small scale for ASA or ISO tho .
But I'm happy with it.

No problem with the scale's scope - you just double any of the two NOMINAL values (either that of aperture or of a shutter speed, upwards) with every ASA/ISO value being doubled. For example: you don't have a 3200 ASA/ISO, because the scale goes up to 1600, but you want to shoot at ISO 3200. No problem - you've had a set of f/8 plus 1/250 sec for 1600ISO, so just "raise" the shutter speed (which really should be called "exposure time") to the value of 1/500 sec or leave it at 1/250 sec but raise the value of aperture to f/11. Instead of 1/250 sec plus f/8 at 1600ISO, you will set the camera parameters to 1/500 sec plus f/8 at 3200ISO. Or 1/250 plus f/11, or 1/1000 plus f/5.6...

edit: "Very small scale for ASA or ISO tho". Did you mean it's physical size (dimensions)? If so, there isn't a cure for that (or get yourself a magnifying glass)

Yes I meant physical sizecand did get a magnifying glass as well .
Also bought now the Sekonic l 3o8 s flash meter as present from my wife , its winging its way from hk as I type .
