Exposure meters

Minox exposure meters.

Other small pocket exposure meter

MinoSix meter was designed in 1951 for Minox A camera. It had a selenium meter made by Gossen.<P>

MinoSix dimension 5.3 x 3 x 1.8 cm. It has a viewfinder (with or without frame ) It comes with a chain and a case.<P>

To use MinoSix, set the ASA/DIN number with the thumb switch at the back. View object through viewfinder as if through Minox A, press the button on top of meter to measure light, release the button to lock reading.

Then read off the shutter speed from the meter.<P>

Since Minox A camera's COMPLAN lens is always set at f3.5, there is not need to change aperture. <P> However,Minox meter can be used on other cameras with variable apertures. Through a coversion table at the back of MinoSix, the meter can be use for aperture from F2 to F8; addition table in the instruction allows it to be used from F1.4 to F32

After 1954, Minox changed the engraving on the exposure meter from MinoSix to miNox mouse logo.

The functions are essentialy the same.

Some Minox meter has only ASA numbers, some with ASA and DIN.

MinoxSix and Minox meters are collector items.

I use rather a Sekonic Auto Leader model L 188 battery operated exposure meter.

It is quite light, and more sensitive, allows ASA from 6 to 128,000

instead of only ASA 25 to 200. One downside of Sekonic L 188: it has no expousre lock,

it moment you release the button, the meter needle springs back to zero.

When I am using Minox IIIs with a 35mm camera with meter, such as Minox GTE, Rollei 35 etc,

I just use the 35mm camera meter.

The selenium exposure meter of Minox B is a Gossen

There are two version, the first version of early Minox B has a windwon screen type grid;

second version of Minox B has a honeycomb grid selenium meter.

Minox B exposure meter is coupled to the build in ND filter ( operate by the milled filter rod in viewfinder window )

such that when you pull out the ND filter to cover the lens, the exposure meter needle will point to

a lower reading.

Minox B has a built in ND filter and a green filter. However, the green filter

is not automatically compenstated. When you use the green filter in Minox B, do not use the triangular pointer /\ on the meter, instead use the little dot '.' at its left hand side to align it with the meter needle (by turning the speed dial ).

A question related to the miNox meter: what is shutter speed range

shown on meter? Are parts available for these meters?

miNox meter shutter ranges:<UL><LI>

ASA 25: 2,1,1/2 1/5 1/10 1/20 1/50 1/100 1/200 1/500<LI>

ASA 50: 1 1/2 1/5 1/10 1/20 1/50 1/100 1/200 1/500 1/1000

<LI>ASA 100: 1/2..... 1/2000<LI>

ASA 200: 1/5......1/4000</ul>

For other ASA NUMBERS multiply or divide accordingly

For lens other then F3.5, use table at back of meter( f2,f2,8, f4 f5.6,f8)

When using MinoSix/Minox meter or the built in meter on Minox B, you must

point the camera or meter at the object, be careful that the meter window is not accidentally blocked by a finger, then you must press the meter read button of the meter. Otherwise the meter will not move.

When you switch in an ND filter of Minox B, you must also press the READ button to see the difference in meter readings

EI range of Sekonic L188 meter: 6 to 12,500.

This suits Minox 8x11 camera just fine. At one end, EI 6 covers the

high resolution microfilm Fuji Super HR, at the other end, 12,500 covers high speed film Kodak TMAX P3200 pushed to 12,500 with Tmax developer.

Something I am curious about is how does the meter come apart..mine

has a broken glass,so I found a peice of slide glass that fits, but

I Suspect that to fully dismantle the meter one must FIRST remove the

chart decal from the back of the unit, risking damaging the decal.I

even called minox in GERMANY,and they said the no longer carried any

technical or servicing information for these meters...oh well

David -

<p>

The meter I just purchased has a loose back plate. The "label" on

mine is actually a rather thick (.005?) metal plate secured with the

brass screw and also glue. You should be safe to remove the screw and

slip an X-acto blade under the plate - the glue on mine is quite

brittle. Good luck!

Martin, are you aware that there are several different versions of

the later (non-Minosix) meter? These are differentiated by the marked

ASA range on the scale. The three that I know about are:

<p>

ASA 10,20,40,80 <a

Picture </a>

<p>

ASA 12,25,50,100 (As shown in Moses' Spycamera book)

ASA 25,50,100,200

My meter (S/N 84 1xx) has the 25/50/100/200 scale. It must be a later

one...

I some times use a Leudi extinction meter for my Minox IIIs

<p> Leudi meter was made in Austria. It is still the smallest and

lightest exposure meter, weight only half oz, including the box.

Look through the Leudi window, there are numbers from 1 to 8,

point the Leudi to the object, indentify the dimest number you can

still see, then turn the Leudi celloloid belt to align the number with

the environment, (sunny, hazy, indoor, etc ) and read off the shutter

vs aperture.

<p>I have a seemingly simple question. Like James and others have noted - minox made several models of light meter with different ASA guides. I have come across the 12, 25, 50, 100asa meter. Then I saw one on eBay with 25, 50, 100, 200asa. My original meter is working well but has 10, 20, 40, 80asa settings.<br>

My problem is that I shoot with 25asa (minopan), 50asa (Konicolor, Fujichrome) and 100asa (Various) so what setting should I put my light meter on since it does not have ANY of these asa settings? Is there a way to calibrate for the film I am using?<br>

Thanks, Dean</p>

Leudi extinction meter</p>

In the 60s-70s, it was custom to use ASA 20,40,80 instead of ASA 25,50,100. Use the closest current ASA number, for example

of the meter indicate ASA 40, then use ASA 50 instead etc.

MinoxSix meter is not sensitive enough

Now I use Vogtlander VC II exposure meter
