When activated, you should see the reading in the viewfinder.
It goes from 8s to 1/30 in yellow
From 1/60 to 1/500 in green
Above 1/500, you wil see a red arrow in the lower corner in the left.
Below 8s, you will see a red arrow in the lower corner in the right.
If the number is blinking, your are in the M mode, otherwise, you arre in the A mode.
This feature, mean metering activation will not work if the meter is off. But how to set the meter on or off?
Good question!! I knew you'll like this blog!!! So there is the answer.
The A setting is for Automatic function.
The M setting is for the manual function.
So in simple word, the A function will put the camera in an automatic setting. Basically, the AE_II control the camera speed upon of the reading of the metering system. It is an aperture priority metering system, in other word; it will take in consideration the actual aperture value to set the correct shutter speed.
Now the ‘M’ setting. Well... it's the manual setting, not much to say. You can still activate it the same manner as described. It will measure the light, tell you what the equivalent shutter speed is, and still aperture priority. It won't override the speed dial setting, it won't talk to you or hug you or kiss you and don't blame him if something goes wrong.
The last dial and function of the camera: the ISO dial.
The other function located in this dial is the exposure compensation setting. It was highly engineered to confuse everybody, to step back the most experienced photographer to an amateur level as a final point, to take the control of the world. But there is hope fellow readers, there was some alien transcript secretly hidden in area 51 that leaked from those felony scientist circle. It took long before the transcript could be interpreted as follow:
Read as from 2->1/2
. = +2/3 stop
. = +1/3 stop
1 = Normal setting (0 stop)
. = -1/3 stop
. = -2/3 stop
1/2 = - 1 stop
There you go, have fun and enjoy your new old meter.
