Nikon FM how to correctly use the light meter
Hey everyone,
I just picked up a Nikon FM with a 50mm f/1.4 lens, and I'm currently test shooting a roll of APX 400. I'm coming from a digital background, so film metering is a bit new to me, and I’m getting some conflicting advice that has me totally confused.
* **Person A** tells me that the camera automatically accounts for the aperture when I turn the aperture ring, so the light meter inside the viewfinder adjusts dynamically.
* **Person B** tells me I *have* to push down the depth-of-field (DOF) preview button while looking at the meter to get an accurate reading.
Which one is it?
To make matters worse, I was testing it outside just now. With the camera set to **ISO 400**, I chose **f/16** and cranked the shutter speed all the way to **1/1000s**. Even with those maxed-out settings in broad daylight, the meter is *still* indicating that it's overexposed (+).
According to the sun f16 rule, ISO 400 at f/16 should give me around 1/400s or 1/500s, so 1/1000s should definitely not be overexposed.
Am I doing something wrong with the meter? Is the lens not communicating properly with the body, or could the meter itself be broken?
Any help would be massively appreciated!
