Canon 1N Metering Sensor and Focus Screen

[victor_zhou]

I just bought a Canon 1N. And to my curiocity, is there someone who

knows where the metering sensor is mounted in the body?

 

On the other hand, I may replace the focus screen. For this woke, can

I do it as DIY, or I have to send it out to have Canon service to do that?

 

Thanks,

 

Victor

If you mean the EOS-1N you can change the focusing screen yourself, it will take about 10 seconds.

How to change it? I haven't found any instruction to change the focus screen on the manual.

 

Thanks,

If you by a new replacement screen, they come with instructions and a little plastic tool to unlatch the focus screen holder and to use in grasping the screen for removal and replacement. There is a little "tab" on each screen that is used for the grasping.

<p>The ambient metering sensors in EOS bodies are mounted somewhere in the area of the pentaprism (or pentamirror, for cheaper bodies) assembly, and they read light as it hits the focus screen - which is why some bodies with interchangeable focus screens have a custom function to adjust metering if you use a brighter or darker focus screen.</p>

 

<p>The flash metering sensor is located in the bottom of the mirror box and reads light off the film during exposure. Some newer bodies can use the ambient metering sensor for flash metering with an appropriate flash unit; the 1N is not one of these.</p>

Thanks all of you for your helpful answers. I know much more about my camera now. Best,
