Is the EM5’s Miss-Stated ISO concerning to you?

Here are the arguments.

On one side:

Iso doesn't matter. It's a bourgeois concept.

I'm going to spew some technical gargon that will confuse you about jpeg gain and dxo measurements of saturation blah blah blah. raw doesn't matter blah blah. confuse the reader even more so they are convinced they don't need to care about overstated iso

Omd is god. Don't you dare talk bad about it. Everything they do is right.

On the other side:

I want some to compare cameras with an even baseline exposure. If the stated iso isn't similar than I can't make fair judgements using image comparison tools.

Here is the simple solution for dpreview: Iso does't mean anything. It's all about the exposure.

1. use a constant f-stop.

2. instead of iso split out the images by shutter speed.

3. use a controlled lighting setup measured by a light meter.

It's so easy. Comeon dpreview. Your (raw) comparison charts are flawed and favor overstated iso camera.

btw I've did test comparing the d600 and the fuji x100. The fuji x100 is definitly overstating their iso by 2/3 of a stop. This is exactly in line with the dxomark iso sensitivity measurements. I really trust their methods.
