[QUOTE="J-see, post: 367644, member: 31330"] Perfect exposure is probably an ideal that won't be possible in reality. Thinking about it, it's not necessarily light metering. Anyone with two different cams can test it, same settings, same lens, same shot. The RAW files should be close to identical. If not, either light metering differs and 18% grey means something else for each cam or the translation of what is captured is different which means, each different sensor has a different output. The problem is that if different cams have a differently exposed shot, only one of them is correct (or none). The rest is either slightly over or underexposed. Now even when, that's not what I have issues with. Slightly too bright seldom is a problem. It needs to overexpose quite some to have white noise appear which can no longer be corrected in post. Underexposing is something else; dark noise appears rather quick and doesn't disappear when correcting exposure in post. Which is why I only compensate exposure to brighten. But the main issue is that when I try to shoot at the "end", it warns about underexposure while the shot is perfectly reasonable (for the conditions). It's too early and I can't rely on the cam. The only option left is take a shot, check, correct or not and try again. Rinse and repeat. That annoys me but I learned to live with it. Yet I'd be a happy bunny if I could adjust the warning levels until they match the "real" limit. [/QUOTE]
