EOS R exposure compensation and metering

I just noticed that the exposure compensation on the EOS R seems to be limited to +/- 3 stops. I know the situations where you would really want to go beyond either of those limits is rare, but I'm a little disappointed as you can push the exposure compensation right off the end of the scale that's shown and keep going if you really want to on the 5D4.

Also, is it just me, or is even the evaluative metering mode on the EOS R weighted to where the focus point is? I know we have wanted this feature for a long time, but it doesn't appear that there's any way to turn this on or off. It seems to always weight the exposure based on how bright it is where the focus point is.

Exposure is not linked to focus point, but my SL-2, 5D MK IV, and EOS R all adjust the lighting in live view once I select a focus point, so it appears that it exposes for the focus point. Actually, It is not adjusting the exposure until the camera is focused.

3 stops of EC is normally plenty, but I can see that there are cases where it is not enough.

This has been annoying me also. I want a camera that meters the whole image and then focus where I want. The R has a great metering that’s somewhat ruined because it heavyly weights towards the AF point... I wish I had that as an option and also a complete average independent of the AF point... I do A LOT of EC I should t have to...

Ok, so both of you just said completely conflicting things. Which is it? :unsure:
Spot metering is NOT linked to AF point, but the average metering IS weighted to the AF point. If I meter a scene with center point and it gives one exposure, without changing framing or anything but AF point placement, the metering shifts towards getting what I focus on, properly exposed.

Evaluative metering changes the exposure depending on your AF point (It's evaluating, after all!). If you don't want the metering to change with your AF point, it seems as if you should use partial or center-weighted metering.

Having owned mirrrorless for a while now, it seems like your settings are far less important than with a DSLR since you can see your metering in the EVF.

Well, I don't know about less important, but thing for me is that I constantly have to adjust EC where I should be able to see through the EVF the exposure I want and then concentrate on AF, now, in a burst suddenly the metering has changed a lot when I don't want to.....

I think you mean evaluative, rather than average. Yes? Evaluative analyses the whole frame but weights for the area under the active AF point/s. Spot, partial and centre-weighted average are not linked to AF point. Those modes all start with whatever is in the centre of the frame, and the difference between them is basically how far from centre they take into account.

Personally I use centre-weighted average most of the time. You can get a pretty good feel for how it will meter if you look at the whole frame, so you have a pretty good idea about what EC you need for your subject. I find evaluative is “inconsistent” in that a small change in the scene can sometimes cause the camera to analyse a scene quite differently and select quite different exposure settings, so it’s hard to anticipate what EC you will need.

Correct, I mean evaluative, sorry ‘bout that (y)

Ok, I simply cannot get this thing to meter properly in low light, indoor situations. Seems to be either way too bright or way too dark, depending on what metering mode I use. On the 5D4, evaluative metering always seemed to work pretty well. With the R, it's just erratic.

What is the metering mode on the R that is closest to evaluative on the 5D4? Center weighted average? Evaluative on the R just doesn't seem to act the same.

I think metering so far is the same or better than my 5D MK IV. Accuracy is very dependent on the scene, if the subject does not fill a lrge part of the screen, then center weighted or spot may work better if the subject is in the AF area. I have only taken about 500 shots so far, so I really have not used mine in a lot of different lighting situations.

The histogram reads the whole scene. This is the first camera where I don't even use the in-camera meter. Every once in a while I check where it's at and it seems accurate enough, but I'm not using it.

I guess I'll have to try Av mode (or auto ISO in Manual) and play with EC a bit. But, I thill think I'll just monitor the histogram while changing EC.

I can't believe how much of the shooting experience is different with the mirrorless camera. So much more to learn and so many habits to unlearn.
