Aperture Priority with M10-P

Been using my M10-P mostly in aperture priority today as I’m quite used to that with the Fuji X cameras I use. I did find that the images shot are quite dramatically under exposed, nothing I can’t fix in C1 but a bit frustrating all the same. 

As a guide I also took a couple of images with my X100f in AP and found these to be nowhere as under exposed as on the M10-P, wondering if this is normal behaviour for the M10-P.

Two probable explanations:

- The M10-P uses centre-weighted metering (unless you deliberately set it to spot or multi metering where the shutter is kept open and drains the battery) which meters off more of the scene and can take into account brighter objects that you might not be expecting and accordingly lowers the EV.

- Check that negative exposure compensation hasn't been dialled in.

Thanks for the reply. No negative EC dialled in. Looking at the photos, I’m guessing as it was quite a sunny day the metering was compensating for the highlights and dragging down the shadows quite aggressively. More so than the Fuji camera I also had with me.

Have you compared your M10-P's exposure reading with a hand-held light meter to find out whether it's accurate?

Hi Dave, What you are describing is normal for the M10-P. It behaves like the M9 in that it underexposes when there are strong light sources in the frame. Unlike the M9 though, its ISO values aren't equal to a traditional film ISO. Its slightly inflated so if you compared your reading to that of a handheld meter it would be off by about a stop.

Leica started inflating the ISO values starting with the M240. I would suggest that in AP mode move the center of the frame around the scene until you find a reading somewhere between the highest and lowest readings then half press to hold, recompose and shoot

I haven’t actually Pete, I may give that a try actually just to give me some sort of idea.

Thanks for your advice. Seems the best option or trying to shoot more in manual than I do. I’ve always shot digital in AP so it’s just second nature to do so in truth. 
 

The good thing is there’s plenty of shadow detail to drag back so all is not lost 😂

Exactly!

This image was overexposed by a half stop in order to capture some of the brilliance of the sunset colors. I still had to open up my shadows by about a half stop in Lightroom to pick up the greens in the grass.

By the way, I saw your images with the Summicron-C. very nice!

That’s very nice man. 

That little 40mm Summicron is a belter for the money has to be said.

Oops! I just realized that I put down the wrong lens. This is actually the 28/2 ASPH, v2.

But I agree, the Summicron-C is a steal. What I do love about the 50/1.4 ASPH is that its like a chameleon in that its character changes very quickly based on the kind of light, how close you are to your subject and what aperture you are using. I bought mine about 6 years ago and its the one lens I've held onto throughout all the horse trading I've done.

Ah, I’m with you. I’ve considered a 28mm as I think it would make a good landscape lens for me, but haven’t done much about it as yet with all that’s gone on this year. 

I also have the 50mm f2 ‘cron which I’m very happy with - I’d like a nice quality 35mm I think next, I have a cheap 7artisans but wide open the bokeh is pretty funky.
