Low exposure w/Summilux-50 + M9

[Cranialpush]

I've just returned to the fold (so to speak) having purchased an M9, some two years after deciding to sell my M8. So far I'm amazingly pleased! However I've noticed that using a Summulux-50 I seem to be a stop down (-1EV) on exposure than when using either a Summicron-35 or 90, both of which I would say are exposing correctly if perhaps a little bright.

Just curious as to thoughts of if it's an M9 thing as I don't remember it from the M8.

Thanks

I have had similar issues with various leica lenses, but usually the older lenses. For me, it wasnt so much a difference in the camera metering ,as it was a difference in what the lens aperture purported to be versus what the actual metering was. Eg, is the Lux a truef1.4? Is the Cron a true f2.0?

I would say to dial in some exposure compensation if you feel your lens is producing 'dark' photographs.

Unusual. In general the M9 preserves highlights better than most digital cameras, producing images that <seem> to be too dark. They are not- the ISO norm leaves the camera manufacturer latitude in determining exposure on a sensor, unlike film. If you find your images too dark for your taste, do not correct with the exposure slider, but by using the fill light, that gives better results - always assuming that you exposed correctly in the first place. As a comparison, many M8 users dialled in a 1/3rd or 2/3rd exposure compensation on the M8. On the M9 - don't. You can, however, dial in a plus exposure compensation on low-contrast subjects. Check your histogram.
