Marty Posted January 15, 2010 Share #2  Posted January 15, 2010 It is explained in the brochure: Exposure metering: Exposure metering through the lens (TTL), center-weighted with working aperture. Center-weighted TTL metering for flash exposure with system-compatible SCA-3000/2 standard flash units. Measurement principle: Measured by light reflected by bright shutter blades on the first shutter curtain. The reflected light is measured by a photodiode below the lens mount. I guess it is comparable to the D3's center-weighted metering mode except for the exact shape and weight of the central area which for the M9 looks like a squashed oval covering roughly the central 25% of the view, and is fixed. I am sure someone has more precise figures. Link to post Share on other sites More sharing options...
stunsworth Posted January 15, 2010 Share #3 Â Posted January 15, 2010 Think of it as a fat spot meter rather than centre weighted. Link to post Share on other sites More sharing options...
jaapv Posted January 15, 2010 Share #4 Â Posted January 15, 2010 The best way to use it is to go to manual and measure the darkest and lightest areas of the image and determine your exposure accordingly. Refer to the manual for the use of the red triangles in the viewfinder. If you are lazy just go to "a" and trust the camera..... Link to post Share on other sites More sharing options...
stunsworth Posted January 15, 2010 Share #5 Â Posted January 15, 2010 If you are lazy just go to "a" and trust the camera..... Â I'm lazy, I point the camera at a midtone - such as grass for example - and lock the exposure on that. If the light is difficult, then I agree manual with some educated adjustment is best solution. With the amount of snow we've had in the UK recently I overexpose to prevent everything looking grey. Link to post Share on other sites More sharing options...
jaapv Posted January 15, 2010 Share #6 Â Posted January 15, 2010 I'm lazy too from time to time, Steve:o. Strangely I find myself going to manual more often on the M9 than on the M8. Maybe because the soft-release inhibits AE lock. Link to post Share on other sites More sharing options...
david berry Posted January 16, 2010 Author Share #7 Â Posted January 16, 2010 Advertisement (gone after registration) Thanks Jaap and steve for your great responses...How do you guys hold and lock an exposure once you have metered and than recomposed the picture ?? Do you hold half way down on the shutter buttom? Link to post Share on other sites More sharing options...
jaapv Posted January 16, 2010 Share #8 Â Posted January 16, 2010 Indeed that is the way to do that on the M8 and the M9 in standard mode - again I must point you to the manual.... Link to post Share on other sites More sharing options...

The leica metering system works very different than a Nikon D3 or other DSLR's system...Trying to understand how to meter different situations..Thanks for your imput  I don't know about a Nikon D3, but, somewhere deep in the darkest depths of the menu system, I have managed to make my D700 shutter button work like an M7's... And just like an M9 will do. The D700 also gives three different metering patterns. Maybe the D3 does too.  Take a meter reading, hold the button down half way to lock it, recompose and shoot. Intuitive, simple, and works very well, on both the M7 and the D700. Link to post Share on other sites More sharing options...
Jeff S Posted January 16, 2010 Share #10 Â Posted January 16, 2010 To state the obvious, remember to focus where intended, not necessarily where you meter. Â Jeff Link to post Share on other sites More sharing options...

Set this to 'On' and the exposure will lock when the shutter release is pressed halfway. You can also adjust the size of the centre-weighted area to more closely match the pattern of an 'M' camera by using custom setting B5. Link to post Share on other sites More sharing options...
