Advertisement Posted May 19, 2011 Posted May 19, 2011 Hi pico, Take a look here What's the function of this window?. I'm sure you'll find what you were looking for!
efix Posted May 19, 2011 Share #2 Â Posted May 19, 2011 This question has been asked about a milliont times, and I am sure that with a little internet research you could've fount your answer. (Maybe you will want to catch up on that.) Â In short, it measures the ambient light, compares it to what the metering cell meters through the stopped-down lens, and by that calculates the aperture that must have been set on the lens. This way, the EXIF data from M8/M9 files tells you a "guesstimated" aperture value. Link to post Share on other sites More sharing options...
01af Posted May 19, 2011 Share #3 Â Posted May 19, 2011 Inofficially it's called the Blue Eye. Behind it, there's a light metering cell. The comparison of its value to that of the TTL metering provides the data upon which the aperture gets guestimated. Link to post Share on other sites More sharing options...
jaapv Posted May 19, 2011 Share #4 Â Posted May 19, 2011 And it measures ambient light for the M-TTL flash mode. Link to post Share on other sites More sharing options...

xrpix Posted May 19, 2011 Share #6 Â Posted May 19, 2011 one told me it is also involved in the White balance evaluation, is he wrong? Link to post Share on other sites More sharing options...
zlatkob Posted May 19, 2011 Share #7 Â Posted May 19, 2011 Advertisement (gone after registration) I've never ever seen it asked and if you don;t know what it is called or what it is for, then how do you search for it? Â Agreed. I don't know what "little internet search" would have found the answer. Try googling for it when you don't know what it's called or what it does. Â Fortunately it is in the manual. The inside cover has different views of the camera, and there is a "Designation of parts" page. On the front view, this window is labeled 1.4 Brightness sensor.

pop Posted May 19, 2011 Share #10 Â Posted May 19, 2011 Not that I'd mind it being asked here or wherever, but don't you folks look into instruction manuals? The window is depicted on page 2, labeled as "1.40". On Page 8 it says what the window is called and what it does. Link to post Share on other sites More sharing options...

ayewing Posted May 19, 2011 Share #12 Â Posted May 19, 2011 I never mind people asking easy questions. I was a bit slow in noticing this thread so I missed the ego boosting opportunity to air my superior knowledge. Link to post Share on other sites More sharing options...
earleygallery Posted May 19, 2011 Share #13 Â Posted May 19, 2011 It was meant to have been for an AF assist light, but Leica decided at the last minute to stick with manual focus. A lot of top plates had already been milled so they had to invent some other purpose for it, and decided upon the brightness sensor. The other design option was for a small protruding 'reading lamp' so you could see the lens markings at night. Link to post Share on other sites More sharing options...

Washington Posted May 20, 2011 Share #15 Â Posted May 20, 2011 I think it quite impolite to hassle a guy with an honest question. What are we here for? To tell people to go elsewhere? Quite frankly, I did know myself because I had never given it any thought. Now I do and I am glad. Link to post Share on other sites More sharing options...

If you win, there is no honor and if you lose you will never live it down.  The M9 is back and better than new. Leica USA rebuilt it and returned it in 10 days. My ribs feel better and I am off the cane. I was well enough to shoot some pictures with the M9 last week at my mother's funeral ceremony.
