How do do

[Annibale G.]

How do you measure exposure with 24 and 21 mm lenses with M system?

[earleygallery]

Same as you do with any other focal length. Use built in meter if its got one or a handheld/sunny 16 rule, and meter accordingly depending on the scene (beaches/snow allowing for compensation etc)

Or use a handheld meter. I like using incident readings with the realy wide wide angle lenses rather than the internal meter.

If you photograph landscapes, and want the soil, woods, houses to be correctly exposed rather than the sky, then turn your camera sightly downward when taking the measurement.

I would suggest 2 methods.

As Christer says, if you're outdoors, you can use pavement or grass as a substitute for a gray card reading. I have found, however, that the M8 meter correctly meters just about all the time, outdoors. It prefers to meter the sky, so if you want lower levels, either adjust manually, or meter your hand.

For shots where people are included, meter your hand or meter a face if you can get there.

I have shot about 1500 pix, now, with the M8, using 24, 35, 50, and 75mm lenses. The M8 meters correctly when not himdered. As an example where manual setting are required: I shoot stage productions, so I find the correct manual speed and aperture settings using the review screen.

Annibale, it would help if you stated exactly what measuring equipment you have at your disposal.

Other posters will tell you what they do, but that is with their equipment. The point is what do you have, what do you shoot with your wide angles, etc. With that knowledge we can give you much more accurate advice, maybe,

Cheers,

Ok. My problem came because I've red somewhere that with lens below 28mm the exposure meter in M7 doesn't work. Maybe I was wrong. I hope so.

I don't have an M7 so can't comment. I use an M4, M6 pre-ttl, and now the M8.

I tested my newly acquired 24mm lens on the M6 to make sure it was ok, while waiting for my M8 to arrive. The M6 metered correctly.

I've been using a Voigtlander 21mm LTM lens with an M adaptor that brings up the 35mm frame lines on my M6. The 35mm frame lines seem to work as a pretty good guide for the metering area covered with a 21mm lens.

Annibale, I use the 15 Heliar on the M6 & MP and it works great
I used it on the M8 for testing and it works great too !
