...Leica does provide a nice meter in the camera which takes the guesswork out of exposure.

 

This is so since the M6 came out in 1984.

Does the newest M 240 model provide Matrix metering?

I ask this here, rather than in the first section with its higher viewer rate.

The M (Typ 240) offers matrix metering and spot metering, besides the classic central-weighted average metering. But unlike the classic mode, the two new modes will meter off the image sensor. So when firing a frame in matrix-metering mode, the following sequence of actions will happen (even when not using live view):

 

  • close the shutter (which was open for metering off the sensor)
  • half-recock the shutter and reset the sensor
  • open the shutter for exposure
  • close the shutter to end exposure
  • fully recock the shutter
  • open the shutter to continue metering

Well—I prefer the classic metering mode.

 

And what's half vs full recocking? The focal-plane shutter has two curtains. When firing the shutter, the first curtain will move out of the way to start exposure, then the second curtain will follow the first to end exposure. After that, a full recock is required. However when exposing the sensor for live view or matrix metering (as opposed to taking a picture) then only the first curtain will move up and down which requires only a partial recock.

So when shooting with Matrix metering the shutter closes, opens and closes again?! + The sound of the motor to do this.

Blissful for the lucky buyers, who hear it for the first time, after doing an Youtube unpacking for the record. I should look - and hear there first btw.

 

Better not compare that to the (sound?...no) silence of a X100S, A model, latest Ricoh, Sony FF slow-focus-device or... Fuji GF670(W) or... latest telephones.

Curiously enough, matrix may be chosen in "classic" (as opposed to "advanced" or "live view") mode as well and the shutter noise returns to normal then. Not sure what difference it makes if any though.

The menu structure is poorly designed. When in the main menu the Classic light-metering mode is selected then, in the Set menu, any option besides Center-weighted will make a difference only when shooting in live-view mode.

 

In other words—when in Classic light-metering mode and not using live view, the metering method will always be Center-weighted, no matter what you've selected in the Set menu. So when you're not using live view and still want to use either Multi-field (= matrix) or Spot metering then you must select the Advanced light-metering mode in the main menu. However I'd recommend against using the Advanced light-metering mode because it will drain your battery and stress your sensor.

 

And oh, by the way—I made a mistake in the description of the sequence of actions above. The half recock will happen right after opening the first shutter curtain for multi-field metering or live view, not after closing it. Closing will be just a faint "click". Opening is "click-zzz".

The shutter sound of the M Typ 240's that I've heard (including re-cock obviously) have been very quiet and imho very similar to my M2...

Difficult to compare with film Ms but in classic mode, the M240's shutter+motor noise is similar to the shutter noise alone (excluding re-cock) of the M8.2 in discreet mode. Sounds a bit more damped than the latter though.

New, more quiet shutter ?! :)

Better high ISO, faster processor & buffer: :) , :) .

I'll look at it around Christmas then.

Normally I don't care about a new model during the first 9 - 12 months. Got my two M8 one Photokina later, end of 2008.

Only one here now, because it's mostly M6TTL for me. We'll see. Anyway, just a guess: why would something called mini M be FF? We'll know soon :cool:

Back to the subject: 2/75 IQ is great at all distances imo. But I regret having sold the 2/90A because its longer focus throw is a big focussing advantage.

Hi to everyone

 

Recently got the 75 Summicron, that i ordered. Waited a while for it to arrive.

The images look good with this lens. I also considered the Summarit, and liked it for its dimensions.

I decided to get the Summicron, because its faster, and focus closer.

 

I however have noticed a roughness in the closer focus(when focused around the closet point distance .7m this does not always occur, but can be really concerning when it happens. Only noticed this this morning(first time it happened). most of the time the focusing is smooth, but then I encountered this this morning?

I wondered if anyone else have anything to say, or have experience this with any of their new Leica lenses?

 

Kind Regards

Yes, I had a similar problem with a 75 Summicron bought in April. The focussing action would bind slightly around the 0.75m mark; enough IMO to interfere with accurate focussing. Leica Mayfair sent it back to Solms and it is now smooth and consistent throughout the whole focussing range.

Few minutes ago I was unscrewing the polarizer from the Cron and the front threads ring came out from the lens.

As I didn;t screw the polarizing filter to it hard it was easy to unscrew it from the lens thread ring. I was ablte to screw the lens thread ring back to the lens.

 

Shold the lens go to Solms or the unscrewing front threads is something that just happened and after I put it back I should not worry about it?
