Focusing with the Monochrom M

Jono's files are the ones I've worked with. As I said, in perhaps 1% of the image area, where there are textures that are troublesome for debayerizing algorithms, the MM wins.

 

This isn't really something you can jawbone with words - either you can post visual evidence, or you can't.

Leica says 100%; you say 1%.

 

Makes sense to me.

Had the chance to try the MM a few days ago with my SUMMICRON 35 mm (IV),

focused on the glasses of the person trying the TELEVID.

 

Don´t think it helps in this discussion with the few pixels you can upload here, but the result

- I feel - is splendid ...

However 18mps are 18mps and the resolution is the same. I repeat, they are just better 18mps.

Resolution measures the ability to resolve fine detail. The number of sensor pixels is just one out of several factors that this ability depends on. In the case of the M Monochrom versus the M9, the M Monochrom has a significantly higher resolution. In my test shots anyway.

In terms of focussing, what impact does that higher resolution have?

 

I recall Lars posting elsewhere that to make the most of this sensor, you'd need a heavy tripod, cable release, no wind or earthquakes and to hold your breath standing 10 metres away (okay, maybe I'm exaggerating a bit, but you get the point). I found this unconvincing.

 

If your image is in focus, and you choose an appropriate shutter speed to avoid motion blur, I see no reason why sharp on an M9 shouldn't be sharp on a Monochrom. What Lars didn't say, and I think he meant, is that because of the sensor's ability to capture finer detail, you will probably need to select a faster shutter speed to ensure that the fine detail is captured.

 

Or have I missed the point?

 

I accept that you also need lenses capable of rendering that detail if you want it, but it does not follow to me that an image taken with my Summilux 75/1.4 on a Monochrom will be any worse than one taken on my M9-P.

There are several factors potentially compromising sharpness, among those camera shake, motion blur, less than perfect focusing, diffraction, and spherical aberration. And then there’s the loss of sharpness due to interpolation between adjacent pixels, i.e. demosaicing. The M Monochrom removes the latter factor, thus adding importance to the others.

Absolutely.

The higher base ISO and better noise performance should offset the camera shake and motion blur aspect. In fact, I am mildly surprised Leica did not reintroduce the 8000 shutter on the Monochrome .As for lens aberrations, those are not user-influenced. It may well be that the camera will bring out the character of certain lenses more effectively.

I am mildly surprised Leica did not reintroduce the 1/8000 shutter on the M Monochrom.

I am glad they didn't! A shutter capable of 1/8000 s means more noise and less longevity.
