Larger sensor please

When will Leica or any other manufacture realize that its the size of the sensor not just the megapixels that matter - certainly for noise. I was very interested in the new V Lux until I read about the sensor size of the camera. I would be more interested in an 8 mp camera if it had a larger sensor. At lease that way I could shot at higher than iso 100 levels.

The sensor in the M8 is smaller than full-size 35mm (24x36mm), but larger than all other sensor size classes:

 

Sensor Size (mm)

Type Width Height

1/3.6" 4.00 3.00

1/3.2" 4.54 3.42

1/3" 4.80 3.60

1/2.7" 5.37 4.03

1/2.5" 5.76 4.29

1/2" 6.40 4.80

1/1.8" 7.18 5.32

1/1.7" 7.60 5.70

2/3" 8.80 6.60

1" 12.80 9.60

4/3" 18.00 13.50

APS C 23.70 15.70 (also called 1.8")

35 mm film 36.00 24.00

 

The M8 sensor is 18x27mm, larger than both the 4/3 and APS (or 1.8") sensors.

 

The sensor in the D2 is a 2/3" sensor (6.6x8.8mm). I have a 13x15 inch print made from a section of the image that is about 1/10 of the captured image. I make that a 13x15 print from a 1x1mm sensor! It's "grainy" looking, but fully clear and has good color saturation and accuracy.

 

I also have 13x20 prints from roughtly the full size image at ISO 400 (not the D2's best offering) and these are stunning pictures (I'm talking about print dynamics, not aesthetics).

 

I have no problem with the images from my D2.

 

And, not to steal Sean Reid's thunder, his review rates the image from the M8 very highly, even in comparison to images from full-size sensors.

 

As we used to say in our 3rd grade book reviews, "If you want to see how the story comes out, you have to read the book." It's not about sensor size -- It's About The Lens. A lousy, low-noise image, is just that, lousy.

 

If you are a Leica lens user, you've already achieved Nirvana. What I am anxiously awaiting in my M8 (what time IS it?) is not primarily the larger sensor, but the LENS! I'm waiting to put a r-e-a-l lens in front of my digital capture.

A small sensor is part and parcel for a super-zoom camera like the V-Lux. It's the only way to get a "35-432mm" zoom into such a small package. Make the sensor small so that the long end of the zoom is only 72mm in real focal length (cropped 6x to get the effective "432mm" look).

 

Samsung's super-zoom camera uses a 2/3rds sensor, but is quite bulky compared to the PanaLeicas.

 

Not that I disagree with your basic point - I tried an FZ10 for a while, and even limited to FOUR megapixels it was too noisy for me except at the basic ISO 50 (and even then...)
