M8 vs M9 Sensor comparison

Hi all

Im doing some research about a possible upgrade and I was wondering how the sensors compare , looking at the sensor size difference it appears that the M9 has 80% more resolution, but also 80% more area, so wouldnt the respective pixel/square MM be comparable?


area of sensors

m8 : 18 x 27 = 486 sq mm
m9 : 23.9 X 35.8 = 855.62 sq mm

MPixel : M8 : 10.3 vs M9 : 18.5 (which is approx 80% larger)

80% larger of 486 sq mm is..........874.8 sq mm quite close

I do know that of course a newer sensor has better technology re: IR filters and higher ISO

but looking at the actual numbers, Im thinking I might be better off with some additional lenses instead of a new camera body. Which will guarantee that my M8 will die right afterwards

Resolution is linear measurement, not an area measurement. So the difference in resolving power would be the square root of the pixel resolutions divided by each other. You are getting a 34% increase in resolution.

The area of the sensor will effect the field of view, depth of field, and the system MTF. Your lenses will not have to work as hard with a larger sensor.

Robert,

Have you thought about trying to do pseudo* near IR or near UV?

*No real near IR is possible with the M8

Hi Dude,
It will be interesting to see the replys as I am in the same boat. Jean at Leica Boutique in Montreal was of the opinion that there was not that much differernce and suggested I was just as well off with a used M8 and an extra lens.

Prices might come down depending on May 10 announcement and the 800E is also looking like an alternative considering one could pretty much buy one for the difference in proce between M8 and M9.

I think the proof is in the prints and would love to hear from those that have printed with both - is there a enough of a differerence up to 24 x 16 to justify an M9?

Without quoting all the technical foofawraw, my 1st-order estimate was that if I shot a photo with an M9 and cropped it to the area of the M8 sensor, I'd end up with the same number of pixels as the M8 and about the same overall dynamics. On that basis, I was interested in the M8.2.

However, in the end I bought the M9 because I wanted the same format I had with the M4-2 and the M9 has enough other detail refinements that it was worth going that route for me.

Good points Godfrey , I fear with my financial situation a M8u will have to be it for me Im afraid . Im just trying to convince myself of that :)

If I didn't have the money for an M9, I'd have no problem at all enjoying an M8.2. If I couldn't afford an M8.2, an M8 would do fine. If I couldn't afford that.... well, I've kept on doing photography with far less expensive cameras anyway so I'd just wait until I could afford something. ;-)

I know many saw it different but personally I allways liked the M8 and never saw it as a flawed product.
The step from the M8 to M9 meant to me:
Some room for bigger prints.
Improved noise in the range higher than 640 ISO.
No crop factor. No UV/IR filters (no big deal).
But if the resolution is enough and if you dont plan to shoot over ISO 640 I would say one gets the same IQ with the M8 which you can get with the M9.
I think for B&W the M8 is even a little bit better suited.
If I couldnt afford the M9 I would be happy with the M8.

The M8 had been for a year when I bought mine (now 4 1/2 years old) and 15K images later, it has never missed a beat.

I am extremely happy with it's performance, and when this new M10, and the subsequent drop in prices for M9's happens, I will have to think long and hard about whether it makes sense to trade up.

The UV/IR filters are only a problem in night photography with extremely bright lights in the image. For daylight shooting I have never had a problem.

For B&W work, there probably is no better digital camera than a M8/8.2.

I recently bought another M8, I've had 3 to date and loved them all, the file quality I get from the M8 is for me significantly better than what I ever got from the full frame 5D or D700. I was seriously considering getting an M9 and tried one out, but when looking at the Raw files from the M9 I didn't get the same feel, I expected them to be brilliant but found them full of moire and lacking the signature I get from the M8 files. Not sure if anyone else has found the same thing, I might be out on my own with this one.

Between the M9 and M8, "Pixel-Peeping"- the M8 image looks "crisper".

The IR absorbing glass filter is thicker on the M9, which is the reason that it does not need an IR reflecting filter in front of the lens. I've read other users attributing the crisper images of the M8 to it's filter being thinner than that of the M9.

I agree with you about the moire. The M9 seems much more susceptible to it than the M8 (which is odd because they both have the same pixel pitch and use the same lenses). The M8 files do also seem a hair sharper at the pixel peeping level. All told, however, I prefer the M9 for its full frame compatibility with my film Leicas and for the 'soft' release mode.

Hmmm - not convinced about the moire . . it's so rarely a problem that I doubt it's easy to get a handle on what's 'worse'
I didn't get the feeling that the M9 files were less sharp - but I can see the logic with the stronger filter.
I think the M9 has slightly better high ISO, but I agree, if you don't mind the crop factor and you don't need the resolution. . . .

I do think the M8 is better at black and white . . . . but the M9 isn't bad.

I guess that isn't helpful at all!
all the best with your decision

What is the consensus around ISO?
I only shoot the M8 @ 640 in a pinch, though 320 is perfectly fine to my eye in prints.

Is the M9 a 1 stop bump? 2?
For people who have owned both - what were your relative ISO comfort points?

I kinda like the "defects" that come with the M8's sensor... I find that the images it makes are almost as nice and have the feel of nicely exposed, developed, and scanned film. A guy I met described it as a "the most film-like digital camera" he's ever used. It's got a certain grit to it. I find that the M9 is almost too perfect... too clean. I feel like your vintage lenses would be better suited to an M8 :p If only it were a full frame sensor huh?

I'm surprised you think this, Jono. I see moire (the classic 'stripe' variation and other lesser or worse manifestations) all the time. I wouldn't describe it as a problem (otherwise I wouldn't have bought an M9P earlier this year) but nor would I describe it as a rare occurrence (I probably see moire-ish artifacts of some kind in 20+% of my files).

I think you mean with the M9. The M8 is more sensitive to IR.

With the M9 you can shoot with large aperture lenses in IR during the day, and with a tripod if slower than F/2.0. I do this regularly.
eg.

Subtle, but the glasses are black framed in visible light.
Colour is below.

The M9 certainly has a good stop's worth in terms of lower noise but I get the impression that this is at the cost of a little detail. I routinely use up to around ISO 1000 (even higher if necessary for personal stuff) on the M9. With the M8, I used to see ISO 640 as the upper comfort point.
