“Hi Peter,

I love your site and the pictures that you post.  They are a great inspiration for me to get better at being a photographer.  I follow your blog and have been very curious about the M240 and M9 debate, or the CMOS and CCD sensor battle.  I have an M9 and have been thinking about moving into the M240.  Mind you I have only been shooting Leica for about a year now.  But when I see your images and read about what you have to say about the CCD.  Then I don’t want to get the M240 anymore.  Part of the reason why I would like to get the M240 is to be able to use the higher ISO for when shooting at lower light situations.  Anyway, I’m still holding on to the M9.  Any tips on what to do when shooting in lower light with the M9?

Keep up the great work!

Cheers,
Kerwin”

Hello Kerwin,

First of all, thank you so much for your nice comments.

Now, to address your questions, which are all excellent…

Yes, I’ve always believed, and continue to believe, that CCD sensor cameras produce images at base ISO that are more pleasing than CMOS sensor cameras.  However, in low light, CCD sensors struggle relative to their CMOS counterparts.

The introduction of the Leica Monochrom did much to close the performance gap, but of course you’re limited to B&W photography when using this camera.

Quite simply then, if you wish to continue to photograph in low light situations using an M9, you need fast (aperture) lenses, like the Summilux (f/1.4) or even Noctilux (f/1 or f/0.95) lenses.  If your subjects are relatively still, then of course a steady hand and slow shutter speed are very useful (as are monopods and tripods, but most of us who shoot rangefinders do not make use of such additional equipment).

It’s also critical to expose properly with the M9 when shooting in dark environments, especially when employing high ISO.  This can be a problem, since I rarely feel comfortable shooting above ISO 1250 with this camera.  Others limit their maximum ISO to 640 and then “push” the exposure up during image post-processing.  I do this frequently.

I said above that your questions are excellent, which is very true.  It turns out, however, that your questions are timely too…

I have decided to purchase an M240.

–

I know I will be sacrificing low ISO image quality, in the form of the “crispness” I currently see in my images, but I am willing to give the M240 a try.

Why?

Most of the time, the light in Toronto is poor, as the winters here are long and dark.  Having a camera that can comfortably shoot above ISO 1250 has increasingly become a priority for me.

And, after selling off most of my equipment over the last few days, I’ve decided I don’t want a Nikon D800, or Sony A7/A7R, or an Olympus E-M1, or Fuji X-E2.

No folks, I still want a digital rangefinder (please see the previous post, Rangefinder Cameras)

And as far as digital rangefinders go, there’s still only one game in town.

—Peter.

The longest running CCD poll :), asking whether a brand new CCD sensor should reappear in a future Leica M camera, is still running…

Why am I continuing this?

Because I love the rendering of CCD sensors!  The Leica M9 is like a portable digital mini-medium format camera.

At the very least, CCD sensors offer us photographers an alternative choice.

I’ve noticed a few notable individuals who were initially very enthusiastic about the Leica M240 (CMOS sensor camera) have now changed their tune and are subtly conceding that the M9 image quality at low ISO is superior.

So far, I have just over 400 votes…

—Peter.

I once wrote:

The first manufacturer, other than Leica, who places a 24 x 36 sensor in a mirrorless interchangeable lens camera can count me in as a customer.  I have no doubt that at some point, somebody will do it.

However, the insanely loud shutter on the A7/A7R is a deal-breaker for me.  You can listen to it in this field test video (courtesy The Camera Store) at approximately 5:22 into the video.

The EVF is already dated too.

Too bad.

Still, you have to give Sony credit for shaking the industry.

So far, after 125 votes, I’m surprised to see the overwhelming majority of you do want a CCD sensor in a future Leica M.

(By the way, you may still vote.)

Most of the internet fora discussions would have you believe that opinion is evenly split, or perhaps favours the new Leica M(240) and its CMOS sensor.

I know that the sample size of this poll is extremely small, and there may be selection bias at play (i.e., those who follow this blog may be biased towards favouring CCD sensors) — which makes the results tenuous at best — but the results are intriguing.

Perhaps things will equalize as more votes are cast.

—Peter.

As most of you know, I’ve been very vocal about my preference for CCD vs. CMOS sensors…

…but it looks like the Leica M9/M-E and Monochrom are the end-of-the-line models for 36 x 24mm CCD sensor technology.

Nonetheless, I thought it would be fun to conduct a poll about this, here on Prosophos.com.

Essentially, I’d like to know whether YOU would like to see Leica bring back a new CCD sensor in a future M camera, optimized with whatever current technology exists.

Please vote and voice your opinion, but remember this is just for fun.

I was surprised to see that above is still the most popular post on Prosophos.com, given I posted it three months ago.

Leica M9 vs. M240

Yes my friends, I guess the CCD vs. CMOS sensor debate rages on… for many.

Not for me though.

Leica M240: Final Verdict

Leica M9 sharpness vs. Sony RX1R, Nikon D800E, Fuji X100s

Recently, I asked the question:  How large a print can you make from a Leica M9 file?

For my purposes (portraiture and simple element scenes), the answer turns out to be 36 x 24 inches:

I thought about this some more, and realized that it would be interesting to see how much of a magnification over the Leica M9 sensor those prints above represent.  If you want to skip the math below, the answer turns out to be 645!

Here’s the math:

The Leica contains a so-called “full frame” sensor that is exactly 36 x 24 mm in size (that’s where the 36 x 24 comes from).

The area of this sensor

= 36 x 24 mm

= 864 mm²

 –

The prints I made were 36 x 24 inches.

In the equivalent (metric) mm, this translates to

= 914 x 609.6 mm

=557, 174.4 mm²

 –

The magnification of print-over-sensor area, therefore

= 557,174.4/864

= 645

–

This is remarkable when you think about it.  The digital sensor (about the size of a stamp — remember those?) produces an image which is then magnified 645 times to produce the prints you see above.

Proportionally, this is what is going on:

All of the above underscores the importance of technique, lens quality, etc., when photographing with the aim of producing large prints: any “error” will be magnified 645 times!

Of course, you always have the option of turning to the much larger and more forgiving medium format sensors, but that’s another story…
