The Leica M8 Introduction

Scott Kirkpatrick, backlit Leica M8 test shot

by Scott Kirkpatrick

I had two reactions to Mike's somewhat patronizing faint praise for the Leica M8 and his description of its rollout in the DMR post a few days ago.

First, the comparison with Harley-Davidson leaves out a lot that is interesting about the Leica M transition to digital. When Leica went digital it took three steps. There was an S1 technical camera (think of a Horseman with a scanning three-row CCD back) which no one remembers except the folks at New York's Metropolitan Museum, who imaged the back side of the restored Unicorn tapestries, thread by thread, by recording it on an S1 and then creating the world's biggest mosaic. Then the DMR. Finally, they were ready to take the plunge to see if a new revenue stream could begin with the M8.

A digital camera is a computer in back of a lens, encased in a camera body. Leica understands lenses and bodies. Leica marketing must know that all those great lenses are out there, waiting for new cameras to shoot on. But to design the electronics and write the firmware for the stuff inside the camera requires a class of geeks that I imagine both the marketing and optical/mechanical engineering people at Leica dreaded having to deal with. Financial realities would most likely have required that Leica only hire a coordinating layer of people to write specifications and interface with contractors (at Sinar for the DMR and at Jenoptik and Phase One for the M) who really do the work. I imagine the low credibility usually granted to this kind of engineering interface work would not have helped to increase communication among the team of many new people that put the M8 together in less than two years, a short time for a product this complex.

Most of the teething troubles of the M8—streaks, freezeups, battery management uncertainties— have happened to all new models of digital appliances, and get solved in time without too much fuss. Two others are clear reflections of this culture shock. Even before the camera was fully released and posting raw files was permitted, those who could read the bootleg files available, or the spec which said that every raw DNG file would be exactly 10MB long, realized that something was wrong with the public statement that the M8 would offer "full 16-bit" resolution. It didn't take long to figure out that Kodak's 14-bit data was being transformed by a sort of simple gamma transform into 8 bits per pixel. This was confirmed eventually by an article in Leica Fotographie International, so Leica knew this, but the marketing statements were never corrected, even to say "16-bit range" instead of "16-bit resolution." My speculation is that someone in the "untouchable" firmware layer at Leica had tried for a while to explain this to the marketers, but couldn't get them to take the time to really understand the difference, when they were all so busy ensuring that Magnum photographers, fond reviewers, and music celebrities all had their beta M8s in time to make the right impression at Photokina. The trick turns out to be a good one. The M8 DNG files are extremely robust under post-processing, and the extra factor of 2 or more in processing speed, plus reduction of 2x in storage volume, is worthwhile.

The other, much more serious, "failure to communicate" was the lack of recognition on Leica's part that ignoring an extremely high IR sensitivity would cause problems for any customer working in color, and some in B&W as well. This issue was understood by the scanning digital back community (but none of those are left at Leica after the S-1's failure). Those have no IR filtration at the sensor. Excess IR sensitivity bit Kodak and Nikon fairly badly with several early DSLR models in the late 90s and early 2000s. But Leica, until after the camera had shipped, continued to believe that this problem affected only fashion shooters who might encounter synthetic fabrics. This problem, more than any other, incited hoots and howls of derision, instant web histories, and even coherent explanations of the effect, its causes, and the different directions for resolution. Leica, to its credit, admitted the problem within two weeks, and formally announced a solution in six weeks. They leaked it even sooner—"forget about a new sensor IR filter design as that would sink the product; it's filters, guys, but we will give you some and prepare a channel if you want more of them."

Beta testers and web solutions
The second place where Mike presents a common and off-base misimpression is his characterization of the webforum discussions of the Leica M8's issues as the work of anal ruler-shooters, who should better spend their time taking "real pictures." Yeah, it got pretty noisy, but with its first 1500 shipped units Leica obtained beta test feedback on the M8 that they didn't have time or manpower to do themselves. It was done fast (hardware problems nailed in two weeks, some surprising consequences of offset microlenses in one month), and Leica has been able to respond.

Trying to get simple, clear answers to complex questions from discussions on the web is possible only if you can learn to extract signal from a fair amount of noise. I've subscribed to the Leica-Camera-Users forum, which has hosted many critical but constructive threads, and which gives full credit to four or five main individuals (plus many others) for providing solutions that early users of the M8 could use and collecting/filtering bug reports. It has taken, typically, one or two weeks at most to get a clear sense of what are real problems and how they can be reliably made to occur. This is misunderstood by some, but once a problem is reproducible, an engineer can do something about it. The best of the forum discussions have uncovered two layers of problems so far, one already solved, a second claimed to be soluble in a coming firmware release. I hope that will be all the major issues, but who knows?

The real payoff is that the M8 takes fantastic pictures. In the right hands, with its 10MP Kodak sensor, 12–14 bit dynamic range, and no AA filter, its only competition is the Canon 5D, which with good lenses doesn't cost all that much less than the M8. That's my experience with my M8 after a month of shooting, and certainly the reason that it is selling well—order backlogs continue for both cameras and lenses.

Scott Kirpatrick spent almost 20 years of his life involved with product developers in various parts of IBM. That's the source of his speculations of the cultural issues involved in trying to engineer a complex product with mechanical, optical, and digital issues and market it effectively. He wrote up a "technical business case" on the M8 introduction, which you can see on his academic web page in PowerPoint or in .pdf.

Perhaps a comparison to Porsche would be more apt (although the Harley-Davidson comparison works for me because it takes into account both company's near demise). Since automobiles, and motorcycles, are at the most basic level, transportation devices, no one really needs a Porsche Turbo 911 to drive to work, or Leica M8 to produce amazing pictures. To purchase either commodity is an emotional nostalgic decision.

It seems that Leica believed that if the M8 was used in "real" picture-taking situations, the problems that the "anal ruler-shooters" pontificated about wouldn't be problems. I find it hard to believe that Leica would have released the camera if they did think it was problematic, in the real world, assuming they were aware of the "problems" in the first place.

This is an interesting review. The M8 seems to be quite a nice camera capable of producing great images. I feel that the comparison with the Canon 5D is a bit disingenuous, though.

You state that "its only competition is the Canon 5D, which with good lenses doesn't cost all that much less than the M8". The Leica M8 retails for $4800 (from B&H) for the body only. The Canon 5D currently retails for $2500. The difference could be spent on a 24 f/1.4L and 35 f/1.4L with enough left for a compact flash card or two. With the Leica you would still be facing another nearly $4000 to put a lens on it. They're hardly in the same ballpark.

Leica's engineers seem to be pretty swift. They knew about this camera's problems, and I'm sure that they were wont to fix them.

But Photokina was a hard deadline. If they needed to release by then, there must have been a business reason for it. All engineers eventually have to deal with the fact that their craft is more often directed by dollars than sense. You can't sit on a product forever, perfecting its every flaw -- or as Steve Jobs once said, "Real artists ship."

In response to the 5D argument -- a 5D with a 24-105mm f/4L is currently $3070 after (double) rebate.

It's also about 5 pounds, about eight inches long and about 4 inches in circumference.

The M8 isn't for everybody, but it does offer a great philosophical counter to the DSLR -- great quality that's as subdued as it is expensive. We need more of that in digital photography -- real innovations and paradigms shifts like the M8, the 5D or the SD-14 -- or we'll just end up with endless evolutionary revisions.

Scott's statement that Leica started selling a defective camera because they didn't have the time or manpower to fully test it doesn't speak very well for the company. I wonder how many of the first 1500 photographers that spent $5k for the body plus $$$ more for lenses understood that they were beta testers as Scott describes them?

I confess my comparison with the 5D was OPW (other people's wisdom -- mostly from Sean Reid). I have never owned Canon gear because of its bulk. I use and like an E-1 and will probably upgrade when they finally put out a weatherproof 10+ MP version. And the work Carl Weese publishes on his site with his Pentax K10D and its small prime lenses makes a good case for that system.

A couple of perspectives that I see:

First, speaking as an engineer having been responsible for interfaces in major projects (billions of dollars):
1. Dealine driven projects always fall short on quality. If the PMA date was hard for Leica, that was a mistake.
2.Project Managers tend to under-estimate the importance and time of things new or outside their expertise area. For Leica, the firmware & electronic bits are big departures, I wonder if this happened on the M8.

Second, as a consumer. I drive anj expensive German car, I paid premium for it. A big reason I feel it was worth the extra is the attention to detail. There are also a lot of little, uquantifiable (but tangible) details that make it stand above the competition.
For the M8, IMO, to be worth the extra it would have to show that same attention to the minutiae. It doesn't, as far as I can see. While I am very much impressed by the image quality and understand the benefits of its handling, there are too many little details over-looked to justify the price. A a much lower price, these could be overlooked as "teething troubles".

If the issues were so quickly identified and fixed, why wasn't this done pre-release. A flawed product is forever devalued.

Hi, the Leica S1 story at the Met has not just vanished! There is a fantastic New Yorker article that relates this amazing story involving the first digital Leica and the Chudnovsky brothers, two mathematical geniuses involved later on the projet to stitch the 200 CDs of shots into a massive digital patchwork.
The article is still available on line:

Btw, thanks for this blog, Mike

Thank you for this post most well thought out explanation I have read on the M8 roll out ..

Well, the M8 may not cost any more than a canon 5D with good lenses but, if i'm not mistaken, an M8 with the lenses to do it justice is another matter altogether...

Thanks for the comments: One thing I would like to add, is a thank you to Leica for getting the M8 to market in the first place. It is a very risky (though necessary) phase for a small company. Without their efforts, we would not have a 'real' M to use in the fully digital world. I hope it works, I hope it sells, I hope there is a little tolerance: We need variety, and Canon are so dominant that we may end up without it.

A digital M8 "with the lenses to do it justice" is a matter on which opinions differ widely. New Leica lenses come in a price space all their own, several thousand dollars, Euros or what have you, apiece. New Zeiss M-lenses of outstanding quality sell for about $1000 apiece, and are preferred by some to the Leica equivalents. Cosina-built Voigtlaender lenses are quite competitive (and sometimes much smaller) for this application, and sell for $300-500 each. Sean Reid at , a subscription site that is well worth the small charge, is working his way systematically through all of these options and has posted comparison images.

And those of us who love the older lenses (and have inherited or preserved some) post comments and reactions on the Leice-Camera-Unsers forum under titles such as "Great Old Performers." There's nothing like the glow of an old Leica lens, even though "glow" is really a euphemism for "flare."

While M lenses certainly add to the price of an M8 (comparing against the Canon D5), my guess is that buyers of the M8 will be old Leica users who already have a collection of M lenses. And, the question is "Do I want a digital rangefinder body with which I can use my M lenses?" For me, the answer is "Yes". My M8 is on order and due next week. I can't wait to take it out for a spin. My 28 Summicron is already on its way to Leica for 6 bit encoding and others will follow.
