The bestseller by Kahneman about the slow and fast systems of decision-making does clearly show that human beings may believe that they are acting rational, but the chance that this is the case is rather low. The larger body dimensions refer to the total thickness including the monitor, selection wheel and thumb rest.

It erwwin a strange quirk of history that current reviewers of digital cameras give so much attention to an issue that makes them in fact film emulsion testers and not camera testers. It is not an innovative product in the sense of an iPod or iPad. We do not know, but two facts are undeniable. The photography market is no different.

Erwin Puts Book – The Leica Compendium –

But do we need innovation in an industry that has hardly changed since ? And the third no longer hidden assumption is the idea that a failed photograph is no longer the fault ldica the operator but of the camera and the software that are not up-to-date or up-to-the-task. Despite a heavy price tag, all three editions sold out quickly. The ccompendium that accompany the claim are indeed not good. When the Nikon F5 was announced at one of such meetings, one person dared to ask when the F6 would arrive!

The main question for the future is: The M3 in its day was a camera that incorporated as many features as possible within the optical-mechanical technology of its day.


Technically highly interesting, but for the final image not that relevant. Basically the M6J was a fine mix of the M3 outside and the M6 inside.

In the usual reviews of cameras and software programs there is always a listing of likes and dislikes where the dislikes is often an enumeration of lacking features that the presumed competition offers. Therefore companies try to reduce cost by re-using as many components as possible.

I can say without hesitation that the digital files produced by the M8 are better than any DSLR on the market by quite a margin. The basic thinking behind the feature is the adapted Zone system for digital photographers as originally explained by the previous Kodak workers of X-tol fame Silvia Zawadzki and Dick Dickerson. These are products constructed with the engineering approach: That is photographically relevant.

Lenses could be evaluated on a range of criteria like sharpness and contrast over the image area, at different apertures and at different distances. This choice was deliberate: A 30x45mm sensor does not imply better quality than an APS-C sized sensor. The theory of evolution states that the cause of a major change is a new constellation of the environment leading to the loss of no-longer-functional elements. If a spring or a screw was needed, the compendiu manager knew luts to assess the component and immediately saw the potential problems, if any!

Recently I spoke to a frwin editor who runs every product through the test cycle of Imatest. In the past this was indeed the case: I have not made any tests yet, but I have a hunch that rangefinder focusing with such a fine rangefinder might actually be more accurate than current autofocus systems, particularly with wide angle lenses.

The results obtainable with the lenses were based on the optical performance. I don’t know the Lens Compendium. If we add the the production of cine-lenses to the comendium, it is difficult to escape the notion that this is a collage of companies that may have the potential to share fundamental product components and development insights, a potential that for now is still quite limited.


Leica Compendium by Erwin Puts. The fact that these characteristics were the logical consequence of an aberration correction that would define these lenses as the best in the world was simply immaterial.

It is therefore a bit unsettling to read that the management of Leica is contemplating to shorten its product cycles and to introduce more new products to keep pace with the competition. Looking at the announcements made during this half year we may wonder where the big Japanese companies are heading to.

Digital cameras changed all this and killed in fact that basic intrinsic experience of film-based photography. Buying material goods, like cars or iphones or cameras, is not a rational activity and certainly not based on a rational or logical reasoning.

Many magazines and many websites like DP-review and DxO-labs thrive on the belief that comparative evaluations and numerical listings do influence the buying decision and buyers do assume that they make a decision based on the analysis of facts.

The pictures lfica taken with a mm lens. The alignment of the sensor, the adjustment of the rangefinder show now a level of precision that was impossible to achieve in the past unless a very experienced worker did the job, when allowing this person all the time s he needed.
