IntroductionThe 28-70mm range is considered by many professional photographers to be the most widely used one on a 35mm film or sensor. Therefore it is not a big surprise that most manufacturers offer lenses in this range for the professionals as well as for the beginners. Third party companies are not an exception to this rule.
Angenieux is a French firm well known for their high quality motion camera lenses as well as for some important innovations in the optics. In the 1990-ies it tried to enter the photography marked by offering some very interesting lenses for the main camera body manufacturers: Nikon and Canon. Unfortunately they did not see a future for their efforts and discontinued the production line focusing on motion camera lenses only.
The AF Angenieux 28-70mm f/2.6 was one of the most anticipated Angenieux products but only some 3000 F-mount lenses were produced. I was told that Nikon delivered the electronics for these lenses, so no reverse engineering was necessary on the Angenieux side. However I was not able to find any confirmation to this online.
Noticeably, the lens has a constant opening aperture at f/2.6 but this is not registered by the two Nikons I tested it on which showed f/2.8 instead.
Even today, using digital equipment, some customers continue to report superb image quality delivered by the Angenieux 28-70mm and some consider it even better than the Nikon flagship lens in this range: Nikkor AF-S 28-70mm f/2.8D ("The Beast"). This was the reason I decided to buy an Angenieux and am fortunate to have a very well preserved one now.
Soon after I started taking pictures with the lens, I noticed that it delivers somewhat "softy" pictures. I decided to buy The Beast and do this test.

For some years now we have a multiseat system based on Ubuntu (since it was initially very easy to set on). Moving to a new apartment made us think about how to place the furniture and most important the working desk (with the two workstations) as well as the speaker boxes. Until now the (Class A, SET vacuum tube) amplifier and the (also vacuum tube) DAC were on the desk with the speaker boxes placed on the two sides of the working table.
However, in the new apartment we decided to place the working desk in a corner. This brought up the question where to place the speakers. We decided to put them on a remote wall of the room. The problem was now how to control the sound from the common machine (client).

Yesterday I saw "You Will Meet a Tall Dark Stranger" by Woody Allen and had to discuss two things with my wife:
1. Woody Allen uses always the same font for the credits in his movies.
2. In his recent movies he started presenting more a segment of a story than the whole one.

The reports and pictures about the situation in Japan dominated the media in the last week surpassing even the (possible) genocide in Libya. We were able to see horrible pictures of devastation as well as to witness the dignity the Japanese people are facing the tragedy with. Still, to me the most stunning aspect of the situation is something else.

The lead article in the last "The Economist" is about China's economy. While you read it, you might ask yourself if there are any original ideas by the Chinese Communist Party that sustained. We all know that the development of the (meanwhile second largest) world economy is done by exploiting workers. Paradoxically this is what communists used to recruit supporters in the past... worldwide.

Electronic devices for reading long text files (e.g. eBooks) have become very fashionable in the last couple of years. One could wonder what changed for this to happen. After all flat screens have been around for some decades now. Portable flat screens also!
Tablet laptops (yes, they were called with the word "tablet") were produced at least for a decade now. With the introduction of the iPad, the tablets ran quickly into the consumers’ daily life. Charismatic as always, Steve Jobs presented the iPad about a year ago. The presentation was quite interesting because we know that Apple was hesitant whether to get into the market with Netbooks where Asus was making meanwhile a lot of profit with its Eee. Eventually they decided to offer something without a real keyboard in the same price range. Steve explained how you could listen to music (!) and see pictures (!!) on this new device. Incredible, those novelties! :)

The ubiquitous use of WordPress nowadays makes it mandatory for consideration when one starts a new blog. And there are good reasons to choose WP among all the alternatives: it is open-sourced(!); it has the largest community, so support is not an issue; the zillions of plugins and themes allow making almost everything out of it; Matt Mullenweg (founding developer of WordPress) is a nice guy and has one of the coolest domains for his website: ma.tt :)...
