A gap in the camera market?

It ought to be possible to produce a camera with a much reduced specification that will do most of the things the Leica M9 will do at a fraction of the price. It would incorporate a bright optical viewfinder like that on the M, but with a simple fixed projected frame. The sensor would be between 20mm and 25mm square and somewhere around 12 to 15 megapixels - no more. The lens would be fixed and wide-angle, with an equivalent focal length of about 30mm and an aperture of f/2.8 or f/2. If practicable, the sensor would be concave, to reduce aberration and provide a light path where all light rays struck the surface at 90 degrees, thereby avoiding the need for microlenses and simplifying the lens design.

The square format would be novel. Amongst other advantages, this format would permit the viewfinder to be used equally well with the left or right eye. It would also avoid having to make the decision whether to frame for a vertical or landscape format, as well as making the best possible use of the image produced by the lens.

For the sake of robustness, it would have manual focussing and the lens would have a thread for a protective filter. With such a small focal length, it will not be necessary to fit a rangefinder, although that could be optional.

The cost should be no more than £2000. How about it, someone?

Importing people to sustain demand

I got involved in a discussion with a Youtuber called “Philosophy all along”. This was in connection with criticism of Trump’s policy of deporting illegal migrants, which he argued would be bad for the economy as it would reduce demand. This implies that there is a need to import people to sustain demand. There is no obvious reason why a population should not be able to consume everything that the same population produces. If it can not, then something else is going on. It is a basic principle that wages are the least that workers will accept to do a job. Wages are a share of the value added by workers through their wages. The remainder is distributed as economic rent, after government has taken its cut in taxes. Monopoly profit is a temporary surplus that after a delay gets absorbed into economic rent. Land values in Silicon Valley are an example of this; it's like a gold rush. The miners get little out of it. Rent and tax syphon purchasing power away from those who produce the g...

The Zombie Train that refuses to die

The Guardian has published a couple more articles against HS2, one by specialist rail commentator Christian Wolmar, and another today by journalist Simon Jenkins. The main arguments in favour will doubtless be wheeled out by the commentators: the need for capacity and the disruption caused by upgrading existing routes. HST itself will severely disrupt services to Euston during the construction period. Capacity can be increased at a fraction of the cost by a variety of measures, provided that it is accepted that the additional traffic will run at existing speeds. It is not generally known that the Midland main line is, or was, four track all the way from London to Trent Junction, between Nottingham and Derby. This is because the additional tracks are separate, having been added for coal trains which trundled down to Brent sidings, on the edge of London, from a collection point at Toton in Nottinghamshire, where the Midland Railway build a huge marshalling yard. Beyond Derby, the main l...

How much more will the British tolerate?

The British are phlegmatic, tolerant and slow to rouse. Thus there was no great reaction after the terrorist attack in July 2005. The murder of Lee Rigby created a sense of outrage, but nothing more, since it appeared to be an isolated incident. Two serious incidents within a fortnight are another matter. Since the first major terrorist incident in 2001, authority has tried to persuade the public that Islam is a religion of peace, that these were isolated events, or the actions of deranged "lone wolves", having nothing to do with Islam, or to reassure that the chances of being killed in a terrorist attack were infinitesimally small. These assurances are are beginning to wear thin. They no longer convince. If government does not act effectively, people will take the law into their own hands. What, however, would effective action look like? What sort of effective action would not amount to rough justice for a lot of innocent people? Given the difficulties of keeping large n...
