Braun made collecting their camera tedious.  They didn't bother putting model names on their cameras.  OK, this says "Paxette" but that is a range of cameras not a specific Braun camera.  My other Braun camera also says 'Paxette' and they are clearly different models.

The basic body of the design is the same but this current model has no extinction meter (no great loss) but does have a rangefinder (no great gain) and an exchangeable lens.

The film advance is a lever advance but it really is just a lever stuck on a knob winder.  It requires two full strokes to advance the film one frame - a bit awkward and not really any better than a simple knob would be.  I suspect the main advantage of adding the lever was a marketing one rather than a practical one.  The second travel of the film advance cocks the shutter and reduces the film counter by one (this camera counts down from the length of the film to zero).

Film rewind is still a knob and I prefer this to the small cranks that became popular through the 1960-s, 70s and 80s.  If a maker fits a rewind crank then it should be a sizeable one as on a Zeiss Ikon Contessa LKE. 

This camera does not have the extinction meter that my other Paxette has.  In its place is an uncoupled rangefinder.  This is adjusted by a small vertical wheel which works well enough but is a bit on the small side for my fingers.  As the rangefinder is uncoupled it is necessary to read the distance from a small window by the adjustment wheel and then transfer this reading to the focussing ring on the lens.  Guessing the distance is easier with a bit of practice and just as accurate with the lens stopped down to f8 or so.  The rangefinder and focus ring are both marked in meters which is unusual in an official import from Germany - the back of the camera is clearly marked "Made in Germany" so it is an official import.  My other Paxette has the focus ring marked in feet, so it is not a case of Braun not having the resources to produce market dependant versions.

The shutter is a Prontor SVS which was very much the standard shutter with serious cameras at this time. (1953 or so).  Compur shutters have something of a better name but I have never had a Prontor shutter of fifty or sixty years age be anything but excellent.

Shutter speeds seem to be about right.  I have no way of testing them but the manufacturers were happy with +/- 20% of the marked speed.  Half a stop out is not a problem  - half a stop is when the 1/300 speed is actually 1/225 or 1/450 seconds.  Your negative will be well exposed with that much error.

The shutter also has a PC (for Prontor Compur) flash connector with M or X flash synchronisation and V (V= Vorlaufwerk) for delayed exposure settings.  It is general wisdom not to try the V setting on old cameras as this can fail and prevent the shutter working at all.  Sure enough, when I tried 'V' it failed.  It took a bit of coaxing to get the shutter to fire.  In fact, I had to manually move the shutter blades (something else you should never do) while depressing the shutter release.  Not recommended and in future I shall heed accepted wisdom and leave the 'V' setting alone.

The iris diaphragm has (I think) twelve blades giving what is very close to a circular aperture - good for those concerned with bokeh.  The lens itself is a Cassarit 45 mm lens with a maximum aperture of f2.8  The Cassarit lens has three elements.  I can see no evidence of any coating (usually visible as a blueish sheen) but coatings were normal by 1953 and I suspect the lens has at least some coating.

The shutter release is the same as on my other Paxette - a bit of a hair trigger - but is rendered safer by being stationed between two of the stanchions which hold the shutter housing in place on the front of the camera.

Camera with back/base removed

Loading the camera is simple.  You release the back by turning the wheel around the tripod boss on the base (it takes quite a few turns).  The back and base come off as one piece making access to then inside easy.  There is a hinged bracket which must be moved to one side to put the new cassette in place - one the bracket is returned to its place, the cassette is held securely.  The pressure plate is attached to the camera body, not the back, and this must be raise to put the film between the guide rails (see picture).  If you forget, your film will not be exposed!  The leader of the film goes into a slot on the take-up spool - there is nothing to hold the film in place but it works well enough.

There is an accessory shoe on the top plate (cold shoe in flash terms) in front of which is the frame counter.  The frame counter is set by a toothed wheel behind the accessory shoe.  You need to set this to the length of the film when loading a new roll as the counter counts down to zero at the end of the film.

Rewinding the film is quite awkward.  With your right hand you have to press a small button on the top plate while with your left hand you need to partially raise the rewind knob and then turn it to wind the film into the cassette.  With such a small camera it is difficult to do this two handed.  I found the rewind knob kept putting itself back in the rest position - in this position, the knob will rotate freely and the film is not rewound.  Also, it was not clear when the film had been rewound so I found it necessary to keep winding long after I thought the film must be rewound in case I opened the back and fogged a length of exposed film.  Normally, there is a significant resistance from the film when rewinding and when the film leaves the take-up spool, this resistance is significantly reduced.  With the Paxette IIM, the awkwardness of rewinding masks this change in resistance.

I now have some sample pictures available from this camera.  These were taken on Agfa Vista+ negative film (made by Fuji, if you are interested).  They show up the susceptibility of this lens for flare and there is significant vignetting in the first picture but once you avoid light sources, the lens is quite sharp and gives good contrast.

Braun Paxette

My latest purchase is a Braun Paxette.  I am not entirely sure of the model - it seems to be a variant on the Paxette I - it has a Roeschlein-Kreuznach lens and a lever film winder.  This camera is fairly heavy for its size (that it to say, solid!).  It measures 11.5 cm wide by 6 cm high and 6 cm deep.  The Braun that made this camera is Braun of Nurnberg - there being at least one other Braun company making cameras.  I also have a different Braun Paxette model, the Paxette IIM - details here.

While this camera is not quite of the quality of the Voigtlander Vito B, it is a well made camera and was far from cheap when new.  Wallace Heaton (a photographic retailer) was advertising this in 1952 at £24/10/6 (in old money. That equates to £24.52 in new money and is equivalent to around £1,500 at 2013 values).

Braun Paxette
lens: Pointar
focal length:  45mm
apertures: f2.8 to f16
focus range: 3 feet to infinity
lens fitting: fixed
shutter: Prontor SVS
speeds: 1,1/2, 1/5, 1/10, 1/25, 1/50, 1/100, 1/300
flash: PC socket, X and M
film size: 35mm

The back is removed by unscrewing a ring around the tripod boss on the base.  The back, base and half the front then come away as one piece.   The new film cassette is held securely by a swivelling arm which makes this camera much easier to load than the Zeiss Ikon Contaflex cameras which also have the base and back come away in one piece but have nothing to hold the new cassette until the loading is finished and the back/base replaced.  In my camera, the new film is held beneath a plate that must be hinged out of the way before the film is loaded.  This plate then acts as the pressure plate that keeps the film flat - there are a couple of springs in the back that keep this plate snug against the film.  In other Paxette models, there is only a small clip to secure the film while loading.

The shutter is a Gauthier Prontor SVS which offers the usual speeds - 1,1/2, 1/5, 1/10, 1/25, 1/50, 1/100, 1/300 and B - as well as M and X flash synchronisation and V (vorlaufwerk = delay) and has a PC flash connector.  The shutter release is on the side of the shutter housing.  As this shutter is cocked by winding the film, it is very easy to take photographs by mistake.  In use, it is going to be necessary to wind the film on just before taking the next picture.

The lens is a Pointar lens made by Roeschlein- Kreuznach.  This is a 45 mm lens and is coated (at least, the lens bezel has a red "C" on it which I assume means it is coated).  Roeschlein were a small lens designer and manufacturer in Kreuznach set up in the 1940s and sold to Sill Optics in 1962.  Their lenses were mostly designed to order but they made several lenses for the Paxette range of cameras.  This lens does not seem to have a very good reputation but I will judge for myself when I see the results of my test film.

Film advance is by way of a short lever which needs to be turned full travel twice to fully advance the film.  In earlier versions of the Paxette, film advance was with a knob only and I suspect this has merely had a lever attached rather than being redesigned as a lever advance.   The film rewind is a knob on the left side of the top plate.  This needs to be pulled up fully to engage the rewind mechanism.  In the rest position, it is not connected to anything which I originally mistook to mean the film was not attached properly as the rewind knob does not turn as the film is advanced.

The extinction meter is simplicity itself to use.  You look through the right-hand window at a series of numbers.  The faintest number you can see indicates the required exposure - this number is looked up on a chart on the rear of the leather every-ready case to get the aperture/speed combination required.  Downsides:  you need to look at the numbers for a long time (20 seconds is suggested in the manual) to allow your eye to adjust to the available light and you need to have the case with you at all times to access the chart.  This actually works quite well.  I have been comparing the exposure suggested by the extinction meter with the reading from my Zeiss Ikon Ikophot meter and they pretty much agree.

The frame counter is in a slightly sunken recess in the top plate and counts down to zero, so needs to be set with the length of the film loaded.  This recess also doubles as an accessory shoe - a cold shoe in flash terms.

This camera is not the easiest to use. The viewfinder is too small to use while wearing my glasses and the shutter release has a hair trigger. Those are my main complaints in using the camera. To hold, it is very much like the Voigtlander Vito B - the same size, weight and basic shape. I suspect the Braun designers had a Vito B in mind when they were designing the Paxette I. Apart from squinting through the viewfinder, I enjoyed using this camera although I don't think I will bother with the extinction meter again. It is so much easier and quicker to use my Ikophot or Leningrad handheld meters. Loading film while out and about is easy enough - the hardest part is finding somewhere to put the removed back/base while fiddling with the film.

Some sample pictures from this camera.  These were taken with a colour film that was several years past its best before date and had not been stored properly - hence the colour cast and colour noise.  Also, I exposed according to the built-in extinction meter and they were all rather under exposed.  With old film it is usual to give a stop or so extra exposure but this film got to be under exposed.
