Contax 159MM This camera was my first Contax and still my favourite. the 159 is a solid performer with programme shooting, a useful 1/4000th top shutter speed and TTL flash metering at 1/250th. The size is perfectly balanced with the 50/1.4 or any of the f/2.8 primes up to the 135mm Sonnar.
Contax Aria A great ‘modern’ companion to my 159MM, the Aria has pretty much all of the mod-cons including motor wind, spot and matrix metering, auto bracketing etc. It feels much more refined than the 167MT which preceded it. I would say it also has a better finder with easier to read information compared with my 159MM. It could be the best film camera I have owned, it’s certainly very much up there with my Canon T90.
Contax 139 Quartz A nice little camera and the predecessor to may favoured 159MM similar sized but lacking the fast flash sync and programme modes. I owned one for a bit as it came with a lens I wanted. But sold it on in favour of the 159.
Contax RTS III A beast of a camera it’s a bit intimidating and heavy to carry around although the flatness of film plane due to the vacuum pressure plate means it’s likely the best camera for extracting maximum performance from the Contax lenses. Eventually swapped it for my Aria.
