Diana De Luxe or Porst Happy

The Diana De Luxe is often considered a variant of the Diana, but it is in fact a completely different camera.

The first Diana
camera (without F for flash) is a simple plastic camera, often called toy camera, from the 1960s. It has no flash connection and was sold in a small yellow box, size of the camera. It was produced by the Great Wall Plastic Co. in Hong Kong and was branded with many names for different markets. The first model has "NO. 151 MADE IN HONG KONG" written on the lever releasing the back. The Dianas were either sold at prices as low as $1 or given away as promotional items. They were packed in boxes of 144 cameras for the resellers. The original Dianas used 120 film.

The lens is simple plastic meniscus lens with some vignetting. Light leaks are frequent, often you had to put black tape over the seams. Each frame is 42mm x 42mm, so a roll of 120 film gives 16 frames. Focusing is done by turning the lens' index to 3 zones, 4-6ft, 6-12ft, or 12ft to infinity. There are 3 F-stops, sometimes said to be random, around F4.5, F8 and F11 due to less sensitive film in the 1960s and smaller towards the end of production (F11, F13 and F19). Several variations in top-plate and lens-barrel style appeared.

The second model had a flash, hence its name "Diana F". It was sold in a bigger red box which also contained the bulb flash.
It is marked "NO. 162 MADE IN HONG KONG" on the lever releasing the back. By the end of the 1970s 120 film was replaced by 135 film in cheap cameras. It is not sure when the production of the original Diana stopped, but full cases of 144 Dianas were still available in the 2000s. 135 film versions or look-alikes appeared in the 1970s.

The Diana De Luxe has a number of significant differences. It exposes full 66 cm images, 12 per roll of 120 film. As the 44 image of the original Diana showed already some vignetting at the corners, they chose a curved film plane to reduce vignetting and aberration of the simple plastic lens. The De Luxe has a shutter release at the top of the camera. It has an ordinary hot shoe. Most name variants have a fake piece of plastic at the front which resembles a selenium meter. The lens is labeled Plasicion, it has 3 working F-stops and the distane setting is done via a ring on the lens barrel. It has also 2 spring sheets of metal for film tensioning to avoid "fat rolls", a feature that even the Diana F+ is missing. And even the film wind is on the other side.

The Diana De Luxe was sold under several names, as: Dana 120 Flash, Porst Happy, Photon 120 Camera, Colorflash De Luxe and Elflex De Luxe.

Some say, the Diana De Luxe dates from the 50s or early 60s. I don't believe this. According to a Hong Kong industrial history site, the Great Wall company was founded in 1955 and began making the original Diana version during the 1960s. The De Luxe is a complete re-design. Hot shoes only became common in the late 60s. The design of the camera resembles a late 60s or early 70s design, like the Agfa Silette LK Sensor from 1970. The silver plastic is not painted, it's solid. So no moulds of the original Diana were used. The mould number is not indicated on my camera, but sometimes
"NO. 155 MADE IN HONG KONG" is indicated on the box. Nobody knows why the better De Luxe model did not survive the Diana F.

For the Porst Happy some websites even give a year, 1953. I think this is completely wrong. The warranty papers of my camera ask a stamp of 0.20 DM to be glued. This fee applies since 1974. So my camera is from 1974 or later. And no, Porst did not keep those models for many years, they bought an important number at once and sold them off.

In.2007 the 
Lomographische AG in Vienna launched the Diana F+ in the original 120 format. The medium-format Diana F+ is has become a system camera, with interchangeable lenses, electronic flashes and film backs. It has two formats, the original 16 frame 42x42mm, and a 12-frames-per-film 52x52mm. Features such as a tripod socket and a shutter lock were added.

The Diana De Luxe  isn't a reasonable camera nowadays, even if it's better than the F. It is a basic plastic camera with only one speed, no automatic exposure, no automatic film advance, no autofocus, not even a rangefinder, a simply made plastic lens and random results.
If you want to get into the Dianas, you better get a Diana F+, which offers a whole system and can be affordable second hand. But as I love to play with old basic stuff, the Diana De Luxe is a nice find for me.

As there is no "B" setting, there is a trick: Get the cap in your hand, turn the camera upside down and press the shutter. It will open, but not close, as the it closes by gravity. Push the cap on at the end of exposure and turn the camera back to normal position. Action the shutter twice with the cap on to ensure normal workig. Done. Don't forget to advance the film.
