Nostalgia isn't what it used to be, but that hasn't stopped several photographic manufacturers bringing various 'retro' models to the table that look as if they've been brought back from a bygone age.

On most of these, the vintage styling has been largely cosmetic, and inside they boast all the latest features. That said, the latest camera to join this old-school clan goes one step further, by combining digital capture with a classic rangefinder design. It's the R-D1.

What's most surprising about this new retro camera is the company behind this initiative. You might have expected it to come from Leica, a manufacturer with enormous pedigree in this area, or even a longestablished brand such as Rollei. But no. The R-D1 comes from Epson, a company which, although enormously successful when it comes to printers, has yet to get a serious foothold in the camera market.

The rangefinder design has been around since the 1920s and, although technology has come a long way over that period, it still has a loyal following, particularly among photographers who favour a lightweight, unobtrusive, go-anywhere camera.

But not everything about the past was great. This is particularly true when it comes to exposure. Most modern digital cameras feature some kind of multi-zone metering system that takes readings from several parts of the scene and integrates them to maximise accuracy. Like many traditional cameras, the R-D1 only features a centre-weighted metering system - and it shows.

Hit and miss

Most of the pictures we took with the R-D1 required some tweaking on the exposure front, and a handful were so wide of the mark that it was impossible to salvage them. Virtually every picture taken towards the light was severely underexposed, and any scene with large areas of brightness caused moderate underexposure.

Those with sufficient knowledge and experience will know how to overcome this limitation - by tipping the camera down and using the exposure lock button with landscapes, or giving up to two stops more using the exposure compensation system. This system, by the way, is straight out of the 1970s and involves lifting and turning part of the dial on the top of the camera. It's a similarly cumbersome process when you have to change the ISO setting.

The same dial also selects your shutter speed, and the R-D1's only automatic mode, aperture-priority. In this mode, you select the aperture using the ring at the front of the lens, and the camera sets the corresponding shutter speed. There are large gaps between the stop settings on the lens, making 1/2 or even 1/4 stop adjustments possible.

It's the focusing system, though, that really defines a rangefinder camera. And here we're talking about 'manual' focusing. To render your subject in focus, rotate the barrel of the lens until the two images you can see in the viewfinder coincide. Although the R-D1 captures images digitally, there's no 'live' image on the LCD - you can only use it to review the pictures you've taken.

Not everyone takes to rangefinder focusing. Most find it fussy and slow compared to autofocus, though the more you use it the easier it becomes. There's also a danger in fast changing situations that you forget to focus, and don't realise your mistake until after the event, when it's too late.

While it's cute having a digital camera with rangefinder focusing, you might wonder what's the point, when even with candids and 'street' photography - areas where rangefinders established their reputation - auto-focus now does it more quickly and more accurately.
