This is a set of independent auto extension tubes which fit between your SLR camera and lens for extra close focusing (macro) shots, up to 1:1 (life size) or even better. They retain all the automatic features of your lens and camera combination on Olympus OM manual focus 35mm film SLR cameras and lenses (see below). They can also be adapted to fit many digital SLRs and compact system cameras with suitable adapters and manual OM lenses (adapters not included – see the Compatibility section below). They're in fully working order, good condition, supplied with caps and a copy of the instructions. Please read the full description for more important information.

Three tubes are supplied (12mm, 20mm and 36mm) and all can be used singly or together in any combination for up to 68mm extension – the longer the extension used, the closer you'll get. With a 50mm standard lens, the full set will get you to greater than 1:1 (actually over 1.3x life size). This is better than most dedicated macro lenses, filling the frame with a subject as small as 18x26mm (0.8x1.2 inches) on film and even smaller on most digital cameras, and is ideal for photographing many small objects such as coins, stamps, insects, etc. Even greater magnification is available with wider angle lenses. Longer lenses offer lower magnification, but more comfortable working distances.

The tubes retain the fully automatic diaphragm and full aperture metering of the OM manual focus camera and lens combination (where appropriate), so are fast and easy to use, with no extra manual procedures required. Compatible with all manual and auto exposure modes, including program where available. TTL metering systems (including TTL flash) will take care of the required exposure correction automatically. These generic (unbranded) tubes are very solidly made (in Japan) with metal barrels and lens mounts, weighing around 260g (9.1oz).

An essential close up accessory for Olympus OM manual focus film users.

Condition: Excellent++ (8/10)
The tubes are in fully working order, fit and lock securely with all couplings working correctly. They have a smooth finish, clean paintwork and only the usual evidence that they've been used, including some surface scratches, scrapes and minor paint wear here and there. The box is showing signs of age, the caps are in good condition but fit a little loosely, while the instructions are a generic copy but legible.

No dents, dings or deep scratches, and overall they're in good shape.
Boxed with generic instructions, front and rear caps. Pictures in this listing show the actual tubes offered for sale.
