This is a set of 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. The tubes fit all the classic models from the OM1 to OM4 series, OM10 to OM40 and OM2000, with OM manual focus lenses. They can also be adapted to fit many digital SLRs and mirrorless cameras with suitable adapters (not included) using manual OM lenses only. The tubes are in very good condition, supplied with metal front/rear caps and a copy of an instruction leaflet. Please read the full description for more important information.

Three tubes are supplied (12mm, 19mm and 26mm) and all can be used singly or together in any combination for up to 57mm extension – the longer the extension used, the closer you'll get. With a 50mm standard lens, the full set will get you to slightly greater than 1:1 (actually 1.14x life size). This is better than most dedicated macro lenses, filling the frame with a subject as small as 21.1x31.6mm (0.9x1.3") on film and even smaller on most digital cameras, and is ideal for photographing many small objects such as coins, stamps, insects, etc. Greater magnification is available with moderate wide angle lenses, while 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 independent Kenlock tubes are very solidly made (in Japan), with metal barrels and lens mounts, ribbed grips and in a glossy black finish with chrome fittings. They are up to around 60mm (2.4") in diameter and weigh approximately 210g (7.4oz).

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

Condition: Excellent+++ (8.5/10)
The tubes are in fully working order, fit and lock securely with all couplings working correctly. They have a smooth finish and clean paintwork, and there is only the usual evidence that they've been used, including some surface marks and minor paint wear here and there – mainly around the grips and bayonet mounts. The caps are in good condition and fit OK, while the instructions are a generic copy but complete (in English) and legible.

No dents, dings or deep scratches, and overall they're in nice shape.
