If, like me, you bought one of the smallest Digital SLRs from Olympus, such as the E-400, E-410, or E-420, but couldn’t bring yourself to pay nearly £160 for the Olympus 25mm Pancake lens then you might be interested in this alternative. Pictured here is an ultra small Industar 50mm Russian M42 mount lens (50-2, 50mm, f3.5), on an M42 / OM (4/3) adapter. M42 lenses are widely available from ebay, and are excellent value for money if you don’t mind manual focus and aperture settings. Click here to view more pictures.
The Industar 50-2 m42 lens measures just 21mm, compared to the Olympus 25mm lens’s 23.5mm, although with the m42 to OM 4/3 adapter it measures 29mm combined. You can view the Industar 50-2 in it’s natural habitat on a Zenit SLR here.
