'Malaysia Photography Blog - A quick outing with the manual focus Olympus F.Zuiko Auto-S 38mm F1.8 legacy lens mounted on the Olympus E-P5'

The E.Zuiko Auto-T 100mm F3.5, another lens from the series produced for the Olympus Pen F/FT Half-frame Camera System of the 1960's, is as an outstanding lens as portrayed on a series of web pages including an image series by kuuan on Flickr, a discussion of MFlenses, a showcase thread on Mu-43.com, and a discussion thread on Fuji-X forum.

My well-used and slightly battered copy of the E.Zuiko Auto-T 100mm F3.5 is, however, far from perfect. It has a thin layer of fungal infection across one of its inner elements, and although the aperture ring is soft and smooth, the focusing ring is rather stiff.

This makes using the lens on my Olympus Pen E-P5 a two-handed operation, making things rather slow and slightly awkward. Images too, unsharp with slightly low contrast, were not at their best.

A good copy of the lens, with clean and clear glass, and smooth rings will probably do you wonders.

At 100mm focal length, the lens will be the equivalent of a 200mm lens on the 2x crop-sensor Olympus E-P5, long enough to put the lens into the medium telephoto category, good for closed sports or action shorts. Bright ambient light should give you the shutter speed you need, recommended at 1/200 second minimum, to shoot with the lens handheld.

An advantage you have with these cute and compact Olympus Pen F/FT lenses is the need of a lens adapter which is very shallow. On the E-P5, the whole extension, including the lens hood is only 115mm long.

Note: Images were post-processed (and enhanced) on Olympus Viewer 3 (OV3) and print sharpened on Google NIK Sharpener Pro 3.
