Lens Adapter fit or lens quality puzzle
Sep 8, 2012

I've got two issues:

1) a lens adapter that may or may not be affecting sharpness.

2) legacy lenses that were quite sharp on film but seem only par with the kit lens--leaving me either disappointed with the legacy lenses or really impressed by the kit lens.

The lens adapter is a FOTODIOX PK-m4/3. Adapter to body (E-PL1) is tight but adapter to legacy lens is loose: almost a millimeter rotationally and a tiny bit of side to side shift (but not rocking).

Shooting using the timer, mounted on a tripod, IBIS off I'm getting no better sharpness from my legacy lenses than I am from the kit lens (and possibly not quite as good as the kit lens).

M.Zuiko Digital 14-42mm (1st gen)
Pentax SMC-FA 35mm f/2 AL
Pentax SMC-FA 100mm f/2.8 macro

So, any thoughts? Is my slightly loose adapter making my favorite legacy lenses look weak or is the kit lens really that good?
