Olympus Zuiko Digital 25mm 1:2.8 'pancake' Gordon Laing, June 2008

More Results : Outdoor / Resolution / Corner sharpness / Fringe and macro / Geometry / Vignetting

Olympus ZD 25mm corner sharpness

  To compare corner sharpness we photographed the Enhanced Digital Camera Resolution Chart with a variety of Four Thirds lenses, including the 25mm pancake, the 50mm macro and the latest Olympus kit zoom at its widest and longest focal length.

Each lens was tested with various apertures using Aperture Priority mode. The crops are taken from the lower left corner of the chart and presented here at 100%.

The Olympus 25mm lens exhibits a little coloured fringing in the extreme corners throughout its aperture range - this is apparent in all three samples below, although in the first with the aperture wide open at f2.8, the vignetting is masking some of the effect. Judging from our other tests, this fringing appears to be the biggest optical issue with the 25mm pancake lens, and it's a shame you can't completely eliminate it by stopping-down the aperture. To see how it impacts a real-life situation, see our first outdoor results page. Otherwise, let's continue with the results on our fringing and macro page.
