I think the Oly 17 1.8 is a bit underrated. It's a beautiful little lens physically (a totally different animal to the relatively cheap looking 45 and 25), and although not in the same league as the pro line lenses for IQ perhaps, still very good indeed, focuses quickly, has nice bokeh and is sharp corner to corner. I'm surprised how often I look at an old photo that I really like and find in the EXIF that I took it with the 17 f1.8. Perhaps the reason they haven't updated it is that they can't make it significantly better than it already is.

Well, the "problem" is that it is not sharp corner to corner when the centre is in focus because of the field curvature. One of the reasons why it has a good Bokeh.

Does this matter to you? It depends on why you bought the lens.

For landscapes, there are better lenses but the17 f1.8 was designed for street photography where the field curvature works well.

Check out the link where Roger measures and discusses this.

The 45 f1.8 is similar in this regard.

This is one of the reasons why a lot of people prefer the PL15mm f1.7
