I finally had time on a sunny day to test out my new 9-18mm with the E5 around the village. Subjects chosen to take advantage of the DoF and fill-in flash from the FL50R used with the memorials in the shade of the yews.

I must admit that I am a little concerned with the apparent lack of sharpness and slightly subdued colours (as viewed in the Raw file) together with more than expected CA. But hey it's early days yet! Any comments would be helpful. All jpegs ppd in PSE9

Great set, David, you've made a cracking start with the new lens. I must say that none of the problems you mention are apparent in these edited files. I've always regarded my 9-18mm as a great performer and haven't noticed any problems. What aperture was you shooting at? :)

Did you try focusing manually? they do seem a tad out. I have had no problems with sharpnes when I use my 9-18.

These were all shot @9mm @f11. I did some tests indoors at various apertures and fond no perceptable difference between f5.6 and f11 regarding diffraction softening. However at full aperture there was a little softening which disappeared at higher values. I have still to do some proper focus tests to see if I need to use the AF adjust facility. But as I said it's early days yet.

A nice set of shots, if perhaps just a tad soft as Yorky says. A problem with wide-angle lenses is selecting the point upon which to focus. I always find it best to focus quite close and let the distant points look after themselves. Also, I'd be inclined not to stop down beyond f8.

I have now done a series of comparison tests with other lenses set at the same focal length of 14mm with the same exposure and focus parameters and if anything the 9-18mm is at least as sharp if not sharper than some. Unfortunately I wasn't able to use another lens that was as wide as 9mm. I don't know quite what happened with my first shots but I'm happy now!
