I've always been quite happy with my zoom lenses but lately, I don't know if it's user-error or what, but I'm getting quite noticeable distortion when using the 14-42mm mark II kit lens, and also sometimes with the 14-140mm. However, when I use the 20mm prime, it's perfectly aligned. So, I'm going to persevere with the 20mm for a few months (early new year resolution) to see what I can do as I can now see such a difference. If I get on with a prime I may even invest in some other focal lengths for specific subjects.

Hi Chris, I've noticed a bit of distortion at times from my 14-42 but not much and more so from my two zooms.

I looked it up from somewhere on the net and discovered that the effect was due to using the electronic shutter.

I turned the electronic shutter off and there wasn't much of a difference with the 14-42 although the two zooms no longer have such big distortion when shooting scenes with horizontal or parallel lines in them.

I did a test with a 45-150 and a 45-200 with the electronic shutter on and off and distortion becomes minimal with it off.

Well that's interesting. I can't really understand why the viewing mechanism can make a difference to distortion but I'll give it a try. Cheers. Smile
