Hello;
I recently registered on your site but have enjoyed the tests/reviews and the overall site in general for quite a while. I own a Fuji X-E! and several lenses - one of them being the Fujinon XF 18-55mm f/2.8-4 R LM OIS lens.
I followed your instructions on how to test for decentering etc. Opened the lens to maximum aperture, used a tripod, manual focus etc. and enlarged the image in Live View. The inner-most edges were uniform when in and out of focus, (so that's good, right?) After that is when I got confused.
You stated "if you want to do it correctly - do it with a tripod and taske a picture with Live View AF". Would I then expect the resulting image to be sharp? When I performed the test with Live View AF and viewed it on the screen at 100%, I saw what appeared to be some artifacts and CA on the edges.
It certainly looked better to me when manually focusing and enlarging the image under magnification using Live View on the LCD prior to taking the picture.
Am I missing something?
Thanks
Brad
