    Hi All,

    I just posted a (very) amateur review of the Olympus 25mm f1.8. It's the first review I've ever done, so I hope to get more in depth as time allows. I posted a bunch of lens test photos and bokeh comparisons, as I thought those of you on the fence might find them useful.

    I always enjoy reading reviews by actual users. Thank you.

    I commend your for shooting a resolution chart. I suggest when shooting that chart, set the exposure compensation to +0.7. It is primarily white and throws off a camera's meter. Exposure for digital is not quite as critical as it was for film, but it's still important. How big was the chart that you used? I wound up breaking it up over multiple sheets so I could shoot it from a couple of meters away with a normal lens.

    That's good to know, I thought they were too dark but didn't want to make adjustments afterwards. The chart was small, only 8x10, because that's the only high quality paper I had around. Next time, probably with the Olympus 45mm, it'll be bigger.

    Are there any tricks to getting things totally square, or just lots of trial and error?

    Thanks for the kind words everyone!

    I decided to split my photos into two Flickr groups, one with edited photos and one for my blog, so my "good" photo stream didn't get overrun by bokeh comparisons and resolution charts. The good one is at http://flickr.com/ryansommers

    For best results the proper exposure has to be used. Under exposure introduces noise that will obscure fine detail and over exposure will lose fine detail. Roger Cicala's post Setting Up an Optical Testing Station has some tips for lining things up.
