Well, I broke down and placed an order on the new Sigma 30mm f/1.4 DC DN Contemporary with B&H earlier this week and it arrived yesterday evening. What can I say, the allure of an f/1.4 native, full-mode autofocusing, APS-C E-mount lens was too much to resist... and getting a refund on taxes helped. So here's some of my first few photos, including a bunch from my first ever semi-serious attempt at testing using a chart (I need to amp up my lighting though).

DSC07845 by SRHawk64, on Flickr Test Chart at 5.6. DSC07847 by SRHawk64, on Flickr And, finally, Test Chart at f/8. Note: These are not the full-size versions here. But you can click through to Flickr to see those if you'd like. I need to work on my test setup and procedure, particularly getting more lighting into my living room "studio". But I did try my best to ensure the chart on the wall was level to the vertical and horizontal and line up the camera with all four corners of the 3:2 area of the chart as best as possible. There could be some slight misalignment. And I began to think last night (and have been wondering about it since I got the a6000) that either my a6000 itself or the lens(es) need some AF micro adjustment... I suspect some front focusing.
