Don't feel bad. Sadly I just haven't been using this lens much. I've been staying busy with the 100-400mm since birds are coming through again. Here are a few odds and ends just to make you feel better.
I otherwise stay away from shooting the 50mm at f1.4 in the broad daylight but this time, I wanted to capture the unintentionally groomed trail that will give hikers a headache when they try to trek it in subfreezing temperatures.
Couldn't resist adding a few of my own - Since getting this lens, I've noticed my focus is off slightly at f1.4-1.8, but moving to AFServo appears to be sorting the issue - I'm just not used to such shallow DOF ! I'm generally pleased with the colours and ease of use, just be a bit odd not having zoom !
