Well, after a lot of online and off-line shopping for a sub-18mm lens, a deal finally came to me. CameraWorld lowered the price on the Tamron SP 14mm f/2.8 into my budget. I had looked at this lens before and been impressed, though I wish it were lighter; for the price I paid I can manage the weight. My first tests show a touch of back focus when up close in low light, so I need to watch out for that - and the extreme field of view can catch flares off the sun at surprising angles. In any case, it's very well put together and will capture some unique views.
