I put in a pre-order for the new Sigma 16mm F1.4 prime for Sony E-mount...it's supposed to start shipping Nov 22, assuming no delays, so I hope to have it for Pixelmania. It will be nice to finally have something wider and fast for dark rides and walkaround - up to now, my widest has been 30mm F1.4, which on APS-C is still pretty tight. The 16mm will be a nice standard wide 24mm equivalent, and Sigma's latest batches of lenses have been quite sharp and good...so hopefully this one will too! For $449 it seemed a very reasonable price.
