Testing 1....2

Our Catalpa tree is in full bloom now... the bees are loving it.  We had a little rain and wind today as some of the flowers were knocked off.  I'm testing my designed for small sensor cameras wide angle lens here.  It's a 11-16mm (third party) for a small sensor camera but seems to work just fine at 16mm on my full frame camera at the least on the wide setting.  This was taken set at 14mm so the vignette starts to show up.   Set at 16mm the problem is gone.   For unknown reasons Canons own small sensor designed lenses wont hook up to a full frame Canon.....must be a board room decision and certainly not an engineering one.
