1minute, I used to be worried about low light with it but I look now at using my cameras at ISO 3200 or 6400 if needed and the noise is minimal. I can deal with it especially when I look at the savings as you mentioned.
pal, The bokeh doesn't really bother me much. The Iceland Gull image was at about 260mm, so it doesn't smooth out really like it would at 600mm. Plus I was shooting at f8 to go for a little more depth of field. This gull is pretty rare around these parts and I wanted to make sure I captured all the detail.
