Continuing the high ISO theme. K-1 for these.

Was out at the weekend and shot these. All were shot in TAV mode, with shutter speed reduced to as slow as I was comfortable with to get the shots. And all shot wide open with te DFA 150-450 to allow in maximum light. The blue tit and the nuthatch are about 1/4 of the frame. To me the blue tit is completely acceptable. While detail is starting to be lost on the nuthatch. Some nice bokeh too.

The bittern was shot in crop mode (as I find it improves AF performance). This was then slightly cropped. Acceptable, only when you need to get the shot
