I was given the Pentax QS-1 body for Christmas. I took it out today as Partner in Climb is on nights and I needed to be out of the house for a while to let her sleep. In my abstract winter wandering I came upon a robin.
I was using one of the old Pentax 110 lenses – the 70mm telephoto (with crop factor on the QS-1: 330mm). Manual focus might be a bit tricky on impatient wildlife but it let me get a level of detail that was pretty extraordinary. All of these pictures are shot on the 70mm. Click to embiggen.
