This being a very cold January to date and a non-competitve birding year (for a change) we have not done a huge amount other than count garden birds these past ten days since the new year … which has given me the opportunity to do a little experiment.
My bird photographs are usually taken with a big lens attached to very big DSLR camera body but I also have a DSLR-quality mirrorless camera which is amazingly small and light. I also have adapters that allow me to use Canon lenses on this (Sony) body but thus far have only used this feature for wide angle and walk-around photography but I wondered how it would take to the big bird-glass? The pictures below were all taken through the window which degrades the quality somewhat, but for all that it’s as good as the main Canon camera can achieve … could be a life saver in terms weight when travelling (airlines hate too much weight in your carry-ons) and especially when hiking; worth pursuing anyway.
So these pictures were taken with a Canon 300mm lens plus a 1.4x extender attached to a Sony NEX-7 body via a Metabones EF-E mount adapter. Most were manually focused using the focus-peaking setting as it is faster with this combination than is autofocus. All hand-held – ISO set at 400 with speed and aperture selected by the camera.
