Today the sky was mostly cloudy and it was rather nippy outside. A lot of birds came to our bird feeder. At one time, as I walked by the patio door, I saw three bright red Northern Cardinals perched on the magnolia tree, waiting for their turn. I got my camera out and started shooting, first with the 1.4 extender attached to the lens.
Two hours later, they were still flying in and out. This time I did not use the 1.4 extender.
I prefer the shots taken without the 1.4 extender as they are noticeably sharper, which will come in handy with large-size prints for framing. However, the ones with the extender are really not too bad.
