Nothing too exotic today (though do look at the video clip at the end). I was playing around with my EF 400mm f/5.6L USM prime lens between rain showers. It’s a good lens but in the past I’ve had difficulty consistently achieving sharp shots with it. That’s partly because it lacks image stabilization, but I’ve also suspected it needed calibrating (which is possible on the 7D). A few test shots seemed to indicate it was focusing short (i.e slightly in front of the image). I tested various settings (trial and error) and found a 10 point adjustment seemed to do the trick. The camera retains the settings on a lens-by-lens basis, so I should now be able to forget about it and get on with the business of taking photos. See what you think 😉
First a couple of photos of one of the ubiquitous garden woodpigeons.
Now for a the equally common jackdaws.
My favourite sequence though was a magpie. A pair were flying back and forth between the gardens for most of the afternoon (their nest is about six gardens away).
All in all I’m reasonably pleased with the results. The lack of stabilization does mean I need to work harder to get the shots, and I certainly need decent light to keep the shutter speed high. The adjustment does seem to have helped and I achieved a better ratio of keepers than usual. What I would really like though is this (unlikely to happen any time soon).
Now for the video clip. It’s a female badger showing signs of lactating. 😀
