10-20mm
January 30th, 2010
I bought a second-hand 10-20mm Sigma lens the other weekend, and last Tuesday I got my first real opportunity to use it while visiting a friend who was dog-sitting a friend’s dog for a few weeks. We got outside to walk the dog, and I took some pictures of Leiden as we went along. It still amazes me how much red and yellow light ordinary lampposts give out. Humans apparently compensate for it, but on my EOS400D, the sensor picks it up mercilessly. There’s a lot of Photoshop going into making night photography around Leiden look good!
Looking at the pictures I took, I now realize it takes a lot to get to know a particular lens. I need to get to know this lens a lot. That’s cool, because it means taking lots of pictures with it 
. The first thing I noticed is that the fish-eye effect is much bigger than I anticipated. You can see this effect best around the edges of the first picture. It doesn’t show up as much in the second picture, but that is mostly because there are no vertical lines in it. The second is that Depth-Of-Field is weird in these picutres; I need to get used to the fact that around the edges, objects might be quite close!
The rest of this post has pictures of Goji, the dog my friend was dog-sitting. I took lots of pictures of it, but those of you that own a dog or any other pet know it is difficult to get action pictures where the object is actually sharp; animals keep moving! Nonetheless, I managed to get a few good pictures of this wonderfully happy dog!
