Here's something for the big cat lovers - a photo of a young tiger carrying his lunch. It was a great day with wonderful light and I had my 400mm with me, but almost all of the shots didn't meet my standards because I had to shoot through really bad glass and they all look as if they were taken with a $100 1000mm astro-lens . Finding a park having big cats AND good photography conditions is a big problem for me so far... so I'll have to stick to wolves
I eventually ended up using the 70-200 for this shot, the glass had less negative effect on that lens.
Nürnberger Zoo is great. They have the nicest place I have ever seen for the tigers and it's really convenient for us photographers to get good shots Just in case you're in the area ...
