On my off days I sometimes go to the nearby creek to take pictures of these water fowl that are usually chill about getting their picture taken. Stills are nice, but I wanted to use my 7D to it's full potential for getting action shots of them flying or taking off. I have a Canon 75-300mm USM III f4.0-5.6 that I got dirt cheap to play with.
My issue is that 95% of the time I'm taking pictures I'm at 300mm, so I started thinking I needed to look into a lens to use more of the focal range. Instead of just impulse buy something and hope for the best, I wanted to ask for some suggestions on what would be a good lens/teleconverter option to go with a Canon crop sensor.
My original idea was to grab a 1.4x teleconverter and upgrade to the newer Tamron 70-300mm at a later point, as this current Canon telephoto really shows why it's so cheap. My white storks are turning purple.
