Ever since I bought my Sigma 70-300 f/4, I haven't been able to change the aperture when using it. Last night, I tore into the lens and made modifications that allow me to set the aperture manually (that's another post on it's own). So, I dragged my brother and sister to a local park so I could see if it worked. What do you think? All but the first image are with that lens. Please critique/comment! #1 - "Breaking the rules" (taken with my Canon 18-55 kit lens) #2 - "Hey, it didn't come back down" (Sigma) #3 - "Karen" (Sigma) #4 - "Roadkill" (Sigma) #5 - "Hello" (Sigma) Please let me know what you think. Good bad or ugly.
