I just received the Canon T4i and Sigma 100-300 f/4. Right out of the box I find the AF on the Sigma extremely fast and the zoom/focus rings very smooth. For being over 3 pounds the lens is very well balanced and solid. The Canon's controls are easy to use and I've taken a few pictures so far. All shots were handheld and taken in Manual. I've been keeping the shutter speed at 1/1000 or higher to eliminate shake. For birds in trees and brush I've been using the center AF point, and for BIF I've used auto focus points. The images were shot in large JPEG format, (Not quite sure about how to process RAW yet) and are crops of the original. I set the ISO to a max of 1600- thoughts? AF mode is set to Al Focus- is Al Servo suitable for perched birds as well as well as moving birds?
I have attached a couple of my first (and best) photos so far. EXIF information is below. Both pictures have been resized to the maximum size that BirdForum will upload. I will post more photos for critique when I have time.
In the photo of the Robin I noticed very strange bokeh, with grainy horizontal lines. I do have a UV filter on for protection- is this the cause of it? I have seen great photos taken with this lens, so I'm unsure what the cause of it is. Thoughts on both?
Northern Harrier- 1/1250 f/5.6 ISO 320
Robin- 1/1250 f/5.6 ISO 400
Thanks
