With me and the 5D Mark III’s full-frame sensor it’s all a crap shoot, but I’m learning by going where I have to go. For the time being, depth of field is the challenge.
Lens: Canon EF 24-105mm f/4L.
1st shot: lens at 105mm, 1/250 second at f/4.5, ISO 100.
2nd shot: lens at 58mm, 1/1600 second at f/4.5, ISO 500.
