I'm wanting to set my first custom setting and make it suitable for bird/wildlife photography in good light. I found an article on AP somewhere (haven't been able to find it since) which I think recommended going with ISO 400 and setting aperture at one or two stops back from maximum setting to get "the lens sweet spot". With this advice in mind I did a backyard test on a sunny day with ISO 400, aperture priority with aperture set at 6.3 (only realised later that 6.3 is in fact the maximum aperture at 500mm for this lens) and lens at 500mm focal length. I have to admit to shooting through a UV filter (Sigma) just because having it on makes me feel that my expensive lens glass has some protection over it (yes I have read the post from the NO UV FILter side). Below is the result
I used a monopod and shutter speed came in at 1/800. Any tips from the experts out here? Would coming back a stop on the aperture be a good idea?
Question 2 relates to a general setting for action photography in good light at longer focal lengths. Do I need a seperate custom setting (say shuter priority) or will the bird one do the trick? A couple of days later I tried the same settings while watching the 18 footers on a cloudy day. This picture is at about 300mm focal length (still ISO 400, aperture 6.3) and shutter speed came in at 1/2500. Hand held with OS on 2
At the risk of displaying m ignorance ....
The shutter speed seems good for the action shot but why was the shutter so much faster than the magpie picture when this was a cloudy day?
Why was the bird picture only 2.4MB as compared to 3.4MB for the sailing one?
