How to set your camera for bird photography, or at least some ideas.
First thing to say is there is no right or wrong way,the camera needs setting to suit you and your situation,my preferred choice is manual with auto ISO on the D7200.
My reasons are as follows
1 I want to control the shutter choice
2 I want to control the aperture choice
3 This leaves only one thing that can be varied in the hope I can attain the choices I want in the first two.
The usable top ISO will vary between camera models and what your prepared to put up with in the way of noise,with the D7200 for me its a max of 6400 ISO,i would rather not go that high but I will to get me out and taking pictures.
Focus point settings its single for me though I know others have great success with one of the multi point settings,I have tried them but when viewed in NX-i set to show focus point I found I can do better than the camera at keeping the focus point where I want it.
I dont lock the single focus point so I can move it with the command dial to the part of the bird I want,normally the head and a press of the OK button returns it to the center,see BBF bellow as an alternative.
BBF or Back Button Focus,this setting is very popular,it separates the focus and taking action, plus it gives focus lock and continues focus on one button /setting, depending on if you keep it depressed or not.
I dont use it at the moment as when I had the D7100 it over rode my focus priority setting,i have been told it doesn’t do this with the D7200 so I need to try it again.
The over riding benefit as far as I can see is when using BBF no matter how much you re-frame the focus point will not change, unless you press the button again.
U1 and U2 these two settings I use for exposure compensation I have U2 set for +1 and U1 set for +2 ev,I have poor eyesight as far as reading is concerned so found I can use these settings via the Braille system
,without looking at anything turning the mode dial to the right from M gives me one click I dont want two clicks +1 three clicks +2.
As for metering well I have gone back to my roots for the moment and trying center weighted,spot can be the most accurate but you need a thorough understanding of what its doing,matrix will just work well in loads of situations but not always perfectly.
