jk wrote:Graham, Eric, Don't quite understand the need to focus at the edge of the frame? With a bird in flight I find I need to keep it dead centre or I run the risk of clipping a wing. I have single spot focus as default on the back AF (thumb) button with Group and Wide area assigned to the front function button and dof preview button respectively, which I can use as required instead of the thumb for more challenging subjects. Not sure what I am missing? But would welcome everyone's thoughts.

If the focus points don't cover the whole screen then it wont acquire focus until you are within the area covered by the focus points. The ability to have the bird in centre of the screen is very desirable but not always but you want the camera to try to acquire as soon as object starts to appear in viewfinder.

I am not doubting the principal but I've never found that a problem. I am old school and still feel I am quicker moving the camera to the subject rather than moving focus points around the screen. (Anyway I always forget to move them back afterwards!) So it's second nature for me to centre the bird. But I am planning to photograph Hobby's catching butterflies this Summer....so I may hang onto the D500 till then.

I put the D500 on Dynamic Area AF-C 153 points, and then it will capture lock as bird(s) enter the viewfinder and the AF lock is achieved before it is in the central section. I cant do the same on the D850 which only has Dynamic Area in the central section. I have just been looking at the D850 manual. They have a section called Subject Tracking AF (see page 43). This seems to provide similar functionality to the D500 as it says "Position the focus point over your subject and press the center of the multi selector. The focus point will track the selected subject as it moves through the frame. To end press center of the multi selector again." I find that this works well for me.

Horses for courses, and with big objects like horses I find the tight central cluster of focus points on the 610 ideal, the last thing I want is the camera deciding to focus on the rail behind the horse! When photographing the DC3s I found auto focus a waste of time - it just would not stay locked on, I think I would find bird photography challenging!

I never had a problem with the mere 51 focus points of the D3 and I don't anticipate any with the D4 but I do have to get used to the idea that the native ISO is only 100. I was wondering why I couldn't get it to track a dog on Monday, nothing to do with AF, lots to do with a shutter speed of 1/15s

Ive started to test JKs assertions and today been 'chasing' seagulls over the garden. In addition to giving myself neck and upper arm muscle cramps I have discovered that while tracking, keeping the bird in frame with focus locked on....you have to remember to fire the shutter.

How does the dynamic area mode choose to focus on the bird flying at the edge of the frame if there is a tree or other object in the middle of the frame? I will have a look at the Subject Tracking option on Friday.....got visitors tomorrow.

I dont know but it worked for me when I first got my D500 and 200-500. I was trying to capture African BeeEaters which fly very fast and high. But when they swoop down you can get some very nice shots. I havent had a chance to test extensively as they are only in my area in Spain for about one week in April/May and again in September. I will start to use again after this winter when I hopefully I have more free time. At present I am trying to get a dry day so I can go and check my chimney stack and its flashings. Also need to clean the gulleys around it as I am getting some damp penetration around it. Oh the joys of Grade II Listed buildings!

I pretty much had the AF sorted for birds with the D3 but the D4 is subtly different so I need some more practice, and better light. Following Kites can be interesting because they tend to travel in circles that drift with the wind. Try panning as they go directly overhead and you run a serious risk of falling over! Today isn't a day to experiment, it is raining and there aren't any kites about.
