D610 Back Button Focus
Oct 17, 2014 07:53:38 #
I have set my AE-L AF-L to AF ON. I noticed that in Single Servo if I press the back button, remove my finger from the button, then recompose the shot and then shoot, the photo when zoomed in all the way is not as focused as if I had shot without recomposing. Is this normal or is there some other setting I need to set in the menu? I did not have this problem on my 600 but not sure if I have all the menu settings correct now.

I've seen articles about focusing at different focal lengths. I think that's the issue, rather than BBF. Try the same thing using manual focus.

Explain "recomposing" - did you change the zoom, aperture?

I am surprised you did not have that problem with the D600 because varying the focal length from a short focal lenght to tele will surely defocus the image.
A simple remedy is to focus at the end of the zoom range and then recompose using the focal lenght that you want to use. The picture will be in perfect focus.

Handy tip... never new that, but tested and it seems right on....

No changing the lens itself, just moving the camera to the left or right, up or down. I was using my 28-300mm, shooting around 65mm. Maybe its the sensitivity of that lens.

Could it have been an exposure change? Manual mode or auto exposure?

One of the problems with "recomposing" is that some times you inadvertently change the distance from camera to subject. I am sure you had the same problem with your other camera but just did not notice it.

That is what I was thinking... be helpful to know the focus point locks before and after recomposing....

There is a way in LR to see the focus point on the image. I posted it a couple of weeks ago, but I seem to have lost it.

I believe to see your focus point in Lightroom you need to install a plugin, the plugin is free and can be found here:

It works on most Canon and Nikons, it does work on Nikon D600/610 and the D300s, but just make sure your camera is on the list.

I never under stood the advantage of viewing the focus point on an image. Sure, you can view the focus point that was chosen but not necessarily the area that it was focused on.
When handholding a camera I almost always use the single center focus point so if I focus then "recompose" my focus point is no longer on the area that I focused on.

One thing that it allows is showing you where the camera focused so you can compare it to where you thought you focused, it could reveal a problem with your cameras AF, but people find it very helpful when using continuing focus mode, it can reveal how your camera thinks and tracks moving objects

I think the idea is that if your image isn't in focus, that add-on will show you where the camera was focusing. Also, if you zoom in to sharpen the image, the focus point will show you the best area to sharpen.
