In Topic: Back Button focus/Nikon D7100

HI Leah, it sounds like you have skipped one step in the process to setup BBF.  When you are pushing the shutter button, that is when the focus goes in and out?  To use the back button focus properly you want to turn off the ability of the shutter button to focus.  That way, you use the back button to focus to the point you want and you can then pull the shutter button at any time after that and the focus won't be affected.  Basically if something moves you can rock back and forth to bring things back into focus without having to focus again.  This is a godsend when shooting macro


I have the D7000 and the D7200 and they are a little different, one extra step with the D7200, I am not exactly sure with the D7100.


With the D7000 should be this:


Turn on your AF-C

Then go to Menu -> Custom Settings (the Pencil) ->Autofocus - AF-C and set it to Release

Then go to Menu -> Custom Settings (the Pencil) -> Controls -> Assign AE-L/AF-L Button ->AF-On


Then test your Shutter button, it should then no longer control Autofocus.


With the D7200

Same as above, however, also need to do  Custom Settings -> Autofocus -> AF Activation - AF-On Only

This last step turns off the Shutter button AF on the D7200


Key thing you need to figure out though is:  when you push the shutter button half way, is it doing Autofocus?  If so, then your back button focus won't work properly so one of the steps above needs to be done to allow it to work properly


Hope that makes sense

Great info, one last thing to remember is to "save user settings" for your custom assignments.


Menu->Setup menu (wrench)-> Save user settings-> OK -> save to U1 (or U2)-> OK -> Save settings

"The limitations on using any "on board" slave sensor is that it will typically have to be in line of sight with the triggering strobe."   

Understood, while testing around the house I put it in obstructed areas and found that it fired but of course it was getting light bounce off walls etc. that's not gonna happen UW.  Going to take it along to Bonaire next week and give it a try. Will report back.

I have also wanted to try some remote slave lighting. I pulled out an old Nikonos 105 (brand new sort of since they were replaceing them for free) fired up with fresh batteries and am amazed at how optically sensitive it is in slave mode. This is through air and with diffusser on, fireing at 25' easily with 105 at 90deg from camera flash.  Anyone used the 105 for this? Limitations UW?
