I assigned FX/DX switch to the L-Fn2 button(s) on my new 600PF. Kinda like a built-in TC. 
(Now I have to remember it’s there.) Is this a good use?

If you would like to post, you'll need to register. Note that if you have a BCG store account, you'll need a new, separate account here (we keep the two sites separate for security purposes).
Whatever works best for your ergonomics; I have DX mode set to the "Disp" button on my Z8.
I did that exact thing! However, I can't recall using itI assigned FX/DX switch to the L-Fn2 button(s) on my new 600PF. Kinda like a built-in TC.

I don't use or currently have a need for any of the lens buttons on my 800PF with my Z9. That could be different if I had a Z8 and lost an FN button. I like all my front buttons as toggles, I assign my FN buttons as follows
FN1-RSF (Hold)
FN2-Slient
FN3 FX/DX Switch.
My rear buttons for all my AF Area+AF ON modes.
Shutter - Auto Area AF mode
AF-ON - 3D as backup to Auto Area though use it less then 5% of the time.
Sub Selector - Single Point
But I think most don't get why to use DX mode or when. It's not for "cropping" or to get more "reach", it's to enlarge the subject in the EVF as the AF system works directly off the EVF. Been saying this for 2 years now with the Z9. You can see the AF grab the head at a certain distance in FX but hit DX and it instantly grabs the eye. Hit FX and it instantly goes back to the AF box on the head. You can clearly see the difference. I'd much rather have a tack sharp 19.2MP image then a soft 45MP image.

Fn 2 on my Z8 and Fn 3 on the Z9 are programed FX and DX.

Whatever works for you. I do not use any on the buttons on my lenses not do I assign any function to the ring on the lens
