INSERT IMAGE FROM WEB: Copy image address (right click) and past here Cooper's Hawk (d500 with 200-500)

Like you, I have 1 (Dx) D500 and 1 (Fx) DF I would make the lenses more interchangeable focal length on the two bodies 35mm f1.8 equivalent as 52.50mm on d500 16-35 mm f 4 equivalent as 24-52.5mm ...

... and no hot shoe cover (manual checked )

If you want to lock exposure after press AF On to focus, then press AE_L before recompose

Yes VR on handheld and 15 fps continuos

And here is my try 200-500 mm on V2 (no tc2 this time yet)

Speechless!. Thank you for sharing. I will try what I have: V2-TC2-and 200-500

Thank you everyone. I will call off the deal of D4

For the same price of D500, a D4 with 5000 clicks is a good choice for BIF or the D500 is better option?. I need the feature of 10fps (Both), D500 153 focus point and highlight priority vs 51pts, ...

Nice photo. Just curious, what is the black spot on her dress by her foot?

I don't have d500 yet, but with my d800 i go to image area to shoot 1.2, 1.5 or 4/5. I suspect you can do the same 1.3 for d500 (I read it somewhere)

And in-camera 1.3x = 390-975mm (?)

I just finished editing wedding shoots. Final culling result of 175/1200. Df with 35 1.8g 80%, the remain 20% D800 with other lenses 24-70, 70-200, 85 1.8g here is a sample of indoor venue photo

wow! very impressive. What lens were you using? 300 f4?

Thank you for your detail analyzing. I appreciated your valued input!

you are correct. but do you think that was thin dof of this far distance and f 5.6?

Thank you everyone for input/advise. I know a lot to learn a head for BIF and using long lens

My first photo BIF with long tele (heavy crop and process with LR)

he come at the right time, but wrong place (something in background stick out his head)
