"Nighttime Force Shot?"


Valparaiso, US
          

Last night I went out in pitch blackness with an ancient Nikkor 50mm F1.4 mounted on my D50. I set everything to manual, fired a test with the SB600, and adjusted the aperture until it was 'pretty good' exposure. I picked the hyperfocal distance according to the resulting f-stop. Life is good while gleefully shooting my grandson sledding down the hill.

Tonight, the battery for my new D7k finished charging just 30 minutes ago. I've spent the last half hour trying to force the same shot with the kit lens and SB600. It just refuses to fire.

I've looked at the manual, but can't find any way to FORCE it to make an exposure, any exposure at all, even if it is wrong....
What am I missing?

Note, the D7k/SB600 exposes wonderfully when given just a moderate amout of ambient illumination to focus and 'figure out' the rest of the exposure. Absolutely perfect test shots to prove it works.

Set it in manual focus mode - almost certainly it cannot detect AF lock, so it doesn't release the shutter.

You may also want to shoot in manual exposure mode, as you had to with the D50 - as your "ancient" 50/f1.4 is probably a manual focus version.

Hi Mike,

Do you have your MF 50mm f/1.4 entered into the cameras non-CPU lens data in the camera menu? See page 159 and 160 in the Nikon D7000 Users Manual .
Good Luck and Enjoy your Nikons!

Best Regards,
Marty

i haven't had this experience with the d7000, but i have had it with other nikon DSLRs. when things get really dark, it seems the camera cannot find enough contrast to get a focus lock on a moving target. this used to happen to me when shooting a night ski jumping event at the lake placid olympic venue. the solution was to set everything manual ... focus and exposure. i would select the spot where i hoped to catch the skier going by over me and manually focus the lens for that spot. i'd also do test frames until i had the lighting down. then, when i could hear the skier coming down the ramp (couldn't see him in the dark), i'd point the camera to the selected spot and just hold down the shutter release until the skier had gone past. this normally produced usable frames. like you, i was using an older-tech lens ... my 85mm f1.4. since this involved multiple frames shot rapidly, i did not use the flash

Thanks! Oh... You mean I'm supposed to take that user manual out of the cellophane wrap? Seriously, I spent most of the battery charging time lacing up the neck strap. Getting a little old here and the snow is knee deep in the back yard. Wouldn't want to drop the outfit.
I will try both approaches. Yes, the ancient 50mm is a 1960's total manual, came with my first FTn.
I will need to research mounting it and the rest of the old glass AFTER I retire my concern about damage to the D7k. I've been warned that there may be a mechanical conflict and would not want to tear up a good body.
BTW ~ this morning there were three deer out on the ice by the dock, and the SB600 reached out quite well over the 55-300mm VRII.
I appreciate all your advice.
Merry Christmas to all!

Can we see your "red eyed" deer?

I went out in the dark last night and took some shots of our Christmas in the Country Pageant with my 35mm f/1.8 DX.

I had mixed result with onboard flash and using none on my D7000.
I could barely see thru the viewfinder so I started using the LCD in LiveView.
This made things worst until I turned up the EV.
I then found out in review, that each step + introduced more noise.
I turn it back close to 0 and got an acceptable Video of a skit and some singing.
Of course I did not have an external mic handy so part of the singing was ruined by my voice.

RRRoger ~ I hesitate to do this... Not my best work.
But anyone who connects EV, noise and singing can't be all bad.

And I thought Rudolph"s nose was bright!

I bet these deer can see in the dark.

Thanks

same problem a simple workaround is to use a small flashlight on
the subject to help the camera figure things out. I use a little
led flashlight to shine enough light for the brains of the camera to
figure things out and the camera will shoot and with the flash illumination it dosn't show
