Error message on my D70....

[Mad Dave]

Hi guys,

whilst shooting some 10sec exposures in Barcelona last week, my D70, upon completing the exposure, displayed the message 'File NR' and failed to show the image on the LCD as normal. If I left it a good 30 seconds it would then show it up, but usually I just switched the camera off and back on - it then displayed the image fine. I shot a couple of normal 1/60th shots later with a different CF card and it behaved fine, and when I put the original back in, it was then fine too. Very odd. I'm thinking it may be a CF card problem but i'm a bit concerned as work may be sending me to Ukraine at the end of the month on a photography assignment so it's imperative I have a functioning D70!!

Also thinking of using this as a (pretty valid, really) excuse to buy a D200 and use the D70 as a backup

Buy a Canon my friend

I use a D70 every now and then and it's not the most reliable pall . . . but then, some are very satisfied. Take a new card to be sure. Format again, change battery etc. that type of thing works for me . . .

Odds-on a duff CF card. It will probably continue to work intermittently for a while, then give up the ghost completely. I'd get a new one and either bin the duff one or keep it as an emergency backup.

Early cards can be buggers . . . true. A 3 year old card only had half the shoot on . . . saying nothing when shooting :saved by a good start:

Eh . . . sounds like you have long exposure noise reduction enabled, and the camera is working correctly . . .

The camera takes two exposures, one with the shutter open and one with it closed (to calculate dark sensor noise) then subtracts the two images and stores the final one.

So if you take a 30 second exposure with NR enabled and the camera will spend 30 seconds after the shutter closes (whilst displaying Job NR) taking a second 30 second exposure . . .

You can switch this off via a menu option if you must . . .

I'd suggest formatting the cards now as switching the camera off when it's working on something (and may have started writing to the card) could cause problems.

DOH!!!!

You're completely right - the night before I got bored and started flitting through the menus, and I enabled this feature!

I feel like such an idiot!!!

Thanks for all the help guys, i'll format the cards anyway though.

Cheers

Dave
