hI all, whilst out shooting today on the Lukemia Rally my D300 started acting strangely,I was shooting in Jpeg in manual mode, I found that the shutter speed was changing on its own going from anywhere between 1/80 to 1/1250 can anybody shed some light on this please.
 
Is your ISO set to auto?
 
Have you got exposure bracketing switched on? a +/- 2 stop bracket would take you from 1/80th to around 1/1250th.
 
I cant remember if I set this up myself or not, but on my D300, the bottom button on the front of the camera below the DOF preview button. Hold it in and the lcd changes to show number of frames and exposure for bracketing.
 
No I was definitly in manual, Digitall (on here) was with me and he tried it as well, he has been a D300 user for a few years and he had never seen it before. Sorry I dont have any images to display I deleted all the bad one's.
 
Sounds like you was shooting in Aperture Priority mode to me, but like Joe T says - some sample images with EXIF would help
 
you said you deleted the bad ones so put up a good one also in manual mode lets see if you have anything set wrong ...we are just trying to help i know its frustrating :bang:
 
put up a JPEG untouched from the camera, and we can tell you what what the problem is. don't re-size it or edit it. Straight from the CF card.

The JPEG will have all the info.
 
Just been through them and found 1 I had not deleted

Being dragged down the club now by her indoors, be back about 11.30 ish Alan:D
 
I can't see anything wrong with your setting there, spot metering, manual exposure..I can't see an obvious problem.

Please put up a 1/80 sample (do a file recovery on your CF card to retrieve one)
 
opanda reports theres auto exposure bracketing of -2ev applied in that last jpeg

dunno if that's causing the issue?
 
Yep, its definately an issue with bracketing.

I just tried this on my D300 out of interest, and with a bracketing sequence this does override the dialed in manual setting. Actually quite surprising!

So sketch145 had it right.
 
Ok guys what do I do to sort it out, remember only just had this camera so its very new to me, :shrug:

Click to expand...

On my D300 I have the Fn button assigned to Bracketing.

If you do too, press Fn, and the dial will show something like 3F, -1

Use the front dial, so the 3F becomes 0F (thats bracketing off, 0F)

Suggest you read the manual tbh as well!

This is assuming your D300 is set up the same as mine!
 
Thanks for all the helpfull replies, I have been out with it today and all seems fine.
