Went to the autosport show this weekend and run into a couple of "issues".......So I thought I'd ask you if you knew whats going on? I personally thought it was lighting problems but I'm not to sure now.

Basically the camera focuses but then the d70 decides not to take the photo? I decide to then move into a different position its all okay? (into more light)

The lens I was using was a Sigma F2.8 70-200 standing about 1-2 metres from the subject, settings were ISO 200 @ F2.8 on aperture priority.....

The internal flash on the D70 is not to bad imo, infact I was pleased with the results it gave me but it some areas it could have been a tad more powerful and produce more natural colours? if that kinda makes sense? dunno........

I'm hoping for my birthday that I may get some money which I can put towards a seperate flash! Perhaps a sb600 or sb800. Not to clued up on that area but I like the idea of these adjusting to the current light environment which tbh will help me loads (I think)

Any ideas what happend here?

Thanks for your help..........

I think you may have been too close to the subject, and the lens couldnt focus that close.

1-2m at 70 does sound a bit close.

[Dave]

Did you hear the beep for focus (if audible switched on), otherwise the relevant dot lights up on screen to show focus is in place ?

[digitalfailure]

Aye, does sound like you were a tad too close for the lens to operate, the Sigma site says 180cm minimum distance.

It can be difficult to take in all the information in the view finder when your concentrating on the image and whats doing on around you.

[Venomator]

The guys are right - it may sound like it is trying to focus ... but unless it beeps or the 'in-focus' indicator in the viewfinder lights up it will not fire - D70s is same in this respect.

...unless of course you were on AF-C mode

Nice one all, I think you've solved my problem, infact you have.......... I remember being pretty close now when the camera decided not to take those even though it focussed! However when I moved and was then a bit further away all was fine

I've turned the "beep" off on my D70

Thanks again all.......... (now a happy ed)

errrrrrrr whatcha mean?

I turned it off as I got told it can be "off putting" I normally just use the viewfinder and keep and a close eye on the focal points

LOL as long as you either use the Beep OR keep an eye on that green 'In focus' light in the viewfinder - no probs!

I prefer to be beepless.

If it was dark, the camera may not have locked on in a particular AF mode. Even the D2x does it sometimes in dingy conditions with plain subjects (walls etc with little detail). I have to use the manual override on the lens in those cases.
The camera's default stting is to disable release in certain AF modes if the camera doesn't lock focus. Focus-Priority. In other dynamic AF modes, the camera defaults to release-priority, whether the focus is locked on or not.

To my knowledge in Continous focus mode the camera will fire whether the shot is in focus or not. Only really applicable to tracking fast moving objects one supposes.

You can change it in Custom settings...
