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..........

Ed :)
 
1-2m at 70 does sound a bit close.
 
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 ?
 
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.
 
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 :D 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. :D
 
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...

Just for clarity on both my 20D and 10D you can't. I cant comment for other Canon bodies or any Nikon, but don't doubt Arkays knowledge there ;)
 
Again all, thanks for your help, seems like you have solved my problem as I was saying before, so I'll just have to take a few more steps back and then compose with the Sigma F2.8 70-200mm.

Ed :)
 
Sorry - just to clarify - it can be changed in custom settings on the NIKON D1, D1x and H, D2x and H, the D100 and the D70.

I cannot speak for the settings found on Canon bodies.

It can be changed on the D200, not sure about the D70 though?? (i don't remember there being an option for it)
 
Just tried that....won't focus on anything now ;)
 
Then you've successfully selected Manual-Focus For Ever mode...
 
I'll try manual after I've sellotaped all the bits back together
 
On the D70, press the Menu button, go to the custom menu (pencil icon) and select the Autofocus setting (item 02). Finally, select 'AF-C' for continuous mode
 
Catdaddy - Arkady was talking about being able to select a focus type WITHIN AF-C (ie should the camera give priority to taking the shot or acquiring focus)
 
Am I mistaken (if so, please say!), but I thought that's exactly what AF-C gave you... (as opposed to AF-S mode, which gives priority to the auto focus...)
 
Is it not AF-S will only focus the once with button half down, even if you move, yet AF-C keeps trying to focus ? So sounds like Arkady is on about a subsetting for AF-C that can allow/disallow shots if focus is not found
 
Correct - the default for AF-C is release-priority.
the default for AF-S is focus-priority.

Going into custom settings you should be able to alter the default so that the camera ensures the shot's in focus before releasing the shutter even in AF-C.

Bear in mind I also have about five different sub-settings in my AF-modes that the D100/200/70 don't have.
