Camera broken in odd way?

Hi,

I have a strange problem with my camera, I have the following lenses:

Nikon 50mm/1.4
Sigma 30mm/1.4
Sigma 10-20mm/3.5
Sigma 50-150/2.8

I sent my camera off to Nikon to be serviced and when it came back, none of the Sigma could focus sharply at anyting in the distance. Infinity is just a blur on all of them but the Nikon lens is still perfect. At least, I think this happened after the service unless it's just slowly crept up on me and I didn't really notice.

The 50-150mm especially used to be my sharpest lens but is now just hazey at best.

What would cause this? Is it the camera or the lenses? And is it fixable?

Thanks for any advice
 
What camera is it? Has it had a firmware update?
 
Probably been reset to factory settings, most likely have to microadjust your Sigmas.

The problem is the Sigma lenses are no longer linearly focusing, i.e. if I adjust for infinity, indoor photos are blurry...

Defineately odd, if your Nikon lens is OK, could be something in the firmware thats causing it, I have updated the firmware on my 7100 with no problems after, most of my lenses are Sigma's.
 
Could be a micro-adjust needed but as it's all of the Sigma lenses I doubt that, I would be more inclined to think that the firmware update has rendered the Sigma lenses 'out of sync' with the D7000. Can you manually focus to infinity?

Good question, I tried manually focusing using the green dot but I haven't actually tried just focusing for infinity.

The thing is, it's been back to Nikon after the original service explaining what the synptoms were, and they returned it with "No fault found".

You wouldn't be the first to get 'No fault found' when there was still a fault.
Ring them up and ask them why their service has affected all of your Sigma lenses.

I suppose I'll have to speak to them again. I'm just not very keen if it isn't the camera's faulty, just trying to think of what it could be.

Third-party lenses may not be compatible with 'future' upgrades to Nikon (or other) bodies so that could be the issue ... you having nothing to lose by asking them, except the cost of a phone call :)
 
I :agree: nothing to lose,i sent of my Fuji XE-2 came back with no fault found but it was still their,2nd time it got fixed :)
 
Also try using live view but do seem to remember that when I had a d7000 live view and 3rd part lens was hit and miss
 
I had to fine tune every lens on my d7000! Great body ! That was only issue I had with it!
 
Doubt Nikon will admit anything when it comes to problems with a 3rd party lens in fact I doubt they'll even care and will most likely blame incompatibility with the sigma, have you tried to possibly re-install the firmware (if possible) in case there was an undetected issue with the update itself?
 
Thanks for everyone's suggestions. I'll try the following this weekend:

- Manual focusing
- Live view focusing
- Playing around a bit with fine-tuning
- Just remembered my step-son has a D5100, will see if he will let me borrow it

I wouldn't know how to do firmware but will look in to it

Thanks
 
If you get nowhere with Nikon it maybe worth speaking to Sigma to get the firmware updated for your lenses.
 
I tried some of the suggestions yesterday:

- Liveview: Totally broken on the Sigmas. The lens makes a little jump forward on the focus ring but the green square on the monitor then starts flashing red... Works fine with the Nikon lens

- Manual focus: Using the green dot, still blurry. Moving the foocus ring manually slightly back, can get things in focus.

Still haven't tried the D5100

Older Sigma lenses are know not to work with LV. Did they work before?

No idea, I don't use Live view... I know auto-focus was near useless when shooting video but I thought that was just the way the camera worked.

EDIT: Actually, I must have tried LV in the past, don't remember it being completely broken, but I could be wrong.

And have you checked that the FW is the latest?

Do you mean FW on the camera or lenses? Nikon updated the camera FW, don't know how to do the lenses...
 
Just tried them on the D5100 and it's the same, so basically all my Sigma lenses are knackered...
 
Was there a problem with your camera which required you sending it for servicing?

Contact Sigma regarding this issue and see if they will update the FW for you. I seem to remember this costs around £30-40.

This also depends on the age of the lens - older Sigma lenses cannot be updated.
Live view is an ongoing issue as Nikon constantly update the focusing algorithm and do not release the information to third parties. Sigma have to reverse engineer the AF algorithm to make their lenses work with it.

It's unlikely they'd all be out, massive coincidence.

I've never had to MA a lens, including Sigma's.

Why don't you try rolling the camera back to an older firmware?

No,

Having had it for 3 years I mistakenly thought it would be a good idea!

For the non professional user id say there's no need to have anything serviced unless it presents a problem IMO!
