Weird shake

Hi there- so this past Saturday when using my sigma art 24-70 I noticed a weird “shake” issue happening. When looking through the viewfinder and attempting to zoom/focus on something the whole scene in the view finder would shake and then settle. I thought it was my lens so I have shipped that out for service, however I just put my brand new 70-200 on the body and I’m noticing the same issue, although less prominent than with the 24-70.... help!!! Is this a body issue that I need to send the camera out for?

Welcome to the forum. Does it make that shake when the VC is off? That is the only thing that I can think might make cause an issue. I do notice a difference when the VC on my 70-200 G2 Tamon is off, but I would not call it a shake.

Thank you! I assume VC and VR are the same? If so, no it does not do it when the VR (sigma brand lens) is off. Is this normal when it’s on? I’ve had the 24-70 since last October and have never turn this off and all of a sudden this was an issue.

I sent the lens to sigma yesterday to be looked at, however I just tested this theory on my brand new sigma 70-200, shake happena with its on, does not when it’s off.

You should notice shaking initially for only a few moments when the VR is engaged and the shutter button held part way. Once the VR settles in, the image in the viewfinder should then remain steady. You don't want to press your shutter button until the shaking has stopped.

If both lenses aren't stopping after a few moments of shaking, then the issue might be with the body's ability to handle VR rather than the issue being the lenses. If you have a camera shop near you, see if they can take a look. Maybe they would have a few used lenses you could try to see if there is a difference with the VR.

By the way, did you recently update any firmware on the body? If so, that might have changed the compatibility with third party lenses.

The do stop. It’s like a one time shake and then after a few seconds it almost resets and then if I try to focus again it will do it again. I haven’t done any firmware updates. I think why I’m most concerned is this never happened previously with the 24-70.

That's the way VR works. Maybe you never noticed it previously?

VC is Tamron's acronym for VR. BTW the same thing happens with my Nikon lenses with VR. It is slight and I rarely notice it.

Welcome aboard. Enjoy the ride.
We look forward to seeing more posts and samples of your work.

The main question is, "how do your pictures look?" If they have suddenly gotten worse, you might have a problem.

Without seeing it, it sounds normal. I find it more pronounced on my Sigma lenses. Where I really notice it is with my 150-600. If I focus, then sit and watch while waiting for a bird to turn his head, I'll get a very annoying shake/jump as OS drops off along with the meter turning off. Then I'll get a lesser shake when I activate focus again and stabilization kicks back in.
If you are getting this jump a few seconds after focusing, increasing the meter on time might give you more time to zoom/recompose before it jumps when turning off. You're not on a tripod, right? That can make things even worse.

Sigma has a history of firmware issues with Nikon so be sure to have the latest updates to the lens software. VR has its uses but also limits of effectiveness. Regardless of what the manufacturers claim there are fewer applications where it is best to have on than off. Outdoors in good light, shutter speeds are normally pretty high and VR actually increases blur faster than about 1/500. Worse blur almost always results when on a tripod or steady monopod. When panning it can degrade images.
Nikon VR generally has a fast settling time but suffers alike all in action shots where AF is continuously focusing. In the studio or with flash or strobes turn it off always. The subject is frozen by the very short burst of light so any slower period movement result is differences from shot to shot.
Only turn on VR when hand-holding with steady subjects(some vr has an Action setting for panning) in the 1/15-1/500 shutter range. Slower shutter speeds if not using flash really should be for very still subjects and tripod for sharp images. The manufacturers claim 4-6 stops of slower speed for hand holding but in the real world that is nonsense, a range of 6 stops is out of the shutter speed range where it is useful.Those are marketing stops not exposure stops.
Fast lenses wide open are hard enough to handle for crisp shots and good technique and a still subject play a more important role in getting those as sharp as possible. Fast apertures are primes usually, and many benefit from a simpler optical formula so produce very sharp images because they do not have the added variables of moving elements that VR adds
The only time VR might help with flash is when flash-subject metering is only down 1-2 stops below ambient, such as when using iTTL BL balance flash for fill.
Do a scan of random images in your gallery and not the shutter speeds, you might be surprised how many are out of the VR range of usefulness. Outside that range, it detracts from sharpness. All your action outdoor shots probably were shorter than 1/500 so were actually hurt by having VR turned on.

My D750 'sometimes' has a slightly more pronounced lock on the subject, than my D600 has. Even though some of the D600's around the world had a shutter lube/shock absorbent (or whatever it was) problem, mine didn't, so I decided to keep it, yes even after I got the D750. I mean, although it didn't need it, I got the shutter mechanism replaced under the product recall 3 or 4 years ago, and today it still impresses me. It just seems to take great photo's. Why spoils things..?? When the D600 locks, it's like time just stood still all of a sudden with a "beep beep" to let you know, silky smooth, while the D750 'sometimes' has a sort of slight shunt (almost like a little jolt) to it's lock, usually more noticeable if it overshoots the mark and has to hunt a bit to find the lock. It kind of lets you know "I got it".. I can't see anything wrong with it, as it sometimes has quite fast lock times compared to the D600. Maybe it's just the share speed of its lock times that's doing it - the price you pay for speed. I mainly use the 24-120mm lens, which I bought when I got the D600,, just love this lens even though it's not really a world beater. I also use a 70-300mm and I think it might be a little more pronounced on this lens at times,, not much though, and under the same circumstances (hunting) as the above. Hadn't really noticed it too much 'til I looked at this thread... I just love both camera's and I'm so glad I decided to keep the D600 to compare them against each other. Hope soon to lay my paws on a D850,, maybe.. Fingers crossed...!!!
