Camera seems to have a mind of it's own!

I've had a A7iii for a few years now and up until recently all has been fine. However, when shooting in manual mode my camera changes the shutter speed after every shot, e.g. just taken a shot at 1/60th and immediately the camera set itself to 1/4000th without me touching it!

I have the camera set for BBF and the same change of shutter speed can happen when I press the shutter button.

Live View is on.

Any suggestions?

Many thanks!

What mode? PASM? Does it reset to the same shutter speed every time or does it vary? Is it possibly overriding you in some Auto mode? Does it do it in M?

There's no setting I know of that would make it do this. You could try to start over with new settings or try a reset. If that all fails, then maybe contact a repair shop.

I have a similar issue with an a7R III. It seems like I've had this happen with previous cameras, but I don't recall if that was the shutter speed specifically. With this camera at least, I've used a clip on the band of my hip pack when hiking, along with a strap, so I can understand the back buttons/dials getting changed. But not the shutter speed dial. I tried some canned air as suggested elsewhere as well as a bit of alcohol on a q-tip , but that didn't help. 

I guess it's five years old now, and since I dropped it on a hard floor last year and the media slot door won't close all the way (I think it landed on that lower corner and something became misaligned), not to mention tripping and landing on it and the lens several times outdoors (on dirt), I need to send it in and get an estimate anyway.

But the shutter speed changing is driving me nuts now, and it happens when I'm not using that clip, just photographing things in my yard or porch. I almost always have to use flash on that with my 90mm macro, and that particular ring flash with two heads doesn't have HSS, so 1/250 and sometimes that's not enough. But it changes by itself, and most of the time goes above that so I get a black image when I don't notice.

I have same problem with A7R4 in manual mode. No matter what shutter I set,it will once in a while take a long exposure and when the exposure is complete it can’t read the f stop, programmed butttons don’t repond. Only way to get it back is shut it off and take the battery out for 20 seconds or so.

Love the camera except when this happens. Thought was a low battery but it just happened and the battery was at 98%.

You might want to get a Small Rig bracket. It protects the camera and its great for mounting in portrait or landscape. Note the USB cover opened. I love the bracket.

      A7 IV Freezing

      By Cameratose · Posted

      AI sez: The CHIPFANCIER CFexpress Type A 4.0 memory card offers 1700MB/s read speeds and is VPG400 certified, making it suitable for 8K video and high-speed shooting. However, some users have reported limitations in frame rates with this card.  Don't know if that applies, but it sounds similar. Any chance on using/getting a different card? The A7 IV has a ridiculous buffer, it shouldn't slow down at all with a good card.

      Make sure camera and lens is updated to latest firmware.

      ISO Bracketing

      By Richard A · Posted

      ISO 320 is the A7R5's second base ISO setting. You will find at ISO 320 you will get better results than even ISO 200. I normally take a set of shots at 1600, 3200 and 6400 ISO. I am taking 60 light frames and 10 dark frames. I don't do any adjustments to the files before stacking. I really need to get organised and do some bias frames now. Here is pretty much my first successful Milky Way shot from a few months ago. I was combatting a bit of ambient light and quite a lot of cloud but I'm pretty happy with this. It was shot using my Sigma 16-28 f2.8 which is better at astro than I had anticipated, at ISO 1600.
