locking controls?

Hello, friends!

Is anybody facing the same problem: I often shoot in constant light conditions (studio shoots or concerts/sport events) and use M mode. But when shooting, I suddenly touch wheel dials. And I have tens of under- or overexposed images before I notice the fault. Of cource, if it's not more than 1/2-1 EV, it's recoverable when working with RAWs, but it's not very good for batch processing, and sometimes i need fast results (JPEGs) for press, for example, and it becomes a real problem.

So, the question is: how to lock the wheels?
The gear is: K3&K5

There's no option to lock the controls, unfortunately. You can change the e-dial mappings, but that wouldn't be of much help in this scenario. I suppose the best long-term remedy would be to get in the habit of keeping your fingers away from the dials except when adjustments are needed.

Adam, thank you for your reply! it's possible for rear wheel, but the front wheel is very close to shutter button

Perhaps a remote shutter release where appropriate?

You can use AE-lock in M-mode to avoid over/under exposure.
It will still let you adjust aperture and shutter speed, but exposure value will be locked, so both shutter speed and aperture changes when adjusting one of them to keep the same exposure value.

Fogel70, thanx for idea, a nice semi-solution, at least not to loose everything )

It might also depend on the lens.

You could if the lens permits, take the lens out of A mode, leaving the camera up in true manual. Since you shoot inconstant light no need to change aperture, and if you can disable one wheel then you should be ok.

The other option is to set your exposure compensation for what ever over or under exposure you are routinely using in manual, and then to put the camera in either Tav AV or Tv mode to set what you want for shutter aperture aperture or both and just let the camera do the work.

Manual mode is , for me, when you have time , the camera has TTL metering for a reason

if i was doing that, I would just take a sticky tape, something like electrical tape, and tape the dials...

Wired remote. Or flu card.

Can you show a photo of you holding the camera ?
Maybe you are holding it awkwardly or incorrect.

Thanx for all replies!
I can hardly imagine using remote, wired or wireless or flucard tethering, as I need to reframe, rotate camera, and to move myself from time to time. It's good solution for studio, but not the best for sport events.

you gave me an idea (with the help of other users ideas) to remap dials so the aperture dial will be in front and exposure in back, so with manual aperture exposure dial will be in safer position! But not all my lens allow it ((

Sorry, I dont But most of the errors are caused by me changing the camera (i use one tele and one normal lens with k3 and k5 simultaniously) or some other movements, not during the continous shooting, so I think i hold camera in the right way ))

One of the best ideas so far )))

Unfortunately, there are cases when it does not work. For example, when the person of interest is constantly illuminated, but background changes.

Of cource, if it's not more than 1/2-1 EV,
If you're using 1/2 EV steps, you might change it to 1/3 EV steps. This way each accidental click is slightly less damaging.

Rather than sticky tape - perhaps you could build a shield that you can place over the top of the camera to keep fingers away from the dials. You could use leather or plexiglass that you bend in a U shape and drill out where needed. Adding a couple of small patches of velcro to the front of the camera body would give you an anchor point. It's easier to visualize with paper and camera in hand. Imagine a device that was like a U or a [ where one end is longer and has velcro and goes onto velcro on the front of the camera. The shape is a little more complex, but that should help understand the idea.

I just got my K-5 last month and am getting used to it. I too have bumped the front dial when I didn't mean to. The K110D didn't have a dial there.
All I can think to do is to reassign that wheel to something that won't affect the shot and to just be more careful to press only the shutter. Practice should help. Fingers can learn a lot if you just practice. Use the green button more, that should help. Instant correct exposure.
Good luck!

I understand what you are talking about, i have a good visual imagination

I just did it, as the least complicated solution, will try this weekend at the event, if it will not help signifiantly, will try to make something to cover dials!
