Is it possible to lock Shutter speed and Aperture settings so dials can't accidently change them?

Last time I was shooting with flashes I accidently moved shutter speed dial from 1/200 to 1/250. Small black stripe appeared unnoticed on all following pictures due to lag in wireless flash trigger (a piece of curtain). I want to avoid this in the future by locking SS and A.

If it is not possible, how do you personally prevent these changes from happening?

I am using Nikon D600.

(I know about AE-lock, but it controls automatic metering in [semi-]auto modes.)

The only way you can lock them is to put a piece of tape over them. And even that's not fool proof.

I'll argue that the only solution to this is to simply monitor what you're doing.


Having had a D300 and a D800, ive not seen this as a problem, as Dan says, there is no way to lock the controls, you just need to be a bit more careful and keep an eye on what you are doing - do you not preview images between shots?

Yes a bit of tape would be your only option.

The reason for the black bar is not wireless trigger lag - it is because the D600 has a maximum flash sync speed of 1/200th - this would happen with any flash.

    \$\begingroup\$ D600 has maximum flash sync speed of 1/250 actualy. You just have to change it in menu from the default 1/200. My wireless trigger is slow and can't handle 1/250 - it makes the black stripe. \$\endgroup\$ Commented Feb 9, 2013 at 19:38
