Exposure lock -- perminant

[richard_dulkin]

<p>I own two Nikon d-700s and a d-750. All my photographic work is done in the studio (95%+) with strobe lights. These are Paul C Buff Einstein 640s six of them. The lighting in the studio is controlled by a commander unit for PCB also such that when the duties of these units are reconfigured the lighting always comes out for an exposure of 1/200 sec @ f/9. So all three of bodies with their different lenses start of at that correnct exposure.<br>

Here is the problem, those pesky front and rear command wheels on the Nikon camera bodies get changed during the photo session with a model. It is done in handling the cameras and since I am not a pic peeper between each shot, the exposure gets changed. Is there a way to lock the exposure <strong>permanently</strong> on those Nikon bodies. I am from the old school with Rollie-Cords, Hasselblads, etc. that had EV locks on them. You had to physically change those settiings by design rather than by accident.<br>

It would seemed that the digitally and electronically controls camera would have an area where you could permanently lock onto a predetermined exposure!<br>

<p>Tape.... glue...?<br>

No, as far as I know there is no way to lock exposure. At least, not on my D700. Not 100% sure for the D750, but given that is a touch lighter on controls than the D700, I doubt it would have it.</p>

<p>Some Nikon DSLRs have a lock button (designated "L") which allows you to lock a number of parameters so that they cannot be changed without releasing the lock. You can use this to lock shutter speed and aperture; I do this when working in the studio. Press L and turn the dial that controls the parameter that you want to lock by one click. To release the lock, do the same again. The D3 series and the D810 at least have this feature (in the D810 I've reprogrammed the record button to the Lock function).</p>

<p>To my surprise, D700 has a menu setting f8 for, optionally, both of those :-)</p>

[Wouter Willemse]

<p>Well, cool, so I was wrong :-)</p>

[rodeo_joe1]

<p>Menu item F8 is the way to go. The "L" position on the rear switch only locks the AF point selector joystick. It has no other function as far as I'm aware.</p>

[rodeo_joe1]

<p>Looks like the shutter/aperture lock menu option has been omitted from the D750. Taping over the command wheels might be the only way to disable them on this camera. Takes me back to the days of taping the X-M flash-synch lever in the X position on Compur shutters - except there were many more ways to screw up in those times.</p>

[richard_dulkin]

<p>Thanks I will try the f8 function on the d700. Can another function button be assigned for the d750?</p>

<p>I keep a roll of gaffer's tape around for just such situations. Just tear off a small strip and cover each command wheel. Comes off easily later without leaving residue.</p>

<p>I am afraid that exposure locking such a Custom Setting f8 on the D700 is available on the "pro" bodies only. On the D2 and D3, etc., there is a dedicated L (lock) button. I just checked the D750 and D7200, and I wasn't able to find that Custom Setting. If I overlooked something, please point it out.</p>

[richard_dulkin]

<p>Thanks all for your help! Will do the f8 solution for my D700s and Thanks Barry for the suggestion about gaffer's tape I was trying to avoid the use of electrical or duct tape on my camera bodies but will get the gaffer's tape for the D750...<br>

<p>i have been taking photos in some rough conditions..this has never happened to me with nikon.<br /> with canon yes, the wheel of doom does do weird things if not locked.</p>

<p>in a studio..<br /> what is it that you are doing i wonder? <br /> well..i guess somethings must not be told anyway ;)</p>

<p>go for the tape, that does always help.<br /> i would recomment something that does not have the strongest glue ever.</p>

<p>there are those textile based duct tapes, that are quite similar to gaffer's tape but do have a somewhat smooth<br /> surface.<br /> they do not leave tons of glue when removed from the camera.</p>

<p>i do not now the name but hope you have an idea for what you might wanna look out instead of gaffer's tape.</p>

<p>good luck</p>

[ilkka_nissila]

<p>Duct tape leaves a lot of sticky residue that may go inside the gaps for the wheels into the body. I would figure some other way to do it to avoid the bodies getting all gluey.</p>

<p>Easy solution, buy a D810. :-)</p>

<p>Some of those nice camo self-adhesive tapes designed to cover your 500mm f4 lens hood in tree leaf pattern are meant to leave very low residue on removal. That might look real pretty too...;-)</p>
