Nikkor 50mm/1.8D - no manual control of arperture ring in Video Mode

Hi Guys,

i am fairly new to the world of DSLR and just got my D90 a week ago. Beside the stock lense i purchased also the Nikkor 50mm/f1.8D as it was highly recommended.

Now i try to record D-movies in low light conditions and i did try kholis guide to achieve low ISO recordings.

Now here is my problem:

If the lense is not connected to the camera i can open and close the Iris with the manual arperture ring. Once i connect the lense (with f22 and locked) with the body, the camera opens the arperture blades completely.
When i now turn the manual arperture ring (and i tried every Mode here) the arperture blades dont move.
Whatever i do with the manual arperture ring the lense doesnt react.
Is there something wrong with my Lense? Does the camera override it?

How can i adjust arperture manually with the ring when shooting videos?

Is it only possible with full manual lenses?

Is there a workaround for that?

Thanks for your help

Harry
 
hmm, works just fine with my 28mm 2.8 (i shot a mini feature in my film class last night using this setup), i also have a 50mm 1.8, ill try when i get home and report back.


I really love the 50mm, but for indoor stuff sometimes its just not wide enough, and since we only had an hour to write a story, select a location, setup and shoot i didnt have much time to be changing lenses back and forht.
 
they should move when you're in liveview, otherwise they only close to your desired aperture when you take a picture.
 
i verified monday when doing some footage for class that it does move manually in video mode.

You will get the EEr error, but you can still shoot

Hi

I had the same problem with the 50 mm lense. I tried not rotating it all the when attacting it to the body. Then I could see it worked, and then when I rotated it all the way and made a click (attacted to the body) I could suddenly get it to work while in LV. I guess it is pretty much what you have done, but you might try this specific approch?
 
If your aperture setting (that is, electronically set) is at 1.8 before you go in to LV, your aperture ring adjustments will change nothing.

Try electronically setting aperture to another value (say f8), and then go into LV and then rotate the aperture ring - you'll see it changes and at f1.8 you'll see chronic overexposure. There is no substitute for A) locking exposure using a grey card lit by your key light, B) working with the picture settings and C) defining the white balance, for getting the shot you want.

NB - not in that order, however!
