Tip: Gaining 200+ shutter speeds with 'Highlight Tone Priority'
 

By using the lens twist method or the nikon lenses (with adapter) you can force the ISO to remain at 200 enabling faster shutter speed.

Testing with a 50-mm 1.4 lens using the twist method I could normally achieve 1/200 shutter speed at ISO 100 in the light of my kitchen.

After enabling 'Highlight Tone Priority' the camera is forced to use the lowest ISO of 200 thus enabling a faster shutter speed of 1/400 in the same lighting conditions.

The same would apply using a nikon fit lens.

The test yields no difference under normal camera operations with the canon lens fully attached.

You are the man. You also have a bright kitchen.

The question is: Will Canon EVER give you a repair under warranty.

Next: Exposing the 5DII to gamma radiation for extended battery life. :)

Hi Don,
It's true I do have a bright kitchen but I didn't say it way a bright picture.

I did point the camera up at the heavens last night using a very long exposure trying to capture some cosmic rays. Not sure it helped the battery life :) in the end I just made light trail pictures with the moon in an effort to make a Christmas tree shape in the night sky.

I do fiddle with this camera alot, trying to find some way to get it to do what I want. Now if I could just do the same with the wife!
