Yep, check back here...I will have shutter/iso up here for all to see. What I will test.

The sylvania dimmer with cloth and cavision polarize filter before entering live view.

The sylvania dimmer with no cloth and no filter while in live view stopping down all the way down to f22 then opening up the iris, while going to +2 down to -2
Will have it by end of night. Formatting computer and filing taxes today.

okay, just letting you guys know, i didn't forget, i did the test, now i just need to export some grabs from the video. here are the results from the actual pictures to compare the video to. interesting results tonight. this is what i did.

i placed the sylvania light wrapped around in a cleaning cloth, so it's an even surface and not as bright, placed it in front of the camera and went through every stop from f16 to 1.4. at the +/- values from .7 to .-7. I didn't go any further than that cause the results beyond that, wasn't doing anything different from .3 to .7. but hey, this is free for you guys, so no bitchin anyway.

the cool thing so far. after you stop the lens down and lock your AE, this will give you your shutter, when you open the lens up, this adjusts your iso...sort of. of course, the brighter the source, the less noise, but not necessarily different iso, but this is how i'm picturing it. anyway, here are the first set of grabs from the acutal photo NOT the video.

Okay, here are two quick grabs from the VIDEO before entering LV. The first grab is very close to 1/50 and 1/60. It's just around 10 small steps as 1/50 is 11 steps and 1/60 is 9 steps. Steps are the small lines in between each square on the oscilloscope. Second grab has a really high shutter. More than 125. It's at 4 steps whereas 1/125 is at 6steps. More to come, just gotta head out to work now. Sorry.
