Adjusting the ISO?

[Oliver Rush]

BTW - I would vote for the ISO adj. on the Iris Wheel..and Not the shutter/ frame rate wheel ..were it ever to happen. The iris wheel will always be redundant to me otherwise.

+1,000,000 I have never even mounted a electronically controled lens on the AF100 (well, once I put one on for a second when I had my camera with me at B&H to confirm for myself that they do actually do something, lol) as I basically only use nikon primes with it... I would love all those buttons for lens controls to be mapped to something useful, and have always thought that if variable ISO was on the camera, that would be a great place to adjust it. Maybe use the auto iris button to toggle between functions/lock the wheel.

Considering that some are using ISO as a replacement function for an Iris ( aka. Aperture Ring on a lens) ...its only logical.

Well - sometimes the aperture setting is not a exposure decision but a creative one, especially with a large sensor camera with more control over DOF than a traditional ENG camera and one rather control exposure with ISO and ND filters.

I am personally not a fan of that trend... I find too much diffrence in image with major jumps in ISO in a scene for that to be useable... but like you I still want to do something with that button.

Yea, but with built in NDs, you can still get good control of DOF using the built in NDs and three ISOs. I usually keep my switch one stop intervals, and with the NDs and and those ISOs, I can control DOF to whatever look I desire. The diffrence in DOF between a shot at f1.4 and f2.8 (2 stops) at 15ft on a 50mm lens is about a foot, so having to settle a stop either way is not a big deal in a run and gun situation where going into the menues would be an issue... that said, I want a to have the ability to have ISO on that wheel, but I dont feel really constained by the current layout... more bummed about having unusable buttons.

Indeed it is more common to first select your ISO-value and work with a matte box/ND filters when using a fixed apperture(desired DoF) to set your correct exposure. But IMO it is very handy for the "newcomers" to be able to dial the ISO

You can use built in NDs and ditch the matte-box... frankly I dont think it is the best habit for a new comer to get used to constantly switching ISO to fine tune every exposure... IMHO it is better to try to shoot and keep your exposure consistant before it hits the film... that is why they had us shooting on reversal film back in beginning film classes... Shoot it, develop it, cut it (by hand on the steinbeck), and project it. There was no tweaking it or correcting it in post or changing the ISO between takes. Changing sensitivity required short-ending the film in the camera, and reloading it. By no means an efficent way of fine tuning exposure. You picked the best stock for the location, and worked based on that with the right lens/filter combination.
