Lensbaby

Hi i'm a Newbie to Lensbaby,
I'm just got my lensbaby composer with 2x glass. I'm using a Nikon D300, I've been told that it can be used in aperture priority just to get started. The question I have is, if I don't use the disk what aperture would the lens be at as if I used the disk of "2.8" it would be 2.8...without the disk would it be 2.8 or wider..just curious.
Thanks,
Ken

I have read in the lensbaby lit. that without the disc the F-stop would be 2.0. Aperture Priority just "reads" the current amount of light and calculates the exposure, you may want to do some +- adjustments to achieve the exposure you want.

Without the disc, it should be f2.0.

Ken, because the aperture does not close down during exposure, in theory, once you find the aperture setting that gives U correct exposure that setting can remain constant no matter what aperture disk you insert. IN THEORY. :) tony.

Tony, If I am reading you correctly, the theory you stated here on the discs means that with a good exposure in one disc I just follow the aperture change with a corresponding shutter adjustment (slower or faster as needed). Which is what I do with my Nikon 3100 in Manual, tweaking as needed according to the exposure histogram.

Am I reading you correctly?

Tony, How true..Like using a film camera back in the day.
