AETTR bug when change F-stop in 650d
Created originally on Bitbucket by Bank_T (Bank Thanat)
Hi. My name is Bank.
I've been using ML for a while. Thank you guys for such a great work!
today I found a bug with AETTR. I went for taking macro pictures with my camera mount in a tripod. when I shot at fully open fstop everything seem right. The camera provide a great picture because AETTR. unless DOF of this pic is a little blur more than I want. So I increased f stop number. The thing is AETTR doesn't change shutter speed to compensate increasing of f-stop. it using shutter speed that used when fully fstop open. (I'm using press set btn to activate) no matter how many times I tried to restart camera or pressed set button. So I shot it as It is. the pic went a little underexposed. Then I have to lower shutter speed myself by I looking in histogram and got it as I want.

My AETTR Settings are
-
Trigger mode : Press set
-
Slowest Shutter : 10"
-
exposure target :-1ev
-
Highlight ignore : 0.1%
-
Allow chipping : OFF
-

-

camera setting M mode iso 100 f widest at 3.5 and increase it to 8 then found this.
So, Can I assume it as a bug? or AETTR only work with fully open aperture?
Thanks in advance B
