Is there a risk of damaging the lens by overriding the value (I'm assuming the reported value is 108 and I'm trying to force a larger aperture value of 96)?
Here's the avtest log (up to around f/2. .
I got the f/1.4 Canon EF-M 32mm lens. Here are the 23 and 29 values for f/1.4, f/1.6 and f/1.8 (the f/2 till f/8 values are the same as the 22mm lens).First column is 23 values, second is 29.108 96132 128156 160
I'm attaching an image I took using CHDKPTP GUI that shows the two values at f/1.4.
f/2 is still differently exposed compared with the others. Here's the log.
How can I turn off lens correction (is it part of the regular Canon menu or the CHDK menu or in both and if so how does one access it)?
Incidentally, is it possible in the GUI of CHDKPTP to use the touchscreen to change the focus region (I couldn't figure out how to use the touchscreen at all)?
Also, how does one change shutter speed, aperture and ISO in the GUI of CHDKPTP in manual mode (which sequence of buttons does one need to press)?
