Thanks a lot Danne and IDA_ML for the info!
Lua can be used to modify shutter, iso, other settings. If frsp enabled shouldn't make no difference.
The reason I ask is because on my 550D the FRSP (or even Simple low res silent pic) doesn't work with exposure bracketing nor focus stacking. Only single photo is always taken. But I also experience the bug with a black screen after FRSP shot and have to always return to Live view by half pressing the shutter button again. So maybe FRSP mode is really much more limited on 550D. That is great if it works with bracketing and other features on EOS M.
Longer shutter times than with 550d. Don't think so but not sure here.
What about the fastest shutter speed? I wonder if I could get at least the same results as 60D here (from 1/10 or maybe 1/30 sec to 5 sec):
https://www.magiclantern.fm/forum/index.php?topic=12523.msg122956#msg122956The reason why I avoid using FRSP is that this mode does not allow proper aperture control on some of my best lenses and I cannot stop them down enough for reasonable depth of field.
Yeah, that is a big limitation of FRSP. Actually I play with the idea of getting a used Nikon lens and adpater because Nikon lenses (I don't know if all of them though) have a little lever that controls the aperture. Some of the adapters make use of it and allow you to move the lever (with a bigger lever or ring) thus manually setting the aperture. But of course the disadvantage of manual lens is that you cannot do automated focus stacking and if the adapter is not perfect there might be a little bit of play.
Do you have any lenses where the aperture actually worked with FRSP? If so, could you please state their full name?
I prefer the 5k anamorphic setting in the Movie mode instead. The image quality degradation compared to FRSP is negligible and not perceptible unless you pixel peep at 100%. Even then, you will barely see a difference in image quality.
That sounds interesting. I looked a bit into it and if I understand it correctly the anamorphic 5K setting just crops the photo (or frame). What exactly causes the slight IQ degradation compared to the FRSP? Is it just the crop (resolution) or is there any bit depth degradation or even compression? This might sound stupid but I am gonna ask just in case
... is there any stretching or transformation applied to the image in camera?
What would be the highest resolution photo I could get with this anamorphic 5K setting? If there are any downloadable .MLV shots of the same scene and with the same exposure (one taken with FRSP and one taken with anamorph. 5K) somewhere, that would be excellent.
Are there any other problems (vignetting, artifacts, ...) with silent pics on EOS M (FRSP or anamorph. 5K) to be aware of like described here?:
https://www.magiclantern.fm/forum/index.php?topic=12523.msg122916#msg122916Plus there is a strange top-corner vignetting after 1/30 which seems it exists anyway in the all pictures in every exporuse although it isnt always very noticeable.
Again, thanks a lot guys for your help! I appreciate it. I am sure it will be useful to other users as well. I asked a lot of questions, don't bother with all of them if you don't know the answer, I will be grateful for any info.
