Images from Amira and Mini, comparison and question
Posted: Mon Jan 30, 2017 10:46 pm
I have owned a Mini since May '16, and after having used an Amira about 10 months prior to that (pre 3.2k SUP update), I have noticed what seems, at identical default sharpness and detail settings, a different image aesthetic between the two cameras. The Mini, even when shooting at 2k, seems to my eye sharper, with more surface detail (skin blemishes, etc), than the Amira was.

Most noticeable are detail and edge sharpness differences. I do not currently have those lenses in my possession, but should in a week or so. Again, I believe have noticed the increased sharpness even at 2k in the Mini. Do you recommend different settings in the Mini to match the Amira? Is an exact match not possible due to differences in firmware or new processing? I would like to match the smoother aesthetic of the Amira most of the time.
