Something to keep in mind: the lenses you have listet are alle only APS-C compatible and therefore would go into crop mode on an A7C. You can use the lenses on the A7C but it would beg the question: why buy a FF camera to only use it in crop mode?
Regarding “digital remake of some older camera”: there are a lot of APS-C and MFT cameras that resemble older cameras, like the Nikon Zfc, which will have smaller lenses because of the smaller sensors. A good example is Sonys 20mm F2.8 which is super small but only APS-C compatible.
I had the Sony Zeiss 35mm f2.8 and for FF I think it was pretty compact. You could also look into manual lenses, for example the 50mm f2 from TTArtisan is very small and affordable.
„The study’s limitations included its reliance on self-reported dietary information, which may be affected by participant’s memory or recall and may not accurately assess typical eating patterns.“
This seems like a very critical limitation for such a clickbait title. Shouldn’t the exact tracking of the amount and quality of the food be a crucial part of such a study?
