This is a short story about me wasting my money
>had a 200D with Tamron 17-50 f/2.8 and was really happy with it
>want to go mirrorless because muh eye detection AF
>buy a R100 with adapter
>it's kinda meh but my Tamron works with it
>meanwhile realize I rarely shoot wide
>my mostly used focal lengths are between 28-50
>ok let's sell it because it's big and heavy and I don't really need an IS
>buy a 40mm pancake
>nice
>later buy a 28mm, it's great
>had some cash to spare at the end of the year
>fuck yes, I can finally go full frame
>buy a RP
>regret it shortly after it arrives
>28mm is way too wide
>40mm is ok, but faces get really distorted when I get up close
>also have a 90mm macro lens which I rarely use
>it's actually great on FF, on APS-C the FOV was too narrow
>that's like the only upside of buying a FF camera
All this happened in about 6 months and I ended up with a gear I don't like shooting with. Shold have stayed with 200D. So yeah, think before you buy something.
