>>2960143> What about speed boosters? Are they worth their money?Depends on what glass you have or want to use with them, and in what situations.
They aren't really going to solve issues related to pixel size (like with diffraction or such) very well, and they're not going to make sharp glass cheap.
For your problem description, better just buy sharp glass for APS-C, or if that doesn't suffice, switch to FF and buy sharp glass there.
