Yes there are a few on Amazon depending on what you meant by poster size. These are meant to fold up and fit into a camera bag and open up to about 8X11 and are laminated.
Do a google search for exactly what you said SX50HS cheat sheet.
Thanks. Yeah, I saw the 8 x 11 ones on Amazon, the only ones I found. I thought someone might have a larger one. I guess I'll have to get one of those, and print a larger size. Thanks again.
