I was looking at a few notes on the web.

I'm seeing the derailleurs:
FD-4403, FD-6503, & FD-6603 are rated for 52T max, and 22T capacity, with several people reporting a slightly wider range.

The A553 (RX100 Triple) seems to have ambiguous details, but probably is similar, although a couple of sites seem to be rating it as high as 26T.
