The camera you currently own is enough.There is no such thing as a "lingerie shot camera".
I can imagine your drycabinet... Top shelf is the "lingerie camera" with "lingerie lenses". Second shelf is the "outdoor portrait camera" with the "outdoor portrait" lenses, then there's the "Landscape camera" with the landscape lenses, then the "Events camera" with the events lenses, etc etc etc etc :cheers:
