Presuming you mean the ability to use adapted lenses from Leica and other manufacturers, yes. But it's not entirely without some issues.
- To use adapted lenses means using the eshutter since Hasselblad X system lenses have lens shutters, there is no mechanical shutter on the body.
- While the field coverage of many lenses designed for 24x36 format will also cover (or almost cover) 33x44 format, there are no guarantees. You have to test each lens to see how it performs on the format. Happily, although many will NOT cover 33x44 without vignetting or falloff, many will cover 33x33 format with few issues.
I bought both Leica R and Leica M to X system adapters, as well as the XV Adapter from Hasselblad (to use V system lenses). The V system lenses are guaranteed to cover the format and work the best. I haven't done a thorough test of all of my M and R lenses, but the ones I've worked with most do work pretty well, presuming that the eshutter characteristics don't get in the way.
I find mucking with adapted lenses quite fun, but sometimes curiously disappointing. And other times, very exhilarating what I can get out of the camera with an oddball lens. I don't know that it's sensible to think that many many users will buy the 907x because of the lens adaptation possibilities, but it was an attraction for me.
