The XHG1 is essentially an XL-H1 without an interchangeable lens, but with a few updated features. The XLA1 also strips out the “jackpack” features.
This is very exciting as a complement to the XL-H1. The form factor looks good, you get all the quality of the XL-H1, and you save a few bucks. Sure makes the Z1U look a lot less tempting.
