Fujifilm x t100 vs fujifilm x h1?
The X-T100 and X-H1 both use the Fujifilm X mount and APS-C sensors with almost the same resolution, about 24 megapixels. The main difference is stabilisation. The Fujifilm X-H1 has it built into the body, so every lens you attach gets it, and its big grip suits longer lenses. The Fujifilm X-T100 has no in-body stabilisation, so you'll want stabilised lenses for slow shutter speeds.
If you want a simpler body, I'd pick the X-T100 and pair it with a lens that has OIS, like the Fujifilm XF 18-55mm f/2.8-4 R LM OIS, which covers most everyday shooting. If you shoot handheld in low light or use lenses without stabilisation, the X-H1 earns its grip. For reach, the Fujifilm XF 50-140mm f/2.8 R LM OIS WR is a strong partner for it.
