Fujifilm X100VI vs Leica Q3 Monochrom

These sit in different sensor classes, and that decides most of it. The Leica Q3 Monochrom is full-frame (746g (1.64 lb), $7,790) — larger sensor, shallower depth-of-field and cleaner high-ISO. The Fujifilm X100VI is APS-C (521g (1.15 lb), $1,599), trading some of that for a lighter, cheaper body and extra effective reach from lenses. Pick the format that matches how you shoot before splitting hairs on features.

Choose the Fujifilm X100VI if you photograph moving subjects — it adds AF subject detection for animals and vehicles that the other body lacks. Choose it if you shoot handheld — in-body stabilisation lets you use slower shutter speeds and steadies video, which the other body can't do without a stabilised lens. Choose it if you're budget-conscious — it launched at $1,599, about $6,191 less, freeing money for lenses. Choose it if you value portability — at 521g (1.15 lb) it's noticeably lighter than the 746g (1.64 lb) alternative for travel and all-day carry.

Choose the Leica Q3 Monochrom if you shoot action, sports or wildlife — 15fps burst keeps up with fast, erratic movement where 11fps would drop frames. Choose it if you shoot video seriously — it brings 8K capture (up to 30p). Choose it if you want maximum detail for landscapes, studio or large prints — 60.3MP resolves noticeably more than 40.2MP and gives more cropping latitude. Choose it if you prioritise shallow depth-of-field and clean high-ISO — its full-frame sensor is larger than the APS-C one, so backgrounds blur more and noise stays lower in dim light.

Video: the Leica Q3 Monochrom is the stronger video tool — 8K, 4K up to 60p and 10-bit internal.
