Pros & Cons Side by Side

OM System OM-1 Mark II Mirrorless Camera

120fps burst with blackout-free shooting — the fastest burst rate of any reviewed mirrorless
AI Subject Detection tracks birds and aircraft with reliability that full-frame alternatives struggle to match
Handheld High Res Shot produces 80MP images from a 20MP sensor using IBIS movement
IP53 weather sealing withstands heavy rain and dust — the most rugged mirrorless reviewed
Micro 4/3 telephoto reach: 300mm f/4 lens is equivalent to 600mm on full-frame — affordable wildlife reach

20MP M4/3 sensor — lower resolution and weaker low-light than full-frame alternatives
M4/3 system requires smaller lenses which limits the very largest apertures

Sony Alpha A6700 APS-C Mirrorless Camera

AI subject recognition AF tracks humans, animals and insects with A7 IV-level accuracy in APS-C
5-stop IBIS is exceptionally capable for an APS-C body — smooth handheld video
4K/120fps slow-motion at 5x from an APS-C body — previously only available in full-frame
Compact APS-C body with full-frame AF capability — the best APS-C camera Sony has made
Access to full Sony E-mount lens ecosystem including full-frame lenses for reach advantage

£1,300 is premium pricing for an APS-C body — Sony A7C II full-frame is the next price step
Battery life approximately 490 shots — carry a spare for full day shoots
Menu depth is complex — Sony's interface has a learning curve for new users
