Who should buy what
X-A7 (2019)
- You want an affordable first mirrorless with decent video capabilities
- You shoot a lot of selfie-style content or vlog on a budget
- Note: no viewfinder and limited lens support — the X-T30 II is a better long-term investment
OM System TG-7 (2023)
- You dive, surf, kayak, ski, or hike and need a camera that genuinely survives anything
- You want a waterproof backup or travel camera that doesn't require a separate housing
- You need a rugged compact for adventure, outdoor, and underwater activities
Ricoh GR III (2019)
- You shoot street, travel, or documentary and want APS-C quality in a coat or shirt pocket
- You want a camera you'll genuinely always carry without thinking about it
- You appreciate sharp, characterful images from a fixed 28mm equivalent focal length
