Sony's ZV-E10 II Double Zoom Lens Kit in black held the number-one position in BCN's September ranking of interchangeable-lens camera sales in Japan, extending its run as the country's best-selling mirrorless camera across the retail data BCN collects.

The full September top-ten, published by Tokyo-based market tracker BCN, reads as follows:

• Sony VLOGCAM ZV-E10 II Double Zoom Lens Kit (Black)
• Canon EOS R10 RF-S18-150 IS STM Lens Kit
• Canon EOS R50 Double Zoom Kit (Black)
• Canon EOS R50 Double Zoom Kit (White)
• Olympus PEN E-P7 EZ Double Zoom Kit (Silver)
• Sony α7 V Body
• Fujifilm X-M5

BCN aggregates point-of-sale data from Japanese electronics retailers, which makes its monthly tables a useful proxy for where consumer yen actually landed — not what manufacturers shipped or announced.

What does the ranking tell working photographers?

Three patterns stand out. First, kits dominate. Every entry in the top five is a bundled zoom kit rather than a body-only sale, a signal that Japan's volume business remains entry-to-mid-tier, first-time-buyer driven. Second, Canon's placement is deep: the EOS R10 kit at number two plus both colorways of the EOS R50 double zoom kit give Canon three of the top four positions and strong APS-C throughput. Third, the only full-frame body on the list is Sony's α7 V, which appears at number seven in body-only form — notable given the camera's recent arrival, and evidence that enthusiast demand for the successor to the α7 IV is converting into retail sales in Japan.

Olympus's PEN E-P7 kit at number five and Fujifilm's X-M5 at number seven round out the table. Both are compact, style-first bodies, consistent with the same entry-level demand the rest of the list reflects.

Why one market matters

Japan is a single market, and BCN's data covers domestic retail POS, not global sell-through or online-only channels. Read it that way. Still, the composition of this table is a reminder of where unit volume actually lives: sub-¥200,000-class APS-C kits and vlogging-first bodies, not the flagship glass that dominates trade-show coverage.

For businesses calibrating inventory, training or service offerings against consumer demand — rental desks, used-camera trade-in pricing, workshop instructors — the top seven show kit lenses and doubles as the default purchase path. The α7 V's body-only placement is the one data point pointing upmarket, and it is worth watching whether Sony's newest full-frame body climbs in the October table as supply widens.

BCN's next monthly release, covering October, will show whether the ZV-E10 II's streak survives the holiday buying season.
