Though the volume of interchangeable-lens 'Non-Reflex' cameras dipped 13.5%, in value terms this only represented a 5.5% drop, according to Japan's Camera & Imaging Products Association (CIPA).
Meanwhile, SLR shipments fell 17.4% in volume and 17.6% in value, compared to the same period last year.
Shipments of interchangeable-lens cameras to the Japanese market (included in the above figures) bucked the downward trend - with SLRs and mirrorless models rising 37.2% and 21.7% respectively over the nine months.
On a worldwide basis, the figures show that SLR shipments exceeded mirrorless models by almost five times.

The 'Non-Reflex' category includes mirrorless compact system cameras and rangefinder models, according to the CIPA statistics.
