In 2011 Sony Discloses Basic Specifications of the "E-mount" for Interchangeable Single Lens Cameras
without Fee. This was done to help get to #2 in
2019 displacing Nikon.
In 2021 Nikon selectively
licensed their Z mount in the hopes of replicating Sony's success and get to #2 again. Let us see if this will be successful before the 2030s.
Both companies compromised because they had little or no choice at the time they made the decision to license their tech out. Google did this with Android where in the OS is free for consumers & brands to install to remove every possible friction or bottleneck to growth and adoption. Microsoft tried to compete and replicate their desktop business model of a
license fee-based Windows Mobile and failed.
Canon is #1 in
interchangeable lens cameras. They have little to no incentive to license with or without a fee to 3rd parties as their business model has them earning more selling 1st party lenses. In this respect they are following Apple's business model in the hopes of continuing to be the biggest profit & venenue generator in the perpetually shrinking digital still camera market.
Digital still camera market is experiencing shrinkage so every additional sale of a 1st party body, lens & accessory helps. Without this
economies of scale does not function in helping
push prices down.
>80% of the 30+ lenses each released from 2018-2022 by Canon & Nikon are
- faster
inventory turnover
- better
profit margins
The missing EF & F mount lenses that will be released on the RF & Z mounts in the next 4 years will tend to be
- slower
inventory turnover
- worse
profit margins
Why are they releasing their products this way? Because any for profit company want to get their
ROI faster.
