Let's face the reality: The Four Thirds system failed in the market.
Because it could not deliver what was promised.
The performance ratio of camera/lens size and quality has not been convincing.
m4/3 is better in that respect.
The interesting question is, whether m4/3 can survive in the future: The DSLM market is very small, declining, and overcrowded with lots of strong competitors.
And does have m4/3 really (enough) siginificant advantages compared to APS-C DSLM cameras?
Will the future market for m4/3 remain big enough for two, for both Olympus and Panasonic?
Or will one of them give up?
I don't know, we will see. But is quite clear that m4/3 will have the most pressure on it in the market of the coming years.
Camera-wise the film scene is a dead pool of water. We may never see any "serious" manufacturer releasing a "new" model again.
The film market is increasing again.
We've seen all the statements and new product announcements from the manufacturers like JOBO, Bergger, Adox, Kodak, Film Ferrania, Foma, Bellini, Tetenal, Fujifilm, ars-imago, Ilford etc. confirming this.
The manufacturers are investing in new and modern production capacities (e.g. Adox is doubling its factory in Germany, and they recently just acquired parts of the former Ilford Imaging factory in Switzerland).
Demand for used film cameras is also rising for lots of models. That will continue in the coming years. Therefore new film cameras will have increasing attraction for film shooters in the future.
And at the same time the demand for digital cameras has collapsed by 80% in the last years (and there is no end in sight for this trend). The camera manufacturers are now selling much less digital cameras than film cameras during the 90ies.
Therefore new market segments and increasing niche markets will become more important for the camera manufacturers in the coming years.
We will see a very similar development with new film cameras as we've seen with mechanical watches and turntables:
A strong comeback with lots of new models.
I expect new film cameras on the market in the next 3-5 years.
