But what is the fine line between marketability and technological innovation... the innovation part comes from a demand, the prospect of a profit. So the two are very much married.
Yes and no.. often people build products because they think the world 'needs it' and they can make a buck along the way. Contrast that with 'the world tells us they want this'. The former ideal tends to be much more disruptors, and the latter tends to be 'add more knobs and switches' and all too often bringing products down.
Think about so many self-made inventions... they originate in a perceived need or gap in the market and they innovate to fit the gap. One of those 'you never knew you needed it until you saw it...'
I think we're in a dangerous spot in 2012, people in our society are under the impression that cameras can continue to get smaller and more compact without sacrificing quality. This may be 100% true on a consumer level, but the more kids who grow up with this mentality the less great work we may see.
How is 2012's position this any different from the last 50 years?
From full manual range finders... to things like auto-focus, motorized advance, interchangable lenses
From professional development labs to 24hr photo development to one hour...
The advent of 'instant' phototography...
Pocket cameras...
Disposible cameras...
The avalanche of printing innovations...
The first digital cameras...
The shrinking digital camera...
And during all that time... the art aspect of photography has escaped unscathed.
I really don't see an inflection point in 2012 or the near term at all. I don't see mirrorless as a disruptor technology either really... just a technology evolution that through incremental advancements has started to challenge what was the 'accepted minimum' before for viewfinders.
Does it stand to change what prosumer will use in the near term? Possibly. Is it inevitable? IMO, yes. The mirror+shutter in a digital body is a compromise to try to account for limitations in the ability to replicate the classic optical viewfinder. Overcome those limitations, and the mirror+shutter are pointless. It's only time.
At some point we're all beginners and as technology progresses and convenience trumps quality what will happen to these formats? They may very well disappear. I think year after year photographers who use these tools become more and more and more and more of a niche market.
I think what you are edging around but not seeing is... the separation between PRODUCTION and Art. The Art aspect will always be there, and people will build the niche products as long as they are economically feasible. And when they aren't.. small batch people take over. None of that is good for affordability, but the demand for an Art format isn't tied to the format's use in production or consumer uses.
You've already seen this with the production world moving to digital... and yet other film formats are still around. Paint is still around decades after the wacom tablet was introduced.. People still learn the guitar decades after synthesizers were introduced.
Art drives itself.. not from production demands.
