Originally posted by reh321 I mostly agree with you. The one area we seem to be seeing innovation in is "insanely high" ISO settings. If they can get this to work well, keeping noise under control {especially for JPEG} they will be opening a new frontier of sorts, because people will be able to take certain pictures needing neither flash nor {expensive} constant aperture lenses. I say JPEG especially, because this will especially open new opportunities to common folk, the people who take pictures for own use one sports season a year.
This is happening but slowing. The biggest gap was CCD vs CMOS with rougly 1-2EV improvement.
Now it continue but more slowly. More importantly even if the very high iso improve a lot the moderate iso not as much. it nowhere as important is on APSC the new 51200 iso look as good as the old 12800 iso as to how the current 1600 and 3200 iso look like. While it could be argued that K5 3200iso looked as good as K7 iso 800. Part was hardware, part was noise algorithms. I don't think even in JPEG there that level of difference of K70 looking as good at 3200 iso as K5 at iso 800... And theses iso settings are much more important. The problem is that if your 51200 iso setting much improved to 12800 isos that still basically... Not good enough anyway.
so that still incremental, and I guess it will continue to improve but if to get a very noticable 2EV gain take say now 10 year, you'll have incentive to upgrade every 10 years... Not every 3 or 5 years.
FF is a big factor and help a lot, but it was there for year so already in the pipe. They the price decrease but this one go slowly so again incremental. Before FF was 3000€, not so long ago it was 2000€, now there a few at 1000€. In 5 years there will be a few at maybe 500-700€ and many at 1000-1500€ but still incremental.
And even for high iso there something that is even worse. We improve continuously but people don't need infinite performance. Many people think their K5 is enough for all their photographic need. They will be back in the market only when their body stop working. Because they may have already a 17-50 f/8 they paid 300€ and get satisfied with they indoor anniversary shoots with a K5 and their cheap 17-50. Why would they upgrade if they are satisfied? They still get more performance than if they'd spend 800€ on a K70 + 18-5 3.5-5.6...
Again think of all theses K1 owner. They have the bigger sensor and the same improved high iso technology as in K70. Both combined their camera does well until 6400-12800 iso. There no many situations where honestly you need more than that, in particular as they are quite likely to have invested at least some reasonnably fast lens like a 300€ 28-75 from tamron or a 120€ DA35 f/2.4. They have already more than they need.
And the more the high iso improve, the more people will think finally APSC, or m4/3 or Q... Or their smartphone is enough. Now smartphones start to have 2 sensors and so have kind of zoom. They are the biggest area of research. If a breakthrough give 2EV improvement to sensors, the first one to benefit will be smartphones with the new generation as a consequence giving results as good as current 1". Combined with the now moderate zooming capabilities, even more people would call that enough and sale would go up only for smartphones, not DSLR or mirrorless...
Maybe the next thing photography related is not a camera as we know it. maybe that's something radically different. I don't know like a drone taking the picture for you automatically and that you could control if you wished... Maybe that the prototype of smartphones with a dozen sensors that - in theory - give as much performance as current m4/3 or APSC bodies. Maybe that's camera that scan and understand the scene really and built it overtime rather than taking a pure snapshot... We don't really know...
But today when you have the current camera, the next one look a lot what you really have and that why you don't upgrade.
