I’m interested in trends in digital imaging. One problem 35mm digital faces is lens vs. sensor resolution and similar trade-offs. On DX, something like 16 Mp will be the upper limit beyond which only a very small handful of very specialized lenses will be able to provide enough resolution to keep up. The end is near, folks! On FX, in the center (a DX crop), roughly that same limit on the cropped sensor will apply, leading to something of order 32 Mp total. However, by then the corners will be a catastrophe in all but a small handful of the most exotic and expensive lenses. Perhaps variable resolution between cropped and full-frame modes will become a norm. Still room to grow, but the noose is tightening here too. At that point, there will be only a few possibilities: Perhaps the best possibility is that people will accept that it's over-all quality that counts, not mere resolution. People will accept that something like 10 Mp on DX and say 16 Mp on FX provides the best over-all corner to corner quality in a compact (35mm DX or FX) format. A number of existing lenses will be able to cope well, and peace and prosperity will reign. A more likely possibility is that most people will do what they have always done: buy the specs that are pushed (24+ Mp cameras in the near future), put a super-zoom on it, complain, and go on to make their 4x6" prints or low-resolution myspace pictures anyway. Another possibility is that some people will go back to using primes or limited-range (~2x) optimized zooms, which would hopefully be redesigned to offer sufficient performance on high-resolution full frame. These will be very expensive, large and heavy to cope with the sensor demands. Another possibility is that lenses will become slower and slower in an effort to provide sufficient resolution in compact, lighter and relatively inexpensive packages (a trend we have seen already in variable maximum-aperture zooms). Given digital's high low-light quality, there isn't as much need for f/1.4 primes and f/2.8 zooms now except for specialized applications. And, the most likely possibility of all: Still cameras will become an anachronism. Point and shoots, SLR's and video cameras will merge. People will focus on HD digital video for their web sites and home theater servers. Video cameras will be able to take individual very high quality still pictures, but this will be a rarely-used feature and will be the result of merging video frames together anyway. People will stop printing photos almost entirely as they transition to ubiquitous wireless digital photo-frames. Most lenses will suffice to take HD+ quality. In the last stages, the few cranky old men who scoff at video (I will be one of them!) will fawn over Nikon’s final few dedicated still camera models (selling used for pennies on the dollar just as film bodies do) or migrate to even crankier use of medium-format digital. Cheers!
