Prediction · These are electronics-driven consumer goods, right? Given that, the future is obvious: Inside another decade, you’ll be able to get something with the specs of the mighty D3 and it’ll fit in your pocket.
My Sensitivity Problem · I’m sorry that I went for a few years without comments on the blog. I got emails of course, but not as many, and sharing them with the world was extra work.
Clearly the GR-D2 is an interesting camera; but probably not something that’ll solve my shooting-inside problem. If they’re actually out on the street in Japan and one jumps out in front of me as I walk through Shinjuku, I might give in.
For the low-light problem, there are some useful incremental steps to take. First, I could upgrade my old *ist D to a current K10D or K100D, both of which have shake reduction. The K100D is more or less exactly the same form factor and weight, which is good; the K10D adds a few pixels and weatherproofing and so on, at a fairly moderate size/weight cost.
Then, there’s a faster lens. The obvious candidates would be Pentax’s 43mm 1.9 or Sigma’s 30mm 1.4. Mind you, the Sigma is almost as heavy as the whole Pentax body. But maybe that’s OK; this is a special-purpose lens, for shooting children and colleagues, not the kind of thing you’d walk around a city with.
Finally, one could just go completely fucking nuts and pick up a D3.
