I ended yesterday’s post with this: In order to pick the right mass, spring stiffness, and damping to minimize camera movement in response to shutter movement, we have to know something about the forcing function created by the shutter movement, and also about the range of shutter speeds that are important. Today I’m going to… [Read More]
Petitioning Sony about a7R shutter shock
Lloyd Chambers just posted this on his blog. While I agree with Mr. Chambers that shutter-induced vibration is a problem, I don’t think this is the best way for the photographic community to deal with it. I don’t think the argumentative tone of the petition in general, and the demand that Sony publicly call their… [Read More]
On vibration control, part 2
Before we go any farther, I’d like to deal with an assumption that I’ve been making all along. It’s not a conjecture that I’m comfortable with. The only reason that I’ve been holding on to it is that, if it’s not true, there’s not much we can do with a tripod to control the shutter… [Read More]
On vibration control
When I was working at Hewlett-Packard in the early 70s, I remember walking through optical labs and noticing the benches the engineers used to set up experiments. The most striking thing was the top: a huge slab of four or six-inch thick dark-gray granite pockmarked with holes on a regular grid. The bench had many… [Read More]
Looking back – and forward
I’m starting to take stock of the last couple of months’ work that I’ve done on this blog. In October and November, two things hit me at about the same time. They were interrelated and complementary, so I pursued both. The first was the challenge of making sharper pictures for the firehouse series. That led… [Read More]
