Canon EF 85mm f/1.2 L Service Journey Part Two

Ginseng

For the second time in as many months I have sent off my favorite lens (which is possibly going to lose that distinction thanks to my 24-70 f/2.8 L that I just picked up) to the Canon Factory Service Center. My first experience with Canon Factory Service was actually a really good one, as they hastily repaired my shutter mechanism and had the camera back to me within a few weeks.

A few months later I decided to send them my Speedlite 580EX which had a faulty motor in the zoom mechanism which allows the flash to automatically change the size of the flash that is thrown to suit your current lens, zoom level and sensor size. At the same time I sent them my 85 1.2, which was, and still is, having problems focusing.

When I focus on an object that is 10 feet away, I get the focus confirmation light, but then the resulting image is focused a few feet past where it should have been. With nearly any other lens, this would not be a problem at all, but thanks to the razor think depth of field at f/1.2, this problem makes my lens nearly useless at the aperture that it is designed for.

After holding my lens for nearly 2 months, Canon Factor Service returned it to me, with no changes whatsoever, saying that it was restored to factory quality. I am hoping for Canon that the problem was with their tech, and that factory quality does not mean that the focus is off by nearly 20%. I am eagerly awaiting the functional return of one of my favorite lenses.

Triforium Control Center

Eric Richardson and I have been trying for over a year to get in to the Triforium Control Center in the Los Angeles Underground Mall. Today Eric got us a tour thanks to help from Councilmember Jan Perry and Greg Fischer, who were both instrumental in the re-lighting of the divisive public work of art originally lit 1975.

Even now the Triforium has been drawing praise and scorn, most recently from the City Attorney's office which has been claiming that the music is disturbing them and has requested it only play from 11am to 1pm, which completely defeats the purpose of having the lights on, as you can hardly see them during the day. Although many art critics despise the sculpture I find it strangely charming and the primitive computer control system intrigues me.

When we looked through the control center today we found an old Teletype machine that was used to read and write punch tape which held the program the Triforium's computer used to synchronize with music. Our goal is to take those tapes, capture them and use them as a basis for the new computer control, which will most likely be a BASIC stamp or a PIC microcontroller. Once that works the next step, would ideally be to have some type of web interface to the system.

I brought my portable studio lighting setup along for the tour and took some photos, of which here is a sampling:

5 Things You Didn't Know About Me

Well, I've been too busy to blog recently due to several large projects that I'm working on concurrently, but I figured I would respond to this 5 things meme, as Siel of Green LA Girl tagged me.

  1. I lived in South Africa for a year when I was 6 years old.
  2. I only drink coffee on ice (and some times it's not even fair trade!)
  3. I make my cats dance, but I think they like it.
  4. My first job out of High School was designing rave flyers.
  5. I want to retire in Santa Fe, New Mexico.

I am tagging: Peneloper, Eric, Celia, Jim and Ed.
