Vivitar 90mmf/2.5 Series I macro (1 img)
May 8, 2012

This is a night blooming cactus flower that blooms around midnight and is gone in a day or two. I took this before sunrise and had to put the white balance on open shade because the only light was the blue sky. I think that it was f/5.6 for a couple of seconds.

I was one of the designers of this lens but have not had one for a while now. when I got one on Ebay recently I was shocked to see that one of the rear spacers was very shiny and was causing some flare. I took out the last element and the offending spacer and painted the spacer with some very flat black paint. Much better!
