In this recurring column, we highlight a few items we've run across that don't merit a full story of their own but are interesting enough to bring to your attention. This time we look at welders, wide-angle MTF results, Blow Up and the Pentax HD 28-105mm WR.

  • Ming Thein indulges his obsession with Welders. "How often do you see somebody focusing intently on what is essentially a continuously powered, almost unidirectional flash?" he asks. Sometimes highlights should be blown.
  • Roger Cicala and team report MTF results for the Sony 24mm f1.4 GM, Sony 35mm f1.8 and Tamron 35mm f1.4 SP. He was surprised. "For the last two years or so, we've been seeing among a number of lens makers some amazing jumps in image quality," he writes.
  • Jim Kasson tries Exposure Software's Blow Up to smart resize images.
  • Kirk Tuck takes his Pentax HD 28-105mm WR Lens for a stroll. He set it at f8 with ISO 100, adjusting ISO only when the shutter speed couldn't be handheld. And was quite pleased with the results after profile correction in Lightroom.

More to come! Meanwhile, please support our efforts...
