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 (with more than 140 characters). This time we look at Sony E Mount lens tests, the principles of depth of field clarified, Janet Delaney's new work and illegal photos of Wyoming.

  • In Sony E Mount Lens Optical Bench Tests, Roger Cicala announces a bit of a breakthrough: he's rigged up a powered Sony mount to his optical bench to be able to test the new full-frame Sony and Sony-Zeiss E-mount lenses. And this piece covers the first three: the Sony FE 35mm f1.4 ZA, the Sony FE 55mm f1.8 ZA and the Sony FE 90mm f2.8 Macro OSS. But, as Cicala points out, what you'll see in your image files is not what he sees on the optical bench.
  • Ctein has helpfully listed four old articles dealing with depth-of-field nonsense. You know it when you see it but you may not appreciate which factors most influence it. And don't bet aperture to place.
  • Alastair Gee catches up with Janet Delaney. Her South of Market images from the 1970s were shown at the de Young earlier this year and she's now back in the neighborhood with her camera. But the slide show of 18 new images don't suggest why "it just seems so much rougher than it used to seem," as she put it.
  • In WyoFile showcases potentially illegal photos of Wyoming, the publication displays images of open public land depicting resources taken after March 5 without asking permission of the public agency managing that land. The photos might be wildflowers, sunsets, landscapes, doesn't matter, they're all illegal according to Senate File 12.

More to come...
