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 third-party wide zooms, the best f-stop, sensor pitch and arranging 19 flashes.

  • Roger Cicala performs a Third Party Ultra-Wide Lenses MTF Comparison with the Sigma 12-24mm f4, Tamron 15-30mm f2.8 and the Tokina 16-28mm f2.8. Canon and Nikon comparisons are tossed it at no extra charge.
  • People keep asking Moose Peterson, What's the Best f/stop? Moose thinks this reflects confusion about depth of field and recommends you do something about it (like his Six Pack Exercise).
  • In Resolution Improvements With Diminishing Sensor Pitch, Jim Kasson measures the difference in resolution of a good lens on a full frame camera compared to the same lens on an APS-C camera with the same pixel count. The two lenses he tests work out to a 34 and 39 percent improvement.
  • In All Together Now..., Joe McNally explains how he used 19 strobes to illuminate a barbershop quartet (which would be 4.75 strobes each). He was in Oakland's cavernous Paramount Theater.

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