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 camera announcements, Canon camera announcements, the Fujifilm X-T1's focus tracking performance and posterization from Sony's Raw file compression.

  • Sony has announced its a6000 mirrorless with a 24.3-Mp sensor, 11 fps capture, 0.06-second autofocusing and built-in WiFi. Body only for $650 or $800 with the 16-50mm motorized kit zoom lens, the a6000 will ship in April. Sony also announced two Cyber-shot superzooms.
  • In addition to a $550 entry-level Rebel T5, a $330 waterproof PowerShot D30 and a $350 30x PowerShot SX700 HS compact superzoom, Canon announced its $800 large sensor, compact G1 X Mark II.
  • Dan Bailey tested the Fujifilm X-T1 has surprisingly good tracking performance. Using a Fujifilm XF 55-200mm lens, he tested a subject moving away from the cameif. Then, with an XF 14mm f2.8, he tested a subject switching directions. Finally, with the 55-200mm again, he tested erratic movement with a defined background (a bird in flight). "The X-T1 will track moving subjects," he concludes, "and it will do it under a variety of conditions, light levels and lens choices."
  • In Sony's 11+7-bit Delta Compression Posterization in Some Situations, Lloyd Chambers reports, "Alex Tutabalin of RawDigger has posted an essay on the posterization effects that can be observed with Sony ARW Raw files due to the 7-bit delta compression."
