RUMOR: A7IV still unofficially targeted for end October…but still unsure…

The A7IV is going through the same painful story of the ZV-E10 release. The worldwide chip shortage makes it impossible to have release schedule. Anyway so far the A7IV should still be announced by end of October but I have been told that we still can’t be 100% sure of that.

What’s definitely likely is that the A7IV will ship out in December but not in majestic quantities. Depending on the demand some of you might have to wait til AFTER Christmas to get it.

Those are the rumored Sigma 18-50mm F2.8 DC DN Contemporary lens specs

Probably next week Sigma will announce the new 18-50mm F2.8 DC DN Contemporary lens. Here are the specs:

13 elements in 10 groups
minimum shooting distance 12.1cm (wide angle) / 30cm (telephoto)
maximum shooting magnification 1: 2.8 (wide angle) / 1: 5 (telephoto)
filter diameter 55mm
size φ65.4 × 74.5mm (E-mount version φ61.6×76.5mm)
weight 290g.

RUMOR: Sony A7IV has 15 stops of DR

The A7IV tentative announcement is still scheduled for mid-end October. But it might be slightly postponed if the worldwide sensor production shortage doesn’t improve a bit. In the meantime I can share that the newly developed 33MP sensor combined with a new processor will allow to squeeze out 15 stops of dynamic range. At least that’s Sony marketing saying this. We have to see in real world test if this is a correct claim.

Sony A7IV rumored specs:

  • launch in October (if chip supply permits this)
  • Newly developed 33MP sensor
  • 15 stops of DR
  • 4k30 video is oversampled from 7K
  • 5.5 stops of IBIS (+ AS)
  • Same A7sIII body design
  • Full size HDMi
  • UHS-II SD-cards and CF Xpress cards
