Sony Alpha A33 and A55 Official: First Translucent Mirror DSLRs

The rumors that have been circulating in recent weeks were spot on: Sony has just announced four new DSLR cameras: the A33, A55, A560, and A580. As expected, the A33 and A55 are the world’s first pellicle mirror DSLRs, and have the features and specs we posted just yesterday: phase-detect autofocus while recording HD video or shooting 7fps or 10fps respectively.

Alleged Photo of the First DSLR Pellicle Mirror on the Sony A33

The above is supposedly a leaked photo of the not-yet-announced Sony A33 and its pellicle mirror, the first of its kind on a DSLR. Rumor has it that the camera will officially be announced early tomorrow morning.

SonyAlphaRumors received a tip that Sony will be using the following arguments promoting the new pellicle system:

  • Minimal shutter lag: Mirror does not move, and therefore results in shutter lag of less than 0.1 seconds
  • Auto focus: First DSLR to offer phase detection autofocus during HD video recording
  • Frames per second: No moving mirror allows camera to reach 10 FPS
  • No mirror blackouts: Optical view and Live view will remain uninterrupted during shooting
  • Compact design: Eliminating the moving mirror system reduces weight by 25% and size by 20%

Stay tuned. Official news about the A33 and A55 should arrive shortly.


Update: Amateur Photographer just published a post titled, “New Sony Alpha 55 and Alpha 33 EVF DSLRs to feature fixed Translucent Mirror“. Almost as soon as it was published it was taken down (darn those easy-to-click “Publish” buttons!). Here’s a quote from the now-removed article:

Sony is set to introduce shooting speeds of up to 10fps, as well as video, in its latest Alpha DSLR cameras, the Alpha 55 and Alpha 33, by using a new non-moving ‘translucent’ mirror. Echoing the technology of the pellicle mirror in Canon’s EOS RT of 1989, Sony’s new semi-transparent mirror allows light to be fed simultaneously to a camera’s imaging sensor and AF system, removing the need for a moving mirror and providing the potential for much improved focus tracking as well as active AF in Live View and video modes.

Looks like this is no longer a “rumor”.

Photos of the Upcoming Sony A33 and A55 DSLRs Leaked

Alleged photographs of the upcoming Sony Alpha A33 and A55 DSLR cameras have popped up in an overseas forum. The images look legitimate, though the A55 and A33 front views are identical images that had the model number Photoshopped. Not sure why that is.

These two cameras are rumored to be pellicle mirror cameras. Read this post that we wrote last week to learn more about what pellicle mirrors are.
