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”.
