The a7s – Sony’s ISO rival to the D4s
The S stands for sensitive, well not quite it stands for sensitivity. We’re talking about the S is in Sony’s latest camera release, and celebration of new technology, the a7s. In this instance Sony are using sensitivity as a precursor before the words ‘to ISO’ and not because they have boldly decided to launch the world’s first emotionally unstable camera . Believe the marketing previews and the a7s does seem to be incredibly capable when operating in low, low lighting conditions. With the a7s Sony have chosen the opposite strategy to Nikon – who released a modest boost on the D4 with their D4s- by completely re-working, rather than just tweaking, the earlier generation.
In an age of digital photography when some people talk nostalgically about film it is easy to forget that cameras used to have pinholes instead of lenses. Although only taken in 2006 the world’s largest photograph was created with the rather retro method of turning an abandoned aircraft hanger into a massive pinhole camera. The final print stands at a vast 111 x 32 feet in size meaning it is rarely on public display. However, if you find yourself in the US then head to the Smithsonian in Washington between now and December where you can catch a rare glimpse of the picture in all its glory.
