New Sony camera sensor could bring HDR video to cell phones
Sony Exmor RS sensor upgrades photo and video quality of smartphone cameras.
I am skeptical of the HDR movie recording claim vis a vis cell phones. HDR video recording likely produces very large video files, not exactly the best match to the limited memory on smart phones. However, the HDR output might have benefits to at least improving dynamic range of the MPEG4 recording. Present small sensors generally have terrible dynamic range.
Clever way to program a DSLR – by putting the code outside the camera
Inexpensive dongle interfaces between iPhone and certain Olympus and Panasonic DSLR cameras. A software app on the iPhone adds new features including time lapse, motion detection, high dynamic range controls, and other capabilities.
Does it work? E-M5 iPhone controller… | 43 Rumors.
Which camera company will be first to offer their own software development kit for a camera?
Panasonic | 12.5mm f/12 Lumix 3D G Lens for Micro Four Thirds Mount Cameras – $49.99
Panasonic | 12.5mm f/12 Lumix 3D G Lens for Micro Four Thirds Mount Cameras | HFT012.
The $249 lens is currently being sold with a $200 rebate offer, so your cost is $49.99. I just ordered one.
Officially, the little lens does not support video in 3D, but that is supposed to be easy to work around – just put tape over the electrical contacts on the 3D lens and use the feature in the camera (see menus) to use the camera without a lens. The effect of all this is to recorded side by side (left-right) video for the left-right eyes.
The lens is wide at 12.5mm (25mm full frame equivalent) and slow (f/12) but all that is fine for deep depth of field 3D. The main issue is that the lenses are very close together, which is only going to be useful for relatively close in subjects. However, since I currently used paired cameras with a roughly 3″ and 6″ interaxial distance, I figure the narrow interaxial on the 3D lens will be useful for very close in subjects. Looking forward to trying this for 3D video!
User installable apps might be coming to cameras
I have promoted the idea that modern cameras should provide software development kits and make what some hackers have done (CHDK for Canon or VK’s PTool hack for the Lumix cameras) a supportable feature. At the 2012 CES, I spoke with each of the camera manufacturers (except Olympus) about this idea. Only one was real receptive to the idea and one was emphatic “Will never happen”. But now comes this item:
3) Olympus: apps on cameras are coming. In that case Mr. Thackara said: “It’s something that has been discussed, but because the emphasis is on image quality, they’re [Olympus] a little wary of opening up the OS. I think it’ll happen eventually, but things are not as easy as we think. The appeal of people being able to add to their cameras is big though. It’s on the list.”
