Is the new Panasonic Lumix GX8 a game-changer?

by Ian on 16th July 2015 at 05:26 AM
Panasonic's new GX8 is packed with cutting-edge developments for Micro Four Thirds

Don't just look at the Lumix DMC-GX8 as an update to the two year old GX7, or a flat-top version of the recently released G7. I had an afternoon to try out the GX8 recently at a rather blustery Brighton and discovered why the GX8 is rather special.

So the Olympus OM-D E-M5 sensor isn't a Panasonic, but does it really matter?

by Ian on 22nd February 2012 at 04:11 PM

Olympus has found a new source of sensor for the OM-D E-M5

As I revealed on the forum earlier in this week after a tip-off from a highly trusted contact in the camera industry based in Japan, I am completely convinced that the Olympus OM-D E-M5 sensor is not made by Panasonic, so marking an end to the exclusive use of Panasonic sensors in Olympus Four Thirds and Micro Four Thirds cameras since Olympus' last Kodak

The new E-M5, GH2, GX1 and G3 and diffraction limits

by Ian on 9th February 2012 at 09:56 AM
Over at our sibling site I covered the issue of diffraction limiting digital cameras some time back. If you reduce the aperture setting in your lens beyond a certain point that relates to the pixel pitch of your camera's sensor and your images will get softer because of diffraction.

With 12.3 megapixel Four Thirds and Micro Four Thirds cameras the theoretical diffraction threshold is almost exactly f/8 although in practice I find that f/7.1 is the aperture to aim for. Users of Micro

Daily FTU hints and tips: Image Stabilisation

by Ian on 6th October 2009 at 04:00 PM
No.9: Stabilise your photography

An important innovation in recent years is image stabilisation. First developed for video cameras, image stabilisation is now a common feature in all kinds of still cameras. Image stabilisation is designed to minimise the problem of motion blur in an image caused by the movement of the camera. In other words, the system uses gyro sensors to detect movement of the camera and compensates for that movement to prevent blurring of the subject being photographed.

Daily FTU hints and tips: Olympus Supersonic Wave Drive (SWD) explained

by Ian on 2nd October 2009 at 03:46 PM
No.8: What's the fuss about SWD?

SWD stands for SuperSonic Wave Drive. It's Olympus' own technology and is used in three areas across the company's camera body and lens products.

Olympus has developed and patented several technologies that centre around the transmission of mechanical energy through high frequency vibrations. These vibrations are at so-called 'supersonic' frequencies in excess of around 25KHz, and they project wave forms through otherwise solid media,
