We’ve been taking a look at Fujifilm’s recently released firmware update for the X10, which was designed to reduce the much-discussed ‘white orbs’ blooming effect. Our initial conclusions are disappointing enough for us to pre-empt our forthcoming coverage of the issue with a quick update on our findings so far. Sadly, all the indications from our studio and real-world shooting so far are that the update appears to have very little effect on the appearance or intensity of these artefacts.

A week after posting a firmware update for its G-system cameras, Panasonic has announced firmware updates for its DMC-G3 and GF3 Micro Four Thirds cameras. Version 1.2 improves compatibility of both cameras with Four Thirds lenses when mounted via the DMW-MA1 adapter. The updates are available for immediate download from Panasonic’s website.
Sony has released firmware v1.03 for its SLT-A77 and A65 cameras. Currently only available via the company’s Asia site (the first region in which the cameras are widely available), the upgrade promises to improve the responsiveness of the control dials and function buttons, along with the speed of switching between EVF and LCD modes. It also adds support for the HVL-MT24AM macro flash accessory.
Ricoh has announced it will update the firmware of its GRD III enthusiast compact camera. The update, due in mid October, is the fifth feature-adding revision for the high-end model and includes several additional features that have come from its GXR and GRD IV cameras. These include the ability to assign an additional option to the ‘Adj.’ lever and the locking of the power button if the optional new GL-1 metal lens cap is fitted. The company says this will be the final update for the GRD III.
