Just Posted: Studio comparison shots from the Sony DSC-HX100V. We've just got hold of Sony's latest superzoom, the 16.2MP HX100 and shot our standard test scene with it. It's built around the latest 1/2.3" (6.17 x 4.55mm) back illuminated CMOS sensor and offers a vast 27-810mm equivalent 30x zoom. Being Sony's top-of-the-range superzoom, it features a manual control ring that can be switched between controlling zoom and or manual focus. We also have one of its main rivals - the Panasonic DMC-FZ150 in the studio and will add that to the comparison tool as soon as we can.
Technology company ICVT has developed an method to optimize JPEG compression. The company's JPEGMini system analyses each image to assess the maximum compression that can be applied to an image without loss of perceptible quality. The company says you can expect a 50-80% reduction in filesize over a JPEG that hasn't been intelligently optimized. At present the system can only be used via the company's online service. Meanwhile, the news has prompted blog PetaPixel to reiterate the little-known quirk of Photoshop's JPEG quality slider that means your images may be better saved at quality 6 than 7. (via PetaPixel)
Accessory grip maker Richard Franiec has announced he is developing a grip for the Olympus PEN Lite (E-PL3).

The anodized aluminium grip attaches to the front of the camera using industrial-grade adhesive tape and provides a hand hold very similar to the one offered by the Panasonic GF2 and GF3. The first batch of grips will be available from mid-September at a cost of $34.95 plus shipping.
