Panasonic has continued to improve the
firmware. The v. 2.1 firmware claims improved performance, a 20% improvement in autofocus speed, and new features such as a 1:1
aspect ratio and focus resume. On July 30, 2010, Panasonic released another firmware update for the LX3. The stated reason behind the update is 'Optimization of software processing', with an additional comment stating 'Change in software version has no effect on camera performance'. Panasonic launched the successor to the LX3, the
LX5, on 21 July 2010. The latest model features a revised sensor, longer zoom range and improved control layout without fundamentally changing the existing model's formula. It offers a more flexible 24–90 mm equivalent lens with a bright f/2.0–3.3 maximum aperture range and a comparatively large 10MP sensor in a small body. The body itself is barely changed compared to the LX3 – gaining an improved hand grip, clickable control dial, direct movie record button and a 1:1 position on the aspect ratio slider. Most significantly it gains a connector to add the DMW-LVF1 electronic viewfinder originally launched with the GF1. Other than this, the LX5 gains the AVCHD Lite format for its 720p video, and its image stabilization is branded with the company's latest 'Power O.I.S' designation.[http://dpreview.com/news/1007/10072110panasonicdmclx5.asp ==See also==
