More than 80 million How many interchangeable lenses are there in the market now? 200 pcs. for AF film SLR camera 49 pcs. for D-SLR camera Four Thirds Canon EF Nikon F SONY α Mount Mount Mount Mount Lens Panasonic Canon Nikon SONY Manufacture Olympus (Sigma, (Sigma, (Sigma, Tamron, Tamron, Tamron, Sigma Tokina) Tokina) Tokina) Lens Nothing 30 million 35 million 16 million Property (Minolta from Analog lens) era The total 23 57+ (69) 59 19+ (48) number of (AF50+MF9) lens + (66) Digital 23 (All lenses 5 (EF- 7 6+(6) dedicated lens are designed S)+(13) (DX)+(13) for D-SLR) 4/3 system has the largest lens amount dedicated for D-SLR.

Film camera lens size is big, especially tele photo lens is too big to carry. Thanks to smaller image circle, lens size is smaller. Problem 2. Image sensor cannot receive oblique angle light caused by film camera lens sufficiently, so the image quality is deteriorated. Improved telecentricity causes more sharpness even periphery of the images. Problem 3. Reflection from image sensor is re-reflected at lens surface, so ghost and flare are easy to occur in digital camera. Optimized coating prevents ghost and flare Even someone has enough lens property for film camera, those lenses do not provide expected perfect quality. So the lenses developed specially for D-SLR are necessary and this is the advantage of 4/3 system. WhyWhy diddid PanasonicPanasonic adoptadopt FourFour ThirdsThirds system?system?

Winning in high-priced D-SLR market is indispensable to get the enough profit by DSC business in the future. 2. By the success of D-SLR, we can build a strong position as camera brand and it has good influence on the compact camera market as well. Year of 2010 : Target Sales Quantity - 11 millionmillion unitsunits Positioning of L1 among LUMIX 1. L1 is the first D-SLR for LUMIX and our flagship model. 2. The most important objective of this L1 is increasing LUMIX brand image. 3. We need to build up our LUMIX D-SLR image with L1 to make a success in the entry-level D-SLR market next year. Target user Person who has range-finder camera such as traditional Leica M series. Person who wants to have different products from others. Person who wants to have more emotional camera.
