嗯,通常畫質會較差,尤其是寬容度...
以前剛買相機時就很納悶怎麼DSLR沒有原生iso50,結果過了四年,還是沒有

Pre-Photokina 2010: Pentax has announced the K-r, its latest mid-level DSLR. Initially sitting above the K-x in the range it offers more angular, K-7-esque styling, 6 fps continuous shooting and HD movie recording. It also regains AF-point illumination in the viewfinder. It features a high-res 920k dot (VGA) LCD display and the ability to shoot at up to ISO 25600. Unusually for a Pentax at this level it uses a rechargeable Lithium Ion battery pack but can be used with AAs via an optional adapter. We've had a chance to get to grips with the K-r and have prepared a brief hands-on article discussing its features and additions.
