Purpose: Shoot indoor events (e.g. seminars/workshops) with incandescent lightings at hotels.
Requirements: As silent as a compact camera, low noise at ISO1600 and acceptable up to ISO3200, at least 28-120mm equiv. focal length (whether fixed or interchangeable lens) and can shoot in RAW.
Other considerations: Can attach flash unit (+diffuser +colour gel) for group photo-taking at 5-7m range.
