Please advise me on which model and brand to go for if I'd like to purchase a new best high end compact camera. The camera is mainly for capturing fruits, vegetables, herbs, flowers, fruit trees, plants and botanics for realistic watercolour paintings. My budget is less than £1,000. My current camera is Canon PowerShot G12. The key features and specifications I need are supermacro mode (extreme close up fine details), superzoom mode, high resolution colour and best image quality (crystal clear and ultra sharp). I'm not familiar about ISO, sensor, aperture, shutter speed etc. Many thanks.
