For years Iâve used the Fuji Finepix F10 which took really great pictures with 5Mpixels but most importantly was fast enough to take ISO 400 photos. That camera still works really well but is not pretty big. Ideally you want a shirt pocket camera that: 8MP sensor and lense quality so you can get A3+ ISO 400 quality so you can use available light most of the time Image stabilizer to future help you get those low light shots Aperture and shutter priority to control exposure Shirt pocket size
