When shooting at slower shutter speeds it is always advisable to minimise contact with the camera. self-timer mode or a wired release are useful but limiting when composing at complex angles. A wireless remote or smartphone app offers greater versatility and functionality, providing more for your money. Many models also come equipped with intervalometers or even remote control over camera settings.
