Do the twist
Tripod collars are great for switching between landscape and portrait (upright) orientation shooting, while maintaining good balance on a tripod or monopod.
On the move
VR or OS can’t overcome motion blur, but a manually switched or auto-sensing panning mode can still be a big benefit.
Take priority
Shutter-priority mode is ideal when you need a fast shutter speed to freeze action. Use a high ISO to avoid under-exposure.
Prime numbers
For lenses with comparable telephoto reach and the widest apertures, primes tend to be smaller and lighter than zooms, with fewer internal elements.
