It’s important that you pick the right optic for the type of photographs you’re taking
Are you looking to replace the lens bundled with the camera for something better – by which we mean an optic delivering sharper and brighter results? There are a staggering amount of choices out there, and it can be a little overwhelming making a decision. Ultimately, the smaller the lens’s ‘f’ number, the greater the amount of light that’s let into your shots.
For example, an f2 lens will be brighter – sometimes referred to as ‘faster’ – than an f11 lens. Also bear in mind that a ‘prime’ or standard lens, with a fixed focal length of, say, 50mm, will typically give sharper, more detailed results than a jack-of-alltrades zoom with a focal length of, say, 28-70mm.
