Lens filters can be used to achieve a number of different jobs and can prove invaluable. Some lens manufacturers may have propriety systems in place that will only allow you to fit their filters so please check prior to making any purchases. See the below for some of the universal options available and how they can help you.

UV protection filters

are a basic need for any photographer. These can be left on the camera at all times and their basic purpose is to remove haze from your images and are also used to protect the lens of the camera from UV light that can damage the internals of the lens and also the camera. They are also handy for keeping dust out of the lens and make cleaning much easier. Also used to stop glare from light sources you cannot go without a UV protection filter. They come in all sizes:
77mm

,

,

,

.

Polarizing filters
and circular polarizing filters
can also prove to be invaluable when faced with glare and outdoor conditions. Like Polaroid sunglasses do for your eyes, these filters will block the glare from your lens so you can have crisper and cleaner images. Light rays which are reflected by any surface become polarized and polarizing filters are used to select which light rays enter your camera lens. Circular polarizing filters have the same effect, but it is important that you choose the correct version for your camera. They allow you to remove unwanted reflections from non-metallic surfaces such as water, glass, etc. They also enable colors to become more saturated and appear clearer, with better contrast. Also available in a range of sizes: 77mm, 72mm, 67mm, 62mm, 58mm, 55mm, 52mm, 46mm
.

Warming filters
as advised by the manufacturer improve skin tones and are ideal for portraits taken on a cloudy day or outdoors, in shade on a sunny day. This filter will also absorb the blue light cast by electronic flash to achieve warmer and more realistic skin tones. Available sizes:
77mm

,
72mm

,
67mm
