Why You Should Consider Fitting A UV Filter On Your Lenses
Even though there is a long-standing debate related to whether UV filters are really necessary in the digital age, (especially given the advancements in lens / element coatings technology). As a photographer of over 25 years here at Cameracal / Breakthrough Filters UK we wholeheartedly recommend their use for the following reasons.
- Protect your lens's front element. A filter in front of a lens element ultimately protects the lens front element from damage and scratches. It is considerably cheaper to replace a filter than the front element of the lens.
- Protect your lens collar. If a lens is dropped and the filter ring is damaged this can be extracted fairly easily. If the lens filter rings suffers the same fate it is generally more expensive as modern lenses require the replacement of the whole tube / lens body
- Weather sealing. A weather sealed filter protects the lens element from dust / dirt and other elements such as water if used outdoors.
- Easier to clean. Breakthrough’s filters have nano coatings which repels dirt, water and other debris by beading up on the surface rather than absorbing and smearing
Why UV’s and not standard plain glass protectors?
Modern day Digital camera sensors do not tend to suffer from the effects of UV radiation in the same way as film emulsion, regardless, excessive UV light can still generate a blue cast when shooting with a modern digital camera. UV filters have specific coating which able to eliminate this cast and also reduce the haze in bright sunny conditions outdoors. A protector on the other hand is a plain piece of glass minus the UV eliminating coatings, its purpose as its name sake is to protect the lens only.
The use of a UV filter is particularly important if the photographer is shooting in the Jpeg format as this colour cast is often difficult to eradicate in post-production.
Is it important to use a good quality filter?
Yes, it is pointless having spent considerable amount of money on a quality lens only to fit a filter which does not match the quality of the lens optic. This would be a false economy and can result in a loss of definition and sharpness of the captured image. Lower grade filters can also reduce light captured by the sensor.
Why Use an X2 or X4 Breakthrough Filter?
The X4 series should be considered for your top quality lenses, for standard lenses the Breakthrough X2 series using top quality Japanese AGC glass will suffice. This range also have the same weather proofing and nano coatings as the X4 series.
