A fantastic CPL, best value on amazon at current price discount
on 30 August 2009
I bought this HD Circular Polariser (CPL) after having used the Hoya range over the past few years and being extremely pleased with the brand overall (quality, build, polarizing effect and ease of being able to screw on and off)
Overall, I prefere the Hoya range over many other makes and brands and find them to create a deep polarizing effect (to increase saturation of colours, skies, bring out clouds and reduce reflections).
However, with the exisiting range of most brands of CPLs, they are commonly known to reduce the amoung of light entering the sensor by between 1-2 stops of light (in other words, they amount of light hitting the sensor is reduced by half to a quarter of the amount without the polarizer attached).
This means that longer shutter speeds are necessary (great if you can hold the camera steady for blurring water, or on a tripod, not so great if you are handholding your shots).
This CPL is a new HD filter, which allows around 90% of the light to hit your sensor while keeping the polarizing effect the same. This means that you can maintain higher shutter speeds and stil get a great effect.
This enables me to keep the CPL on at all times (except for indoor shots and low light shots)
This CPL is not to be confused with the pro-1 range (which still reduces the amount of light like the regular CPL; the only difference with this being the that the pro-1 range is a very thin filter, thereby reducing vignetting at very wide angles.
I highly recommend this CPL and Amazon has one of the best prices around (currently deeply discounted)..
