The Hoya 55mm PROND EX 1000 is a screw-in neutral density filter with an optical density of 3.0, cutting the light reaching the sensor by 10 stops (1/1000). It lets photographers use long exposures to smooth water and blur moving clouds or crowds in daylight, and lets filmmakers keep a shutter speed that matches their frame rate, or shoot at a wide aperture for shallow depth of field, in bright light.
Hoya's ACCU-ND metallic coating is designed to give a neutral colour balance, avoiding the colour cast that cheaper ND filters can produce, including in the infrared part of the spectrum.
Fits lenses with a 55mm filter thread.
I had great experience, very fast dispatch, much cheaper than others, nothing to complain about, would definitely consider A1 again when I need to buy more tech
Brand new phone box sealed get scared little bit because label on box southeast Asia SIM card only but phone is unlocked works with UK SIM card straight away so just ignore all good price low is well
After researching products, I found that A1 Tech Deals offered the iPhone I preferred at a fantastic price. My new iPhone arrived on time, by registered mail. I would highly recommend them.
Really good prices- was skeptical that there would be hidden costs afterwards, but they delivered everything I ordered on time and for the price advertised.
The website was easy to use. My order was despatched next day and arrived as promised.
My query regarding the product was answered quickly and thoroughly.
