Hoya PRO-ND 52mm 64x Neutral Density Filter, 2 Stops Product Description Size: 52mm Grade: 64x Filter Factor: 6 stops (1.8)The Hoya Pro 52mm 64x Neutral Density Filter (6 Stops (1.8)) features ACCU-ND technology that yields a truly neutral color balance that will not add any noticeable color-cast to your images. This filter is aimed at the still photography and HDSLR video markets. With metallic ACCU-ND coating on the filter, you can set your white balance once and have the same color balance even if you need to change filters due to changes in lighting, or for creative effect. The Hoya Pro ND64 52mm Filter uses Hoya's exclusive clear optical glass that has a metallic ACCU-ND coating front and back to create the neutral density affect. It is designed to reduce the amount of light entering your camera lens and should not have any other effect on the image. Reducing the amount of light allows for the use of wider apertures or slower shutter speeds for creative and dramatic effect in bright lighting conditions. It has a low-profile one piece aluminum frame. The thin frame keeps the glass secure and parallel to the sensor while allowing it to be used with super-wide angle lenses.

Hoya 72mm PROND 200 Neutral Density ND Filter 7 2/3 Stops (2.1) Product Description Exclusive Hoya ACCU-ND technology ensures accurate color balance when switching between ProND filters Filter provides ￯﾿ﾽX￯﾿ﾽ amount of neutral density stops (depending on the filter you can insert X-see press release) Manufactured from super high quality ￯﾿ﾽHoya Clear￯﾿ﾽ optical glass Assembled using a one-piece aluminum frame creating a rigid, durable, but lightweight filter Perfect for Still and Video applicationsThe PROND200 has a 7 2/3-stop light reduction equal to a ND optical density of approx. 2.1. The ACCU-ND technology in the Hoya PROND filters yields a truly neutral color balance that will not add any noticeable color-cast to your images. The Hoya PROND series is aimed at the still photography and HDSLR video markets. The series provides 10 filters from one stop to 10 stop light reduction. The Metallic ACCU-ND coating on the PROND filters do not color shift as you move from one density to the next, a common problem with other series of neutral density filters. Now you can set your white balance once and have the same color balance even if you need to change filters due to changes in lighting, or for creative effect. The PROND filters use Hoya￯﾿ﾽs exclusive clear optical glass that has a metallic ACCU-ND coating front and back to create the neutral density affect. Neutral density filters are designed to reduce the amount of light entering your camera lens and should not have any other effect on the image. Reducing the amount of light allows for the use of wider apertures or slower shutter speeds for creative and dramatic effect in bright lighting conditions. The HOYA PROND 200 is a dark neutral density filter with a filter factor of 200. This filter factor converts to a 7 2/3 stops light loss. This is a great filter for blurring motion a lot on a sunny day. Example: In daylight maybe the slowest shutter speed available with a filter is 1/60 sec￯﾿ﾽ at F/22. By adding the PROND 200 a shutter speed of 4 full seconds would be possible.

Excellent Condition Original Canon EF-S mm f/4-5.6 IS USM Lens + Hood & Lens cap. This lens retails for R, it's great bargain at R, tha's less than half the retail value. It's ideal for most canon cameras such as the 5D mark III, 7D, 6D, 70D, 750D.. The EF-S mm f/4-5.6 IS USM Lens from Canon is a lightweight, compact all-purpose standard zoom lens with a focal length equivalent to mm in the 35mm format. It is compatible with DSLR cameras that use the APS-C format and provides a versatile set of focal lengths from wide-angle to telephoto. This lens features Canon's optical Image Stabilization technology, providing up to a 3-stop compensation for image blur caused by camera shake at slow shutter speeds. A ring-type ultrasonic autofocus motor provides fast and silent autofocus action and full-time manual focus is supported even when in the AF mode. Designed specifically for digital photography, it has a 17 element, 12 group construction, including one double-sided aspherical element for reduced aberrations and crisp, high contrast corner-to-corner detail. Canon's specialized lens coatings suppress ghosting and flare and an optional dedicated lens hood can further reduce the incidence of flare. A rounded 6-blade aperture provides pleasing out-of-focus backgrounds when shooting with a shallow depth of field. Uses optics made to take full advantage of the small image circle and short back focus in EF-S lenses designed for APS-C format cameras. Image Stabilizer gives equivalent effect of a shutter speed three stops faster during hand-held shooting. Ring-type ultrasonic autofocus motor (USM) provides quiet, fast, precision auto focusing and predictive tracking. Manual focus override allows precise manual focus control even when shooting in AF mode. Aspherical lens elements minimize aberrations for high image quality at all focal lengths. Optimized lens coating minimizing flare and ghosting prone to occur with digital cameras. Circular aperture diaphragm produces brilliant out-of-focus characteristics.
