To the users of AF-S NIKKOR 500mm f / 5.6E PF ED VR
Hello, this is Teppei in charge of new products of KoPro.
As we announced in a previous blog, today's topic is the development completion of the Stray Light Reduction kit for the HB-84 lens hood which is used for 500mm f / 5.6E PF ED VR.
The Specifications of the HB-84 kit
Today's introduction is for the lens hood stray light reduction kit specifically made to fit the AF-S NIKKOR 500mm f/5.6E PF ED VR, which is Nikon's latest telephoto lens. This kit is made of Fineshut SP0.2 like the others and it too provides the same anti-Stray light performance just like a lens hood with a Flocking finish.
I'll be going over the comparison of the light reflection against the incoming light as usual. By the FineShut anti-Stray light effect, our kit can give better light absorption performance than untreated lens hoods.
This lens hood is for 500mm lens, so it’s quite big! It has Φ120mm and length is around 80mm. Since the inner surface area of the lens hood is quite large, in case of backlighting, the effect of stray light may be bigger compared to wide-angle lenses.
Although this is a simple and slight improvement in optical performance, repeating such slight improvements will eventually lead to a big difference of image quality. These customizations are recommended to users who are particular to the image quality.
Attaching three pieces of the same seal can make one inner circle. If you buy the kit, one extra seal is packed together. The counterbore in the lower side of the seal is to avoid the lock on/off button on the lens hood. Basically, the counterbore is necessary for only one seal, but since the root position is almost hidden, so we judged the counterbore issue could be ignored. So, we decided to make all three shapes the same.
Because the sticking area is large, and the inner surface of the lens hood is rough with anti-Stray light paint, we recommend you to use around 10% high density detergent water for smooth sticking. Because of high density detergent, a lot of bubbling may appear during the sticking process, so after you have completed positioning or drying, we recommend washing the surface and the lens hood body with tap water to rinse it off. It will wash off excess detergent.
Because this product uses a lot of materials, the price is around JPY3,600. Considering the price of a lens hood to be around JPY5,000, you may feel our kit is a little expensive. We are very sorry for this, however this is due to the high material costs.
I think, because of the characteristics of the 500mm lens, they are often used in harsh backlight environments, such as when taking bird photos or airplane photos. When we read the reviews for 500mm lens, we sometimes see a few negative comments in regards to the decrease in contrast due to the backlight. So, we believe our stray light reduction kit can contribute to the improvement of optical performance for this lens hood.
About the next notice, we are currently developing a kit for AF-S NIKKOR 58mm f / 1.4G lens hood, HB-68, which became a hot topic in next-generation optical design.
We are planning to design for Fujifilm and Sony standard lenses. If you have any other requests or comments, please let us know. We are waiting for your request!
