Ricoh has updated the 2006-vintage Pentax 10-17mm F3. 5-4. 5 fisheye lens with new coatings and a more modern exterior. The lens, now known as the HD-Pentax DA fisheye 10-17mm F3. 5-4.
5 ED, is equivalent to 15-25. 5mm when mounted on APS-C bodies for which it's designed. It has the same optics and screw-drive AF system as the original model, with the main change being the addition of HD and SP (Super Protective) coatings. The appearance of the lens has been updated to fit newer Pentax bodies, and it now features a removable hood.
The 10-17mm has 10 elements (including ED glass), a six-blade aperture, minimum focus distance of 14cm (5. 5") and a 180° angle-of-view at its wide end. This compact lens is just 80mm (2. 8") long and it weighs in at 317g (11. 2oz).
You'll be able to pick up the HD-Pentax DA fisheye 10-17mm F3. 5-4. 5 ED later this month for $499.
Press Release
Ricoh announces redesigned fish-eye zoom lens for K-mount digital SLR cameras
New HD PENTAX-DA FISH-EYE 10-17mm F3. 5-4. 5ED features the latest HD coating for enhanced image quality and completely redesigned body
WEST CALDWELL, NJ, July 9, 2019 Ricoh Imaging Americas Corporation today announced the launch of the HD PENTAX-DA FISH-EYE 10-17mm F3. 5-4. 5 ED zoom lens for use with K-mount digital SLR cameras. The compact and lightweight fish-eye lens features the latest HD coating and a completely redesigned body.
The lens provides a 180-degree diagonal angle view in the APS-C format at a focal length of 10mm to deliver eye-catching fish-eye to ultra-wide-angle images. It has a minimum focusing distance of 14 centimeters, allowing photographers to be as close as approximately 2. 5 centimeters from the front end of the lens to the subject for ultra-close-up photography. It also features a Quick-Shift Focus System which provides an instant shift to manual-focus operation after locking a subject in focus during autofocus operation.
This lens is an upgrade based on the currently available smc PENTAX-DA FISH-EYE 10-17mm F3. 5-4. 5ED (IF). A high-grade, multi-layer HD Coating has been applied to the optical elements of the lens, enabling the capture of high-contrast images with edge-to-edge sharpness and minimizing flare and ghost images. A SP (Super Protective) Coating, highly repellent to water, grease and dirt, has also been applied to the lens’ front surface, making it easy to wipe off any stains or fingerprints.
The exterior of the lens has been redesigned to match the design of the latest PENTAX K-mount digital SLR models, and also to make its lens hood removable. When mounted on a PENTAX K-1 or PENTAX K-1 Mark II camera body, the photographer can remove the lens hood to produce nearly circular fish-eye images, expanding the range for photographic expressions.
