Kase Filters launches newholder The new generation K9 holder makes filter use even easier and suits lenses as wide as 14mmon full-frame cameras

Hahnemuhle: back to nature

Hahnemuhle’s production site is located at the edge of a nature reserve, and the company is committed to environmentally friendly paper production using Its latest three Natural Line fine-art printing papers take this even further and use bamboo, hemp and agave to provide the cellulose for paper production. These fast-growing plants needminimal maintenance, no pesticides and less water, all of which helps to save resources and protect the environment. Bamboo is made from 90% bamboo fibre and has a smooth surface texture with a warm tone, while Hemp is made from 60% hemp fibre and 40% cotton, and this also has a smooth matt surface texture but with a white tone. Agave is 70% agave fibre and 30% cotton, and has a rough surface texture. All three of these papers are free from optical brightening agents. These Natural Line matt papers are available in sheet sizes A4 to A2 and in roll sizes, too. Generic ICC profiles for popular fine-art printers are available for free from the website . • precious natural resources sparingly and responsibly.

diameter, and this – together with redesigned filter holder rails – means the system can be used on lenses as wide as 14mm on full-frame without the drawback of vignetting. Handling of the lightweight aviation- grade aluminium alloy holder has also been enhanced, with an improved polariser drive cog, modified cut-outs to enable easier polariser removal, and a rapid-turn screw fastening. Stephen Elliott, Kase UK’s technical director, said: “The last K8 generation holder was excellent, but we knewwe could do even better with the K9. It is

KASE FILTER’S SOLUTION to using a polariser in combination with other filters is an elegant and very effective one. Rather than placing a large polariser at the end of the lens in front of other NDs and graduate filters, the new system uses a magnetically attaching polariser sat next to the lens front, and then up to three other filters can be added. An ingenious rear cog drive is provided to allow quick and simple polariser adjustment. The new K9 holder uses the same polariser mounting system, but this filter is now larger, with a 90mm

The new K9 holder is available to buy now fromKase’s website and at the company’s UK official stockist, Wex Photo Video. The K9 holder kit costs £140, and the price includes the holder, slimline circular polariser and four rings: the 77mm and 82mm geared lens adapter rings, plus the 67mm and 72mm step-up rings. •

exactly what we think a filter holder should be: simple to use, practical, reliable and with no gimmicks. The fact that our designers and engineers have managed to make these improvements and make the new holder even lighter just proves what an innovative team we have. Our main goal for the K9 was to allow it to be used with ultra wide- angle lenses without compromise.”

A telephoto zoom and three primes fromTamron

All four lenses feature a moisture-resistant construction, fluorine front element lens coating for easy cleaning of smudges and fingerprints, and a 67mm filter thread. Prices are yet to be announced, but the lenses are due to hit shelves between this December and spring 2020, with the primes launching a fewmonths before the zoom. For details, see the website for Intro2020 – the company is acting as Tamron’s UK distributors until 30 November 2020. We’ll have details of Tamron’s new distributor in the next issue of PN . •

lengths each have an f/2.8 maximum aperture and are designed for full- frame Sony E-Mount mirrorless systems. The new zoom features Tamron’s newly developed VXD linear motor focus mechanism, which promises accurate, fast and quiet AF, and supports a range of camera-specific features including hybrid and eye AF. Focus capabilities for the three primes that users will enjoy include a close focusing distance (11cm, 12cm and 15cm for the 20mm, 24mm and 35mm respectively) and a magnification ratio of 1:2 – a first in this category of lens.

Tamron has announced the third model in its series of f/2.8 high- speed zoom lenses, the 70-180mm, in addition to three primes. The 70-180mm, 20mm, 24mm and 35mm focal
