Kodak plans coating trials for 120 format Ektachrome E100 film next month

07 Jun

Kodak Alaris has given a boost to those waiting for newly resurrected Ektachrome E100 to be introduced in formats larger than 35mm with an announcement that it will be testing a new coating process at the end of next month to make roll film. The company has said in the past that the process for coating 35mm film and 120 roll and sheet films is different and that the method used to make the initial reintroduced format isn’t the same as that needed for wider formats.

Kodak Alaris said directly then that it was very likely that medium format and sheet film sizes of the color transparency film would be made available, and has since confirmed that 120 and sheet films will be made this year.

In recent posts on its Kodak Professional social media accounts, Kodak Alaris has said directly that it will be testing coating processes for 120 roll film, saying ‘We know you’re anxiously awaiting the arrival of larger format Ektachrome E100 Films. We are diligently working on bringing them to market, with a wide coating trial of the 120 format film planned for late July.’

The posts are accompanied by a picture of a girl holding a Pentax 67 medium format camera, but which was shot as part of an early trial of the 35mm format version of the film. The side of the picture is marked ‘Ektachrome 100 in 120?’

We shall have to wait and see. The company’s T-Max, Portra and Ektar emulsions are already available in sheet formats, but to special order. For more information on Kodak films see the Kodak website and the Kodak Professional Ektachrome E100 technical data sheet.

Tamron 18-270mm travel zoom lens gets slight update with fluorine coating

08 Sep
 Tamron’s new 18-270mm…  …and the previous version.

Tamron has introduced an updated version of its 18-270mm travel zoom lens, the Tamron 18-270mm F3.5-6.3 Di II VC PZD model B008TS. Unlike the previous version (model B008), the B008TS features a fluorine coating on the front lens element, in addition to the existing Broad-Band Anti Reflection coating. With the fluorine coating, Tamron says the lens element is water and oil-repellant and less likely to be harmed by dirt, fingerprints, moisture, and dust.

While the fluorine coating is the new model’s biggest change, the folks at Imaging Resource have pointed out some minor cosmetic changes, as well. The gold trim ring found on the previous lens model has been replaced with a silver ring; as well, the overall lens design has been simplified, with both the zoom ring’s and focus ring’s styles being altered. According to Tamron, these changes ‘create an external design with a high-grade feel.’

According to Tamron’s website, the new lens will launch tomorrow in Japan with Canon and Nikon mounts for ¥83,000 before tax.

Hoya uses antistatic coating to repel dust and water for new Fusion series

14 Dec

Japanese glass manufacturer Hoya says it has created a new coating that prevents dust, water and fingerprints from sticking to the surface of its filters. The company claims the coating acts like a ‘force field’ around its new Fusion series of filters, protecting them from stains as well as scratches. The idea of the coating is to make the filters easy to clean and to reduce the chance of damage while in use or storage. 

The coating is said to consist of nine layers that work to reduce reflections from the surfaces of the glass and which aim to allow as much light through to the lens as possible. Hoya says the coating has ‘virtually no effect’ on the color balance, contrast, clarity or exposure of the final image. 

The first Fusion filters will be for cutting UV, a circular polarizer and a plain protector glass. They are available in screw-in sizes from 37mm to 105mm (to 82mm in the UK) and come mounted in slim low-profile frames that are said to avoid interfering with the corners of images shot with wide angle lenses. 

Prices start from £26.99 for a 37mm protector filter. For more information visit the Hoya website. 


Press release:

Hoya introduces Fusion Filters

9 layers of Super Multi-coating make Hoya Fusion filters antistatic, waterproof, stain proof, scratch resistant and very easy to clean!

Hoya engineers have developed a new ANTISTATIC coating that acts like a force field around the filter to repel dust. Perfect for environments where dust is common, these filters require less frequent cleaning and maintenance than traditional filters. Additionally, the hardened, antistatic top-layer is water repellent, stain and scratch resistant and cleans easily when smudges or fingerprints are introduced to the surface. 

The new FUSION Antistatic professional filters are made in Japan using hand selected silicates that are carefully smelted and blended to yield high performance optical glass. Hoya then uses extreme care and precision to apply a new 9-layer Super Multi-coating formula that greatly reduces or eliminates reflections on the surface of the glass and yields very high light transmission rates. This means the filter has virtually no effect on the colour balance, contrast, or clarity of the final image. 

The filters feature a lightweight, low-profile aluminium frame to house the glass. The low-profile frame eliminates vignetting when used on ultra-wide-angle lenses. 

Fusion filters are available in UV, Circular Polariser and Protector and in sizes from 37mm through to 82mm. Prices start from £26.99 for a 37mm protector filter.

  • NEW Antistatic coating repels dust 
  • Scratch resistant – Hardened coating protects against everyday wear 
  • Stain resistant – Protects against exposure to ink, markers etc. 
  • Water repellent – Water beads up and wipes away easily 
  • Fingerprints and smudges wipe away cleanly 
  • Hoya’s Professional-grade optical glass

Tokina to launch water dispersing filter coating and IR-cut ND range

26 Feb

Japanese optical manufacturer Tokina is showing a hydrophilic filter coating that forces water droplets to spread into a thin film so that they become invisible to the camera. The coating will allow photographers to carry on shooting when rain or spray on the lens would otherwise obstruct the optical path. Read more

Non-stick glass: Nikon demonstrates new fluorine coating

Screen_Shot_2014-05-22_at_10.14.31_AM.png

Nikon’s 800mm F5.6 FL ED VR and 400mm F2.8 FL ED VR lenses earn the ‘FL’ in their names from the coating of fluorine applied to the lens elements. But what exactly is fluorine coating, and why is it important? In this video from Nikon Japan, the coating’s repellent properties are demonstrated as a variety of liquids are dripped, drawn and painted onto the lens surface. See video
