28mm F1.4 Kamlan and 7Artisans lenses
  • 11 Replies sorted by
  • SainSonic, manufacturers of the Kamlan 50mm f/1.1 lens, are releasing a new 28mm f/1.4 manual focus lens, which will be available on KickStarter - starting from the 1st June, with an estimated delivery date of August 2018, and a starting price of $149 US.

    When used on APS-C mirrorless cameras, the lens gives an equivalent of 42mm (Fuji X, Sony E), 44.8mm (Canon EF-M), and when used on Micro Four Thirds, the lens gives and equivalent of 56mm. A range of sample photos taken with the lens can be found on Flickr.

    Kamlan 28mm f/1.4 Lens Features:

    • Superior optical quality
    • Low chromatic aberration
    • 11 circular aperture blades
    • 8 elements, in 7 groups
    • 6 High Refractive Index elements
    • 25cm close focus distance, 0.15x magnification
    • 344/384g weight
    • 52mm filter thread

    Thanks for help. For list look how I formatted it.

    The Kamlan 28mm f/1.4 sports an all metal and glass design with a premium feel that belies its inexpensive price tag. The manual aperture ring is declicked, allowing videographers to make smooth aperture changes while retaining traditional aperture stop markers for stills photographers. The manual focus ring is incredibly smooth and perfectly damped, allowing for smooth and accurate focus results across the 160 degrees of focus travel. The quality of the focus and aperture rings is that of a premium lens.

    The lens has a metal 52mm front filter thread, and the lens hood is included to allow for shading from the sun along with protection for the lens. The lens is well corrected for chromatic aberrations, allowing for minimal color fringing even at very wide apertures.

    We have designed a new premium metallic lens hood for the New Kamlan 28mm F1.4, which employs a threaded connection for a firm, easy to use connection. The lens hood has built in filter threads to allow for the use of filters even with the hood attached […]

    One of the key strengths of the Kamland 28mm f/1.4 is its high degree of color accuracy and richness. Unlike some competing lenses, it does not introduce too much color cast to images but instead delivers a neutral, accurate color rendition even wide open, that will be useful to both stills photographers and video users as well.

    The lens utilizes high quality optical glass with higher levels of refraction to help shape light more efficiently and to produce lower chromatic aberrations. Chromatic aberrations are noticeably more controlled than on competing lenses.

    In real-world shooting there are minimal chromatic aberrations on the Kamlan 28mm f/1.4, and what aberrations do exist are easily corrected.

  • @VK the focus and iris grips - are they FF gears? Kamlan also make a 50 & 55 lens. Would be nice to have more focal lengths... (14, 25, 80 etc)

    • 13 aperture blades
    • 11 lenses in 9 groups (1 aspheric, 2 ED lenses, 3 high refraction and low dispersion lenses)
