    Rectangular Softbox

    85 x 110cm


    Interfit By Karlu Photographic 

    The new Interfit range of fifteen professional quality softboxes are manufactured from the very best materials.

    The internal rods are made from strong flexible carbon steel or duralumin, the fabrics are made from a specially treated polyester and ”heat resistant up to 400c / 752f”. The highly reflective silver base, produces an even edge to edge distribution of light. Air vents have been positioned on the top and bottom to allow air to circulate when in use.

    The boxes also feature Velcro on the outside edge to support Interfit Pro accessories such as masks etc.

    A strong webbing is in place to securely hold the rods in to place. The two layers of high quality diffusion are non fluorescent. With both diffusers in place a maximum light loss of only 1.2 f-stops is achieved. Four shapes of box are available with a range of sizes for each shape. The Interfit Pro Soft Box range is designed to fit onto the majority of studio flash units and each box is supplied with a choice from one of the thirteen speed rings and a soft case.

    When ordering, choose your speedring from the drop down list below.
