The new Professional HS Freeze 4 Studio Flash Unit from Rollei is an ideal supplement to the HS Freeze 6 model especially for challenging outdoor shoots that take up a large amount of room but can also be used very well on its own as a main flash device that is handy and mobile. Its lower total weight of around 1 kg and its more compact measurements make it ideal for photo safaris, where every gramme counts but where you wouldn’t like to do without flash output of 400 Ws or the creative flash modes such as HSS or freeze either. The replaceable, rechargeable lithium polymer battery, which is available separately, requires just 1.7 seconds to make its complete flash power available again and supplies 500 bursts when it is fully charged.

Professional reflector and 5 colour foils already included in the scope of delivery

Because of the sturdy Bowens connection you can use all of Rollei’s professional flash equipment and any other compatible accessories with the Rollei HS Freeze 4. The scope of delivery already includes a reflector that can be obtained separately and which you can connect in no time at all with the enclosed magnetic colour foils. An integrated infrared sensor facilitates the uncomplicated IR slave operation. The integrated radio receiver has a range of up to 300 metres and can be controlled directly with all Rollei professional radio transmitters. Combine several HS Freeze 4 devices for specific light scenarios or incorporate the HS Freeze 6 device directly with it also.

Creativity and flexibility in the studio and in the open air

The long-lasting, high-performance rechargeable battery with 14.8V/4.4 ah makes you completely independent of mains connections and tangled cables. Naturally, you can use the HS Freeze 4 in the studio as well but it displays its superior capabilities especially in the open air or in difficult spaces. 500 flash bursts are already sufficient for a great many flash ideas. Simply take several charged batteries with you for more comprehensive projects. High-quality electronics ensure that the charging voltage lasts for an amazingly long time. In combination with the radio transmitters that are available for the most prevalent camera models you can take shots with flash completely wirelessly in the TTL, manual, Easy Cap or delay modes, synchronize on the 1st or 2nd shutter and achieve a flash duration of up to 1/19,000sec.
