The SF 60 flash unit and the C1 remote control unit have been designed to complement the Leica S, SL and M systems. They can also be used with the Q and CL. The flash offers an extensive range of options in a compact form while the remote enables off-camera flash in conjunction with the SF 60 to enhance creative opportunities.
The flash has compact dimensions and a low weight of 300g but brings many professional features, including TTL-flash, HSS to 1/8000s, a flash-head with tilt and swivel function, a zoom reflector, an integrated diffuser and reflector card, and master/slave capability. It also offers an impressive guide number of 60 (at ISO 100). According to Leica, this makes the SF 60 an extremely powerful and versatile mobile solution for qualitatively excellent light-management in any situation.
The SF 60 also features constant LED light output adjustable in nine steps as a source of light for spontaneous video recording of subjects in low light. All settings are made with two dials and the colour LCD panel of the flash unit.
The SF 60 is powered by four AA batteries but for longer shooting sessions it can be connected to an external Power Pack which, because of its higher capacity, enables even faster recycle times and simultaneous power supply of up to two SF units. The Power Pack can also charge USB devices such as smartphones or tablets.
The SF C1 remote control unit adds many creative options. Mounted on the hot-shoe of the camera, it enables wireless remote control of SF 60 units using the 2.4-GHz frequency band. Flash units can be organised in up to seven channels, each with three groups, and controlled either together or separately with the same or different settings. The unit also features a colour LCD panel to view or change settings.
Both units are now available from authorised Leica UK stores and dealers. The SF 60 flash unit costs £450, including VAT, and the SF C1 remote control is £250.

The SF 60 Instruction Manual download states that there is a GN table for the various zoomed lens focal lengths on the inside back cover … but the inside back cover is not included in the downloads. Potential buyers could be assisted if the GN table was included so we can all see the actual guide numbers applicable to the various focal lengths. GNs would usually increase with longer focal lengths and decrease with shorter (wide angle) focal lengths. Also, would help if the GN was stated properly i.e. in Meters or Feet … in the USA, Imperial ‘Feet’ is still in common usage. We can assume the GN is in 60m (i.e. meters) but at what focal length? I’ve known manufacturers to overstate their GNs by quoting the nominal GN for a longer focal length rather than e.g. a 50mm standard lens. And sometimes in the past some manufacturers have overstated GNs for the UK and American markets by stating same for ‘Feet’ rather than ‘Metres’. When spending hard earned €£$ on expensive flashguns consumers need to know all the facts before parting with their money. If those facts are not in the instruction manuals then dealers might be hard pushed to explain same to customers … assuming dealers know and understand exactly what a GN is.
