The Leica SF 40 Flash

The Leica SF 40 is a hybrid flash and continuous light source for Leica cameras. Key features include:

Output and Operation. The Leica SF 40 Flash covers a 24-105mm (full-frame) zoom range, which you can expand to 16mm with the wide panel pullout. It has a flash output of GN:131’ @ ISO 100/105mm and GN:89’ @ ISO 100/35mm. Two rear dials make it easy to adjust power settings and quickly switch modes. Manual power control allows you to adjust from full 1/1 to 1/256 power, or to adjust exposure-compensation ranges from -2 to +2 EV in half-step increments.

Continuous LED Source. The Leica SF 40 features a built-in continuous 5600K LED light that has 9 levels of output intensity and is well-suited for video work. This dual-source feature makes your light source as versatile as your camera, allowing for mixed-media (stills and video) coverage for wedding, documentary, and photojournalism work.

Versatility. Bounce the light off walls, the ceiling, or any which way you want to angle it with the SF 40’s 90° of tilt and full 360° of rotation. An integrated autofocus-assist beam helps you nail sharp images quickly and accurately. This flash is powered via four AA batteries (not included), which will give you roughly 220 full-power flashes with a recycle time varying from 0.1-4 seconds based on power level.

Are we out of stock?

If you don't see exactly what you're looking for and that makes you sad, please give us a shout. We might have good news for you. Here's a link to our contact form.

We offer a 3-day inspection period on all sales, during which time you may return the item for a refund of the purchase price, not including shipping.

On this item, we include a LensAuthority 90-day limited warranty. This warranty covers damage that arises from normal use of the item. It does NOT cover accidental or intentional damage. More details are available in our FAQ section.

In addition to the standard 90-day warranty, you may have the option to purchase an extended warranty. If we're able to offer an extended warranty on this item, you'll see a checkbox to add that warranty - see the area just above the "Add to Cart" button.

If you select the extended warranty, you'll get additional protection from Consumer Priority Service ("CPS"). The CPS warranty will take effect after our 90-day warranty ends. However, the CPS warranty term would begin on the date of purchase. For example, if you buy an item with a 2-year extended warranty today, your coverage would end two years from today.
