This flash is much smaller than I thought it would be, and that makes me happy. It works great on my M10, and is light and well balanced on top of the camera. Everything just works automatically, it's more or less idiot-proof. Just put it on the camera, set it to TTL mode, and turn it on. It fills well in daylight and has a lot of power for bouncing off the walls etc. This flash (SF-40) and the SF-60 (which is huge) are the ONLY two options that give you high speed sync with a Leica M or SL camera. I deduct one star from my review because there is no reason this flash should cost so much; it's a flimsy piece of plastic just like any other $50 flash. I'm very frustrated that Leica has not let anyone else make third-party TTL and HSS enabled flashes for their cameras, it's a total racket. It is to the detriment of Leica owners that we have no other options than the SF-40 and the SF-60. If you don't need high speed sync, I would recommend instead getting an old used thyristor-based automatic flash for $20. They're not that hard to figure out and they give you exposures that are just as accurate as the SF-40.

I got this flash for my overpriced camera. It works perfectly. But it's a little pricey. If you have too much money and a Leica camera, this is the flash for you.

Through the lens flash. Q3 is a low light camera but if you want flash, this is great. A little large for the Q3 but it's balanced, this is only my opinion. Pricey but love Leica.

Works like it should especially for such a small unit, but is way overpriced. Made not particularly well, wonder how long will last. If it doesn’t last through a lot of use, I will be very disappointed given its outrageous price!

I took this picture on a Leica M11 monochrome in the middle of a moonless night—I was using a 50mm f/0.95 wide open with a colored glass filter that cost me 2 stops of light. I set it to TTL and this is the first shot. He’s not a professional model and was pretty hesitant to have his picture taken but when he saw how good he looked he agreed to let me do a studio shoot later.But the point is when you have time pressure and have to rely on TTL (which frankly in the last ~30 years as a photographer I haven’t used TTL since this year (2023). And I’ve been impressed with how well the TTL works.. if just *does*So for studio work I use profoto strobes—B1’s D2’s some ancient ones with raw exposed bulbs that are still awesome but when I’m on the road or doing just street photography and circumstances prevent me from using natural light, I’ve been using this. And I like it and recommend it.

Lo trovò davvero un ottimo prodotto, certo un po' costoso ma il flash funziona benissimo e già una volta aperto ci si rende conto della qualita

Compacto y potente pero el cálculo del fill flash a veces no es acertado en lodo automático. Buena rendimiento de baterías. La señal TTL tarda casi un segundo en ser enviado como ajuste de foto al flash.

Bei diesem Blitz handelt es sich um einen umgelabelten Nissin i40, der an sich schon eigentlich ein wenig zu teuer ist. Aber was soll man machen, wenn man mit Leica fotografiert, ist man ja solche Aufschläge irgendwie gewohnt. Der Blitz tut jedenfall was er soll. Trotz des Preises ist nur ein Zettelchen beigelegt, man muss sich die komplette Anleitung bei Leica vom Server laden. Zwar ist dieses Teil selbsterklärend, aber für den Einsteiger ist ein Handbuch vielleicht gar nicht so schlecht. Der SF40 leuchtet deutlich besser und gleichmäßiger aus als der SF26, kostet dafür auch ein paar Euros mehr. Vier AA-Batterien und der Schwenkkopf, sowie ausziehbare Weitwinkelstreuscheibe, Reflektor-Karte und mitgelieferter orsatz-Bouncer ("Jogurtbecher") machen diesen Blitz zu einem Allrounder.Die Leitzahl ist natürlich nur Marketing, da sie bei 105mm angegeben wird. Realistisch bei 35/50mm Brennweite kommt man da eher auf LZ 24-27. Aber das machen heute ja alle Hersteller gerne, hört sich halt besser ab, macht aber die Vergleichbarkeit schwer.
