In some ways, the company is very "stubborn," although the form factor can be considered as a hot-shoe flash product (enough portability), but the company still insists it calls photography Slim flash, so that this bumper map A1 has become the world's smallest studio flash.

It is not unreasonable that they are so attached to the A1 positioning that the new A1 flash has far higher performance than a normal hot shoe flash. According to Prism, A1's official flashback speed is only 1.2 seconds, which is four times faster than any other hot-shoe flash.

The A1 flash incorporates the standard Round Flash head from Infineon Technologies to deliver more natural and soft light, and its built-in lithium battery fully recharges (80 minutes for charging time) and supports A1 up to 350 times 75Ws full power output.

The new flash also supports the AirPort TTL system, which Prism makes so proud that it can be used with other studio flash units, such as over 9 output power adjustments, 1 / 2000s high-speed sync mode, and built-in LED plastic Light and so on.

It is no exaggeration to say that these features it has brought it closer to the performance of a professional-level flash products, rather than just a "photography gadgets for portability."
