FAQ

Q: I have ALPA lenses with Copal 0 Shutters. Where can I order X-Shutters to exchange the Copal 0 shutters by myself.

A: Today's high-performance optics are not designed to exchange shutters freely. For a conversion to X-Shutter, your lenses need to be sent-in to ALPA. For a conversion, the lens gets disassembled, thoroughly cleaned and the X-Shutter will be mounted. The lens will then be checked and adjusted with a sophisticated MTF measuring unit to ensure the highest possible image quality.Most of these works are carried out in a clean room environment. You will get back a squeaky clean, as-good-as-new lens with a brand new X-Shutter. Your ALPA dealer will gladly take care of the shipment and customs declaration for the shipment to ALPA.

Q: I’m totally fine with setting shutter speed, aperture and more for the X-Shutter on theIQ4-150 screen. When it comes to trigger the image on my ALPA, I do not want to touch the back or camera. I have a cable release from ALPA, however, the plug on the IQ is now occupied by the X-Shutter connection cable.

‍

A: We are planning to announce a new cable release with probably some additional functions, apart from triggering the camera, soon. In the meantime, were commend that you remote control the IQ4-150 with your iOS device and the app Cascable. The app allows you to fully remote control the IQ4-150 via direct WiFi connection. Cascable triggers the camera without noticeable delay and offers a ton of other features in addition, including a secure and fast connection with a tethered Ethernet cable to your iOS device. To learn more, download the Cascable manual.

Q: The technical data claims that the fastest shutter speed of the X-Shutter is1/1000s. Sometimes, I need faster shutter speeds. Is this possible?

A: Thanks to the Electronic Shutter, shutter speeds of up to 1/4000s are possible. If you choose a shutter speed above 1/1000s, the X-Shutter will automatically open its blades and the IQ4-150 will use the built-in electronic shutter. Note that rolling shutter effects may apply and using flash is limited.
