What is the difference between the MBP-3 and the Plate for Canon C100/300/500?

The Mini Bridge Plate MBP-3 was designed as a universal base plate, fitting to as many cameras as possible through specific adapter plates.

The Plate for Canon C100/300/500 was designed specifically for the Canon C100/300/500 cameras.The length of the plate fits exactly the base of the camera and the plate is compatible with BP-12 and BP-13 studio bridge plates, as well as BP-8 and BP-9 with the Bridge Plate Adapter BPA-2 included in any Plate for Canon C100/300/500 set.

6. Support for Sony PXW-FS7
If you can read this, you have to activate javascript for your browser. This extension was brought to you by TYPO3-Macher, die TYPO3-Agentur.
The FS7 has a handle, a handgrip and a built-in shoulder pad. Why do I need accessories from ARRI PCA?

ARRI PCA accessories help third-party cameras blend in to a high-end camera rental environment. Strong base plates and handles are designed to sustain PL or EF lens configurations, and the system is directly compatible with studio bridge plates such as the ARRI BP-8 or BP-9. Furthermore, the ARRI shoulder pad is a heavy-duty upgrade designed to remain comfortable even with a studio bridge plate attached.

The ARRI AMIRA features an adjustable base plate that helps balance the camera on the shoulder. Why can't the ARRI PCA for Sony FS7 benefit from the same feature?

The ARRI AMIRA camera body is designed around its sliding base plate and remains solid under load. The Sony FS7 is a lightweight camera with a short base that has not been designed to sustain the stress of a sliding base plate, so flexing of the rods could occur. The ARRI PCA for FS7 includes a strong, camera-specific base plate that ensures rods do not flex under heavy use.

Does that place the shoulder pad too far back and will this affect the balance on my shoulder?

With the Extension Unit XDCA-FS7 and a V-lock battery, we find the FS7 with a short PL zoom (e.g. ARRI ALURA 15.5-45) balances well on the shoulder.

The ARRI PCA CCH-2 handle is offered as an upgrade to the original Sony handle. If I choose this option, do I lose the wireless microphone and GPS functions of the Sony handle?

The ARRI Top Plate for FS7 and CCH-2 handle do not support GPS or wireless microphone. These functions are seldom used on film sets. The CCH-2 handle and top plate are designed to sustain the abuse of a substantial PL-configured camera rig with the third-party accessories typically encountered on film set, such as wireless lens systems, wireless transmitters, ultrasonic measure devices, etc.

Is the Lens Adapter Support LAS-1 an optional extra?

The LAS-1 features in every PCA set for FS7. Unless native E-mount lenses are used, a lens adapter will have to be fitted (e.g. E-mount to PL, E-mount to EF, Metabones Speedbooster, etc.) and physically supported. The LAS-1 offers support for most third-party lens adapters that feature a 1/4-20” thread at the bottom (ID/E, 16/9 inc, Metabones, etc.)

So I can use the FS7 as a B-camera on film sets with a long PL zoom attached, such as the ARRI ALURA 45-250, and a studio matte box such as the ARRI SMB-1?

This is perfectly possible, as the ARRI PCA for FS7 offers direct compatibility with studio bridge plate configurations and the LAS-1 supports the necessary third-party E-mount to PL lens adapter.
