The exterior of the remote switch is identical to the pixels remote release for Panasonic cameras (wired remote release for Panasonic Lumix DMC FZ100 FZ50 FZ30 FZ-20 L1 LC10 LC1 G1 GH1 GH2 GF1 G10 DMW-RS1 / RS1E / RSL1 & Leica DIGILUX 2, 3 similar to RM -RS1), only the connector is now of course Canon-specific. I had already gathered quite good experiences with the Panasonic counterpart and had therefore to grab any concerns, even with Canon at a cheap product instead of the original accessories. The price-performance ratio is excellent, the workmanship is good and the handling succeeded precisely how it should be.
