No it doesn't fit the A58. Bought it thinking it would fit but was sadly disappointed. The only shutter release I have found is the Sony Master Commander remote. They are in very short supply - mine is coming into the country on 10th April for delivery to the Sony shop on 11th April.

I do not know anything about Pixel RC-201/S1 shutter cable and sony alpha a3000 with mini USB. Sorry your hand book should tell you what you need to know and if you go on the web and investigate what batteries are compatible with your camera. David.

Always read the manual so you can identify which accessories can be fitted to the camera and where. Page 15 of the manual identifies item 32 on the DMC-FZ200 diagram as the MIC/REMOTE socket. This is where the remote control is connected to. It takes its power from the camera and on my FZ200 it works very well.

Not familiar with the 7D MK2 I use this with a 6D. If your camera has a small headphone like socket, then no. If it's a larger, metal socket and you can see 3 pins in it then yes. Someone more knowledgable may come along :)
