Look at ZEEK video
Magic Lantern RAW Monitor | FEELWORLD F570 WORKS w/ No Pink/Dropped Frames MV1080 |
Thanks. Like I said in my first post, I started with Zeek's videos - and then reading the comments I found that the information in the video (not this one) was obsolete but that the video hadn't been updated. So as an information source, problematic. But if you say this one is still relevant, that's great.
Edited to add: having just talked about this with Zeek on youtube, I'd really caution anyone against using him as an information source. He doesn't get that just posting "External monitors work fine with the EOS M" is problematic when they only work with lower quality modes, as long as he's happy with those modes. A nice guy, but what he posts can be misleading because it's incomplete. Or it's obsolete and no longer the case at all, but he keeps the video up anyway.
