In February this year (2014) I bought the same L&M Bluefin for my new Canon G30 (as my previous Bluefin Pro with my Sony XR550 flooded). Althought the camera is quite better, the housing is a firm disillusionment. Ok it doens't fit with the camera-handgrip, but that grip was easily taken of so thta if you are a bit gentle the camera fits in without moving the infrared-cables. But more important when using the special tray for the G30 there is always vignetting (even if stabilisationsoftware is set on 'off') so we had to make a new hole to put the camera more in front, but by doing this the flip-lens couldn't work anymore. Also the 'normal' lcd-screen is a step back in comparison with the oled-screen in my former Bluefin Pro. Seems that the guys at L&M aren't quite interested anymore in making their housing-customers happy. (Although I sent in movies with the vignetting they even denied that it was possible!!) They are focussing on their lights... sadly also in this compartiment they are really doing no good. I had 2 Sola4000's ... nice lights but the charge-contacts always corroded so I needed to scrub the contacts before each charging and sometimes even put contuctive gel into the holes otherwise there was no contact between the pins and the corroded holes. Now at my last divetrip to Norway both Sola4000's flooded althought I did no deeper dives than 55m. And the lights should stand 100m according to L&M. Again all responsibility was denied as if I myself ever could be responsible for flooding my videolights (no, I really never tried to open them!). So now I'm looking for new videolights but no L&M ever again! Ok, you can have sometimes a bad product, but a bad service is something else. I hope this helps in chosing a housing.
