  1. Yes we are scanning the net Metabones Smart Adapter is expensive. it's a shame for the MC-11. We thought that having lens and adapter of the same company was the best choice...
  2. I'll let you know. Probably latest camera/ring fw update broken the lens compatibility. He will change the adapter first. Now our priority is having a working camera Then we will check for image quality. We have several extension rings and a underwave/igloo cristal dome so we could swap to Canon 8-15mm if quality is not adequate.
  3. I copy and paste my previous message in a proper thread that could be very useful for future users. I'm helping my buddy with a Sony A7RIV + Sigma 15mm-MC-11 combo. The camera become completely unstable. It switches itself between AFS and AFC. Occasionally it focuses or the screen goes black. The aperture does not work. We initially tried with original fw and then updated camera and ring to the latest fw version The sigma manual explains that if the ring led is off, the lens is not compatible and Sigma does not list the 15mm as a compatible lens but I trusted the many users here in the forum. Given the so many references here for this lens, any suggestion? At this point we will try the Metabones smart adapter V asap. Is there some reason not to chose the Meta Smart Adapter IV over the V? Thank you all
  4. I'm helping my buddy with a Sony A7RIV + Sigma 15mm-MC-11 combo. No luck, so far. The camera is like crazy. It switches itself between AFS and AFC. Occasionally it focuses or the screen goes black. The aperture does not work. We initially tried with original fw and then updated camera and ring to the latest fw version The sigma manual explains that if the ring led is off, the lens is not compatible and Sigma does not list the 15mm as a compatible lens but I trusted the many users here in the forum. End of sad story
  5. Hahahaha I'm not usually fussy and I'm happy but those corners looked good to me, That's why I didn't understand Maybe I have a couple of clips that can show the very slight fisheye distortion introduced by the WWL-1 and the incredible quality of corners compared to a straight, dome lens. A few car wrecks. Panasonic 14-42 @14mm, F5.6, ISO 1000 I had to get so close (too close) because the ambient brightness @60 meters was so strong that my keldans couldn't light the wreck well. You can see the slight fisheye distortion in the center on the side of the car. But at the corners, objects coming out of the frame and the sand are almost perfect. I challenge getting these results with a dome at F5.6.
  6. All my latest video are shot with WWL-1B and I rarely use it wide open. It's slightly fisheye and it doesn't deform shapes too much. A quick example here where there are mostly divers which retains normal proportion
  7. I do not know him personally. I have seen his videos on FB through some mutual friends. You can try to contact him on FB and ask him for information. https://m.facebook.com/enrico.rabboni It is good to know that other manufacturers also make ports compatible with WWL-1. I hoped Aquatica would also make one but so far no news....
  8. It's strange that Isotta was not able to give you a WWL-1 port directly from the factory. As far I know there is at least another guy with a GH5 Isotta housing and a WWL-1 port produced directly from Isotta. He is Enrico Rabboni, who won several prizes at the last Madeira Underwater European Contest with this setup.
  9. Hi Phil, I'm asking because the Canon 15mm is not listed on the metabones specs. Another option would be the Sigma 15mm with its adapter...
  10. Hi all, I'm going crazy trying to figure out which adapter ring I should buy for this old lens. I read that the metabones Smart Adapter Mark V is good for lenses from 2009 onward. Any suggestions? Feedback on AF?
  11. The problem with Rock Boots is that they are very large so sometimes even a Scubapro jetfin doesn't fit in. A turtle fin could help.
  12. I think nobody maybe except Nauticam tried the 12-35 mm on a WACP. Too expensive for a test
  13. We all like to have new toys and hope for a linear advancement of technology over the years. Actually, it's hard to admit, after so many years, the GH5 (GH5S and MKII) are still the top for underwater video shooting in that price range and more. Despite the years, you will only have a clear improvement by changing to models that have RAW but, as you can easily verify, the economic investment is double if not triple. I am talking exclusively about video. Photography is a whole other story. Too often we mix the topics when talking about lenses and features. Currently for my video needs the only real impediment I find is regarding the lens to use with the WWL-1. While for other formats and brands there are choices, for MFT we are at a dead end with the 14-42 that is just a piece of plastic.
  14. My buddy has a GH5S and we film together every week. At low ISO (up to 1250) there's a small difference. Higher than that, GH5S is better but I would miss IBIS. I'm able to film nearly steady shots at 42mm (84mm). On a GH5S it's nearly impossible except you are half diver and half gimbal (like my buddy).
  15. Any difference between Canon 15 mm and Sigma 15 mm fisheye on a FF Sony A7RIV?
  16. GH5M2s are like unicorns. I had found a used one but the seller did not show up for the meeting and disappeared. If you eventually decide to sell it keep me in mind. IMHO the top camera for video right now is the C70. Secondly the R5C. they both have RAW light and Canon for underwater color is unbeatable. the problem is the total cost which makes them (for me) unaffordable.
  17. I made this from the day one and I still do not receive email. I do this work for a living, but as usual you don't like to be challenged and react in an unhinged way. No problem.
  18. No you can't or just partially because the cable length and bulkhead position are chosen with that design in mind
  19. After one month still not getting notification from the forum because I have a Google account. Don't you suspect that the problem is you and not Google?
