Hello there I bought the awesome Nauticam 45 degree viewfinder for my Sony A7R3 in an Ikelite housing plus the Ikelite adapter ring. Disappointingly I do not get to see the whole frame - only the centre. I contacted Nauticam about this and their answer was a shrug. At this point I am thinking of selling the viewfinder and getting the Ikelite or Inon one. Does anybody here have experience with those ? Do I get to see the image edge to edge ? In other news - a Nauticam 45 degree viewfinder will soon be for sale here. Thanks ! Sent from my iPhone using Tapatalk

Yes it is sorted ! The 330s are good otherwise - I do mostly macro so they are more than plenty Sent from my iPhone using Tapatalk

Thanks Chris! Is a test in the housing on land valid ? Or do I have to test it in the water ? Sent from my iPhone using Tapatalk

Does anybody know if a diopter lens is needed ? Can’t find it on the Ikelite lens chart. Sent from my iPhone using Tapatalk

Yes thanks for all the help ! Sent from my iPhone using Tapatalk

Just checked - does not move at all. There is also no movement when I pull on the viewfinder. Seems safe. Sent from my iPhone using Tapatalk

They are meant to be rotated - I have not really done so so far but yes absolutely can be done. Sent from my iPhone using Tapatalk

Thanks this is shot at 1/320 - will try to limit below 200 to be safe . Sent from my iPhone using Tapatalk

Ok so I mounted the viewfinder without this oring - the function of which still eludes me. Have taken it on four dives now - the housing is tight, holds the vacuum so I guess I won’t worry about it. Thanks for all the input. Sent from my iPhone using Tapatalk

Hello friends I sometimes have this issue where the upper part of the image is dark. What could this be ? It’s always a straight dark area so not sure ? Only happens underwater in the housing. Sent from my iPhone using Tapatalk

Thanks for then example - mine is perfectly round so unfortunately no luck Sent from my iPhone using Tapatalk

Yes it fits with the metal ring without the o ring. Sent from my iPhone using Tapatalk

Thanks for the reply - not sure what you mean by chord ? What’s the German word for it ? Thanks. Sent from my iPhone using Tapatalk

Yes and yes. Tried tightening it all the way but it’s missing 2-3mm, no way to squeeze it any more. I’ve now installed it without the indexing ring and o ring. I’ve done a vacuum seal on it and seems to work. Sent from my iPhone using Tapatalk
