Hi,

 

 

I am thinking about buying an Omd em1. I have got an Olympus 4/3 camera at the moment and I am happy with the macro and wide angle lens I have but I am looking for something in between and was pleased to hear that Olympus were bringing out the "Pro"12-40mm but have not seen any ports for it. 

Does any one know if there will be any made?(preferably Nauticam) I am aware that the size of the lens seems to be larger so wonder if for this reason the lens won't be something usable underwater.

Can anyone suggest any other lenses that are as good in that sort of range…… I have heard mixed reviews about the 12-50 and with the Nauticam port being so expensive I am not willing to take the risk.

 

Best Wishes

Yes, Nauticam has the #36129 7" dome and a gear available now. Aquatica will have a solution using their new 7" dome as well.

 

My take on that lens is that it's not the closest focusing lens and even with a larger dome the corners may be a bit soft. However for video it may find some fans, and it is fast. I'm looking forward to Oly's new 7-14mm lens sometime this summer.

Jack:  I am hoping you have information that contradicts what I read.  My info is that the 7-14 won't be released until sometime in 2015.  I am anxious to see what that lens can do and it would be great if it were released this year.  So, have you heard news from Olympus that the lens is coming out this year instead of next?

 

By the way, everything I have read about the 12-40 is that it is a great lens.  I have just recently purchased the lens and have not really had a chance to use it much.  I have found no reviews of it for underwater use, and it may not work out well, but I find it a more interesting prospect than you do.  Basically a 12mm lens with the added ability to zoom in for fish portraits and the like.  I am planning to try it in the Zen 170 port.

The issue with the 12-40 in the ZEN Underwater 170mm optical glass port is the size of the lens and the Nauticam gear used to drive the lens zoom. The lens and gear fit the port opening but not the Nauticam extension used to extend the port away from the housing. The Nauticam 20mm extension is to short and the lens zoomed to 40mm will hit the inside of the port. I tried the lens with NO GEAR with the 30mm extension and it works but is a bit to long. I think a 25mm extension would be ideal and that is under consideration by ZEN and would require a larger inside dia. with a port lock different that the Nauticam one.

Well that's a shame.  I am not sure it is worth buying the 7" Nauticam port just for this lens, especially prior to any tests/reviews of corner sharpness with that port.  Hopefully something will be offered that will make the port work.  I am guessing the Oly 7-14 lens will be similar in size to the 12-40 and was hoping the Zen 170 might work well with both lenses.

I use the ZEN 170mm dome now with the Panasonic 7-14mm zoom and a 20mm Nauticam extension. I think this port will work well with the new Oly lens as well with a proper extension.

Hi,

 

The new 7-14mm may be of interest to me when it comes out, at the moment I have the 9-18 for WA. It is something for shooting fish portraits for anything bigger than my 60mm macro can handle I am looking for.
