how good is the Oly 9-18 or the 12-50 in the Nauticam 4" dome port?

14 June 2015 - 08:14 PM

Hi guys!

 

I've got a trip coming up in late July to the Sea of Cortez on the Rocio Del Mar. Expected sightings underwater include sea lions (100% possibility), whale sharks (80-95% possibility), sharks (60-100% depending on species) and dolphins, humpback and sperm whales, and mobula rays (40-60% possibility). 

 

I'm using a Olympus e-m5 in a Nauticam housing with an 8mm Panny fisheye and the 12-50 Oly lens in the dedicated port. Lighting is from two YS-01 strobes. I also own the 9-18 mm Oly lens.

 

My question is, "should I spring for the 4" dome port at this late date? Realizing that I can use the 9-18 and the 12-50 in that port is pretty good, but I won't have any time to practice with it before the trip and the cost ($480 not counting the zoom gears) will definitely cut into my trip funds. Without the zoom gears, I would be stuck with whatever setting I put the lens at before encasing it in the port, but in the 12-50 case, the 12mm setting might be pretty good. I am not sure how sharp either of these two lenses are underwater. Above water, I find the 12-50 to be quite sharp. I've only owned the 9-18 for a little while, but I don't use it too much as most of it's range is covered by the 12-40 PRO lens (used exclusively above water).

 

Would either of these possibilities be worth the cost at this time? 

 

Thanks for your help!

 

 


Color Negative Film?

05 August 2014 - 07:00 AM

Hi Guys!

 

  I'm going to Cozumel in January. I've been there many times before and this trip is just for a relaxing, fun vacation. Underwater photography is not my first priority on this trip so the Nauticam housing and the OMD-EM5 is staying home. I'm taking my Niknonos V with a wide angle lens and a closeup framer. 

 

  My problem is that since transparency film has gotten so expensive and hard to find processing for, I'm going to be using color neg film. Does anyone have suggestions on what brand and type of film to use? I'm leaning towards Kodak Ektar 100 since it is easy to get and has a 100 iso. 

 

  Thanks!
