Thanks for the quick response, Mr. Ross. That's exactly what I needed on focal length. BTW Your posts have helped me immensely in my 4/3 journey

Folks, I'm wondering what the equivalent focal length range would be with a Lumix G Vario 14-42 II + Nauticam WWL-1. What wide angle lens focal length would 14mm reduce to? What telephoto lens focal length would 42 reduce to?. Also, from the forums, it sounds like the Lumix G Vario 14-42 II is the best IQ of the Olympus and Panasonic choices (I'm shooting with the Oly E-M1 II). Do I have that correct? I already have an Olympus 14-42 IIR that came as a kit lens, and am wondering if an upgrade to the Panasonic 14-42 is worthwhile if moving to a 14-42 + WWL-1 option. Thanks for any responses you may have, -Jaycee

I tested the 14-42 with the 6" dome in a test tank. No vignetting. I'll try this in the wild and see how it works. Thanks, Chris, for your suggestion.

Thanks, Chris. I'll test out the 6" dome in my test tank. Also, I was so focused on the highly recommended 12-40 that I didn't consider the 12-35mm option. Will look further at that, since the 7-14 and 12-35 share a common port. If the tradeoffs in autofocus and image quality are acceptable, might be worth considering.

Thanks for your reply, tursiops. I have a 30mm macro which I use for fish portraits and a 60mm macro which i use for nudis. This is why i have both the 45mm port and 20mm extension. 45mm port for the 30mm lens. 45mm+20mm extension for the 60mm lens. I don't plan on investing much in the 14-42 kit, but I already have the lens. Was trying to see if i could utilize my existing ports and extension. I actually tried this out in a tub today with the lens set at 14mm with the 45mm+20mm extension. Although the 65mm is longer than required, there was no vignetting at the wide end of this lens, so I think it will work if I just purchase the zoom gear. There may be other optics factors at play here, but it appears to work. The situation i'm trying to gear up for is a local dive with resident tigers. Sometimes the sharks approach very closely, but other times further away. This is why i would like a more flexible zoom range than my current wide angle 7-14 setup gives me. Eventually I would like to add the 12-40 and port, but this is a pricey option. Also, sounds like Olympus has an 8-25mm F4 Pro in their future roadmap (if that ever gets fullfilled), which would be a nice combination.

Thanks for the feedback. I don't plan on purchasing a port for this lens, just wondering if i could use it with one of my existing port combinations temporarily, until I can afford a 12-40 + port. So all i would be purchasing is a zoom gear.

Folks, I own a kit lens that I would like to use as a mid-range zoom, mainly for ambient light, big animal photography : Olympus M.Zuiko Digital 14-42mm f/3.5-5.6 II R I would like to avoid purchasing a dedicated port for this lens. 36136 (macro port 56) Instead, I'm wondering if I could get by using one of the following Nauticam ports that I already own, and just purchasing the zoom gear: 36135 (macro port 45) + 36620 (mini extension ring 20) - Used for Oly 60mm macro. 36133 (6" dome) - Used for Panasonic 7-14. 36132 (4.33" dome) - Used for Panasonic 8mm. (** Could add the 36620 mini extension ring 20 if required). Does anyone have experience trying any of these combinations? Thanks.

Thanks, Tim, Chris and Interceptor for your advice. One more related question i'd like to add to this thread. Recommendation between: Olympus 8mm fisheye + Zen 100mm dome + Mini Extension Ring 30= $2130 vs 30mm Macro + Nauticam MWL-1 = $2130 (assuming you already have the 30mm lens + port)

I am putting together a parts list for a Olympus OM-D E-M1 Mk II + Nauticam system, and was hoping to get some recommendations on the following lens choices.Fisheye:Panasonic Lumix G Fisheye 8mm f/3.5orOlympus M.Zuiko Digital ED 8mm f/1.8 Fisheye PROThere isn't a big difference in price, but the Olympus is much larger. Is the quality of the Olympus noticeably superior to justify the size and extra $200? Also, I believe the Olympus lens must be removed to extract the camera from the housing, which is slightly inconvenient.Medium Macro:Panasonic Lumix G Macro 30mm f/2.8orOlympus M.Zuiko Digital ED 30mm f/3.5 MacroSame price. Is one recommended over another for auto-focus and quality?

Hello fellow UW Photographers. For me, spending time underwater is a gift most folks will never experience first hand. Underwater photography is a way to share that experience with others and raise awareness of the beauty and diversity of life found in our oceans. I enjoy the art and science of photography and hope to improve my skills with practice and learning from others. Looking forward to participating in the wetpixel forums
