JayceeB 28 Posted October 7, 2020 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 Share this post Link to post Share on other sites
ChrisRoss 150 Posted October 7, 2020 The WWL-1 gives a 130° diagonal field of view (equivalent to 10mm lens) from a 28mm equivalent focal length lens so that is 10/28 = 0.36x. So that makes the 14-42 into a 5-15mm equivalent lens. The WWL-1 introduces barrel distortion - sort of semi fisheye so while it gives you 130° on the diagonal, the horizontal field of view is more like 104° rather than the 121° you would expect on a 10mm rectilinear lens so that would be more like a 7-21mm lens for the horizontal field of view. Fisheye lenses are similar - while they get a 180° diagonal field of view their horizontal field of view is only about 135° Share this post Link to post Share on other sites

That's exactly what I needed on focal length. BTW Your posts have helped me immensely in my 4/3 journey 1 Share this post Link to post Share on other sites
Phil Rudin 179 Posted October 8, 2020 Regarding the difference between the Panasonic and Olympus lenses I don't think you will see much if any IQ differences behind the WWL-1. I am all for investing in the best glass you can afford but WWL-1 is going to out preform V. wide lenses behind a dome port with all M43 lenses. For significant increase in IQ with WWL-1 you would need to move to Sony full frame with the Sony FE 28mm F/2, not a zoom but the best in IQ. 1 Share this post Link to post Share on other sites
