HCIdiver Posted July 27 Share Posted July 27 (edited) I was watching alex excellent video on a1 Sony settings and he mentioned using SteadyShot Adjust Manual mode when using the 28-60 lens with the wwl-b1 wet lens. He suggested to dial in the focal length in this scenario. Quick kudos for the smart ones on here that know how i can find this out please? Is it 14mm or more or less? Weather is bad here so im tweaking.... Edited July 27 by HCIdiver Link to comment Share on other sites More sharing options...
HCIdiver Posted July 27 Author Share Posted July 27 OK. Did a bit of googling... and found a post on this site from @Architeuthis here: Based on this I am guessing the answer to my question is 13mm! REplies below if im wrong... Link to comment Share on other sites More sharing options...

Let‘s say it is diagonal. The according focal length at 130 deg could be around 10-11mm if used on land. For 70 deg it is around 30mm 1 Link to comment Share on other sites More sharing options...
Chris Ross Posted July 27 Share Posted July 27 The WWL is a 130° field on the diagonal axis however it is stretched significantly more in the corners due to the barrel distortion. The horizontal field works out to be about that of a 13-14mm full frame lens. It is equivalent to a 10mm or so rectilinear lens only on the diagonal. I would think using the horizontal field which has a slightly magnified image scale as input to the stabilisation routines would probably be the best bet as it is the effective focal length for most of your subject. 1 Link to comment Share on other sites More sharing options...
