Nauticam Macro to Wideangle Lens 1 (MWL-1) for Full Frame

There is a fairly indepth review on Bluewater Photo of the new Kraken/Weefine WFL-09s which seems to be a similar design. It has a shot of the same anemone at different apertures which is quite interesting. Generally it seems that you keep the reduced DoF from the macro lens, so stopping down is required for depth of field more than for corner sharpness (although both go hand in hand). This allows for an interesting look. I felt the Bokeh was quite busy though...

I've also received some test shots from Marco at Uwcamerastore.com that he shot with the Olympus 30mm macro. Sharpness across the frame was very good at f20 or so. At f8 I felt the depth of field was already quite shallow, so the MFT depth of field advantage seems to be smaller than I personally expected. Interestingly the Bokeh on the Olympus lens was much nicer than on the Nikon in the Bluewater review. The lens is also compatible with the Olympus 12-50mm zoom and (according to their compatibility chart) even with the 12-45mm PRO zoom. 

I think it could still be a perfect one lens solution for dives that you don't know what will happen and also for close focus macro, but I'm not convinved, yet. 

I have been using the MWL with Nikon Z7 and a f 60mm lens.  I do need to stop down to at least f/16.  It's a beast to carry, but properly floated underwater, is easy enough.  Benefit is you can get right to the dome port for  CFWA shots.
