I have a Dyron SWAL13 that I have been using with my Canon G7X in a Nauticam NA-G7X housing with the N50 short port. The relative price, wide FOV, and Blue Water Photo test results (http://www.bluewaterphotostore.com/canon-g7x-underwater-lens-tests) are what led me to the SWAL13. Thus far I have found that getting photos with razor sharp focus with this lens/camera combination is nearly impossible. The very wide field of view is great for composing big shots but many of them end up having soft focus and are barely usable. Any ideas why this might be the case? I have not had the same type of focus problem when shooting with my CMC-1 macro lens or no wet accessory lens. Here are a few example photos that I feel show this problem: https://jonjake.smugmug.com/El-Nido-2016/i-6VmGkHQ/A ( f/8, 1/40s, ISO 125) https://jonjake.smugmug.com/Cozumel-2016/i-6KVw3K4/A (f/8, 1/80s, ISO 200) https://jonjake.smugmug.com/Central-California/i-r4shgL5/A (f/8, 1/60s, ISO 200) I have read some recommendations that suggest locking focus on your fin at the beginning of a dive when shooting wide angle and others that say to put your camera in Macro mode when shooting with a wet wide angle lens. Any suggestions or tips that I can try would be greatly appreciated!

I came across a store review of the WWL-1 and an interesting piece of glass showed up there: the Dyron SWAL13. Has anyone tried this, and its narrower siblings on a m43 camera? First round I'd try it on my NA-RX100iv for 4k video shooting, as a cheap alternative to the WWL-1.

Hi all - I've taken the leap to DSLR so will be parting with my compact Canon s90 setup. I'm offering a choice of two packages plus ad-ons since it makes the most sense to sell this way.
