andycorleone Posted September 24, 2017 Share Posted September 24, 2017 Hi, Do I need any sort of adapter to attach a Rectilux Hardcore DNA to a Kowa 8z 16H? Link to comment Share on other sites More sharing options...
Tito Ferradans Posted September 25, 2017 Share Posted September 25, 2017 No. The Rectilux's screws can go right on the front bit of these Kowas. Link to comment Share on other sites More sharing options...
Dude_ger Posted September 25, 2017 Share Posted September 25, 2017 Hi Tito, do you know how wide you can go with the Hardcore DNA on a 8z? Of course tried your calculator, but somehow it tells me vignetting with 35mm which i don t have on the gh5 with Kowa 8z... Thanks bro Link to comment Share on other sites More sharing options...

Thanks bro The GH5 rules are still broken on the calculator, but you can work out the math based on this weekend's video reviewing the Kowas. The vignetting tests were done using full frame, so you can go backwards with crop! :D Link to comment Share on other sites More sharing options...

Julien416 Posted September 26, 2017 Share Posted September 26, 2017 Careful, the HDNA brings a lot of additionnal vignetting. Typically i could go as wide as 50mm on FF with my 8z. With the HDNA it's more around 70/75mm. Link to comment Share on other sites More sharing options...
Dude_ger Posted September 26, 2017 Share Posted September 26, 2017 Okay so the 35mm on GH5 should be okay Link to comment Share on other sites More sharing options...

Hi, thanks for sharing the information. However, do you feel comfortable tilting down with the HardcoreDNA simply screwed onto the Kowa 16H/8Z? Is using just the provided screws absolutely secure? I am afraid the Rectilux will unscrew and fall to the ground but maybe I am overreacting. Thought about buying an HTN adapter. Cheers. valery akos 1 Link to comment Share on other sites More sharing options...
Grimor Posted July 2, 2018 Share Posted July 2, 2018 Just received my HTN ring v2 for the Kowa 16H and can confirm it is the best way to attach the rectilux. Rock solid and zero extra vignetting Thanks to HuuTuan from Vietnam for his product and service and @Tito Ferradans for the advice.
