This is interesting because I reached out to switcheasy support regarding the nude case for iphone 6 which is apparently 0.6mm thick

And I was told the following:
Hello,
yes, the NUDE does give protection for the camera lens.
Thank you for your support and patience so I could make it sure!

I'm hoping someone on the forums who has purchased this case will share once they receive it but I believe they just started shipping recently.
