    Last week I installed the Peau 3.97mm f/2.8 lens on my CGO3+. During normal daylight conditions the photo's are very sharp (better than the standard lens). But when taking a photo facing the sunset, the corners of the photo turn light. I took this photo with a Polar Pro ND4 filter (ISO 100, exposure 1/160, auto white balance).

    Anyone experiencing similar issues?

    I'm thinking that its the Polar pro filter causing vignetting.

    Sadly I am also experiencing it without the polar pro filter.

    Well that totally sucks. Give Peau a email with the photo. They are pretty good at responding. I have dealt with them with other cameras and they have been very helpful. Expensive but helpful LOL

    Vignetting should make the affected area darker, not lighter. Also, the Peau lens has a more narrow FOV, so the Polar Pro filter is less likely to exhibit vignetting with that lens.

    My guess is that light is reflecting off the lens barrel or shroud.

    Anyone knows a firm in The Netherlands (or Europe) which offers focussing aftermarket lenses on the CGO3+?
    I know Peau does it, but then I need to send it to the US.

    You are right. I just re-focussed the lens. It was focused for objects too close.

    I re-focussed on further distance. The images are realy sharp now.:)

    Can you post an example please? I bought the same lens and have yet to install it. I want to know that it is a worthy upgrade. Thanks!

    This is a photo after I re-focussed the lens. Same place, about the same conditions. Without ND filter.

    The problems in the corners is still present (although less) when shooting in photo modus. When I take a picture in video modus the corners are just fine).

    I have returned my Peau 3.97 lens. I tried to contact Peau several times over the last 4 weeks for help but they never replied to my emails.
    Carlolina Dronz (where I bought the lens) also tried to contact Peau, but they even didn't reply to them.

    When I installed the original CGO3+ lens, i did not have any issues in the corners. So it must have been an issue with the lens.

    They are well aware that there are consistency issues with the sharpness and focus on the edges of their lenses and supposedly trying to find a better way to have them made.
