I have a 650-2ch and have recently noticed blurred image on the right side of the footage. Abit like the RGB is out of sync and causes blurry image. After reviewing the very first footage I saved from the dashcam, I notice it's on that footage too.
I suspected it might be the windscreen glass but I recently changed vehicles (same make and model but 5 years newer) and front cam is in a slightly different position and blurry image is still present. I've cleaned the lens so that's not the cause either. I've seen footage from someone else's 650 and theirs has the same blurry image on the right side of the footage.
So we're on the same page, I'm not talking about blurry like streaking motion-effect blurry image, but like it's out of focus on part of the image.
I was thinking of trying to find a "test pattern" image or webpage to see how it compares (ie: take a still shot of the footage and compare to the original); does anyone know of such a website which might have some kind of test images to "calibrate" or compare accuracy of lenses? Perhaps a photography/still camera website?
Here's a link to one of my clips so you can see what I mean.
This is probably a good example because vehicle is stationary and you can easily compare the detail in the trees to the left compared to the lack of clarity in the trees to the right, and even the red traffic lights.
