I have to say that the lens itself would have nothing to do with how you describe your images being recorded. It's a manual lens. The f-stop and focus are not going to change after you set them. There are no data connections from the lens to the camera. I've read a few people having problems with the Go 4 app and manual lenses and would suggest, that is where the problem lies. As with virtually everything in life, lenses are a compromise in multiple ways. Getting one down to 150g with the glass required for an f2 wide angle means you have to sacrifice elsewhere and obviously the electronics are the only area that doesn't effect the final quality of the images. A minor inconvenience when you consider the option is to not have anything with that FOV available at all.
I'm well aware this is a manual lens. However, it should focus to infinity shouldn't you agree?
Mine suffered from poor quality control and even the infinity mark was a quarter inch off to the right giving me some room to 'maybe focus to infinity,' but it failed there too. I even took the Venus Optics support person to task on it as well when I was asking about "It's issues, and their 3 year warranty matter."
Another interesting find I discovered with this lens was if you watch the GO 4 histogram while you change the camera settings, and being that it is a manual unchipped lens, it might take 20-30 seconds for the histogram and exposure to settle out. Seems the X5S camera of mine hunts for proper exposure not knowing what lens is mounted and if I hit the shutter too soon or late, the exposure is way off on stills which I primarily do.
Congratulations if you got a good one and it focuses correctly, but I tend to be very picky on this stuff and mine went back. Maybe if they improve on it I'll try it again as the focal length does show promise, but if it will not focus right on distance (infinity) or it stops before it gets there, it's junk to me.
