They have this watermark size now and i guess they didn't change that cam (same on cam 1 and cam 3)
Sorry for the next big amount of pics
I can give some examples of bad/pretty old cams used at a&a houses and affiliates and other managers that replace them by new models would improve the image. Probably some of them have at least the same age that VH
I can dig if they probably could have some specifications that make them good to be use in close zoom when compared with others.. But the quality/definition is worse then other cams from same division
