Im glad others have had better luck then ive had with bower, and watching videos shows better quality then I expected. When i have shot with borrowed bower it just felt cheap to me, had horrible flaring and sharpness issues, and overall just felt like a cheap product. For video it seems like some problems can be avoided, but most people with a HDSLR shoot photos too. It seems quality is being more and more overlooked when it comes to lenses, my rule of thumb as a beginner photographer/videographer is "buy nice so you dont buy twice". Bower doesnt fit into that for me.
