Yes, VR adds to battery usage and consequently helps use up a charge quicker.
My question is why you continually disparage VR and IS and OS? You seem generally very knowledgeable about most areas of photography, but seem to have a major chip on your shoulder, a total blindness as it were, when it comes to the benefits of optical image stabilization.
Image stabilization is one of the most-recent advancements in lens design. It is a tool that has many good uses, and yet, you continually, and repeatedly act as if image stabilization technology has absolutely zero benefits and zero worthwhile uses.
I just cannot understand why you are so utterly blinded to the simple science that underlies image stabilization. Why do you persist in repeatedly dispensing flat-out ignorant and bad advice, over and over and over again, for years on end? I simply cannot understand this Luddite tendency in your thinking.
