lately noticed many  people    including such information in their description field like what brand &model camera  and lenses used for their photograph.
I understand the reason behind it but what do you think would it help to enhance your sales and to my surprise how IS allows such copyrighted brand names in description fields while they are so strict with keywords.

I'd just like to hear your thoughts on that I am not against it but I am not for it either so your view will help me to make up my mind
thank you for your input in advance
