I guess not. In fact, if it says: "equivalent to 24mm of the 24x36mm", then I will have an idea what I will be seeing, what field of view I will be seeing through my crop factor DSLR viewfinder because I am used to the 28 of my film day. So by saying "equivalent to 28mm", it is telling me that although the focal length of the lens that I am using is a 17mm - which will never change, my photograph will looks like one that I will get if I am using a film camera with a 24mm lens on it like I did in the film days.

Now, for those who grew up with crop-factor digital camera, or old enough but have never shot 135 film cameras, then it may be confusing. I don't know
