Crop factor...
If you have a 50 mm lens, it is with a 1.6 crop factor actually an 80mm.
You have to multiply the lens "mm" number by 1.6.
Of course the 50mm is always a 50mm and does not change magically into an 85 mm lens.
Someone needs to work on his consistency.
Kenny, you are getting all worked up over nothing. For people who do not have your advanced understanding of optics, the distinctions you wish to assert as so important are meaningless and irrelevant.
The reality is that the crop factor does cause a 50mm to behave, in terms of the perceived focal length, like an 80.
Cool your jets guy, you are beginning to make yourself look like a man who forgot to take his meds.
The distinctions, while you may not grasp them, are quite significant. For instance, DoF of a 50 on an APS-C and of an 80 on FF will be different. The "crop factor" comes up altogether too often on here, and we are constantly trying yet again to see that board members get information that is helpful and, most of all, correct. It's not an easy concept to grasp, which is why there's so much misinformation about it, and why it's so important to get it right.
