[QUOTE="BackdoorArts, post: 214023, member: 9240"] Noooooooooo!!!! (here we go...) If the 105mm is considered proper perspective on full frame and film it's because of how it renders the image and not how far you need to stand from your subject. A 70mm lens on a DX camera will allow you to stand in the same place, but it will [B][I]look different[/I][/B] than the 105mm on the FX. "Proper perspective" has to do with the relative position of facial components to each other and now how large the head is in the frame, and the 70mm lens on a DX will show a slightly different orientation of those components (eyes, nose, mouth, ears) than the 105mm on the FX. [B]Period. [/B]There is no way, short of post-processing lens correction trickery, that will allow a DX and an FX camera to take the same photo from the same spot and look [I][B]exactly[/B][/I] the same. Not that there's anything wrong with that!! The only reason I rant about this here is that the point of the original video is one of facial feature orientation, distortion and perspective, and that has everything to do with the focal length of the lens and not with how close you are to the person. If a 105mm is considered proper perspective on an FX then put it on a DX and stand back farther - though doing that will also change the relative perspective of the facial features. If 105mm is perfect on FX then I'm going out on a limb and saying an 85mm will likely get you there on a DX. You'll be a little further away to get the same head shot perspective, and that added distance will compensate for [I]some[/I] of the perspective difference created by the lens. In both cases at least you're dealing with a lens that does not "stretch" the facial features. [/QUOTE]
