[QUOTE="TedG954, post: 155654, member: 9701"] So, according to that definition, a DX 18-55 is actually a 27-83mm. And a DX 35 is really a 52mm, a DX 50 is a 75mm, etc. I wonder why all these lens companies mis-label their products. :rolleyes: OK, so I'm a horse's ass. But if a 35 is 52.5mm, then it should be called a 52.5mm lens. As stated by jwstl, [I][COLOR=#000000]There's the belief that a [/COLOR]DX[COLOR=#000000] lens has the field of view of the focal length stated when that's not the case. The focal length is the same no matter the size of the sensor because the focal length is distance from the film/sensor and that doesn't change from [/COLOR]DX[COLOR=#000000] to [/COLOR]FX[COLOR=#000000] to film. If you want to know the field of view of your lens on [/COLOR]DX[COLOR=#000000] as it compares to film and [/COLOR]FX[COLOR=#000000] then you always have to use the conversion no matter what lens you use. [/COLOR][/I][COLOR=#000000]So, I may have purchased an 11-16mm for a D5100 believing it would be wider than my 16-35mm on my D800. That would have been a $700 mistake. I should probably give jwstl a portion of that money. Again, I'm a horse's ass and I apologize. [/COLOR]:disturbed:[COLOR=#000000] [/COLOR] [/QUOTE]
