Allan Bell Posted July 20, 2014 Share Posted July 20, 2014 Just looking at Fuji X mount for this post but there are others. Why oh why do manufacturers still designate the focal length of lenses as if they were being produced for a FF (35mm) sensor camera when in fact they are made for use on crop sensor models and will probably never be used with an FF model. (Not unless there is an adaptor and the tog wishes to obtain a certain effect.) It would be so much simpler when looking at which lens to use with a crop frame sensor body if it was marked with the crop frame focal length without having to carry out complicated maths to find the true focal length for a lens which is actually made for that camera. Just in case I am not making myself clear. Fuji XF 18 - 55mm lens (as marked) is actually 27 - 84mm (according to Fuji) on the X-T1, X-E2 etc. Would it not have been simpler to have marked it with 27-84? Or are we all now brainwashed into the "standard" designation and it would be foolish to change at this late stage? Allan Link to comment Share on other sites More sharing options...
