Just wondering if someone could clear it up for me.

Kit lens at widest is 18mm and f3.5, not too far from 14mm and f2.8, plus has autofocus and can accept filters.

Field of view at the wide end is more dramatic than at the long end. The difference in the diagonal FOV of the 14mm to the 18mm is a little more than 14°, 77.4° vs 91.7°. For example if you have a subject distance of 10 feet, you will get 17 feet, 1.7 inches of horizontal scene with the 14mm. At 18mm you would only have 13 feet, 4 inches of the horizontal scene. Real world example; the average car is 16 feet, 4 inches, so at ten feet you would be able to get the whole car into the shot, and then some, with the 14mm, whereas with the 18mm, you probably would only be getting the car from the doors to the trunk in the shot.

Thank you
