Ok ... how much closer do you get with a 1.4x TCon? Maybe this quick pair of snaps will illustrate for y'all and help decide if you wanna invest!

The average user who needs a TC, gets it for outdoors reach. A x1.4 magnification on an object that is 10ft away from you is not the same as an object that's 200 yards away... Why isn't it the same? The same math works for both situations. Skip Douglas

The visual result and the way our brains processes zoomed on distant objects is different however. Let me see if I can dig up a good example... 5D Mark III | 135L | 24-70L | 580EXII | Flickr | Instagram

Apr 11, 2008 07:24 | #8 Here is the "best" explanation I found online at this time: Perspective The meaning of perspective is difficult to be defined precisely. Because the image of a three-dimensional scene is two-dimensional, perspective is created by the relative size of similar objects (i.e., a distant object looks smaller than a nearby similar object), converging lines, and so on. Normally, we use telephoto lenses to take images of distant subjects so that the desired portion of the scene is ``extracted'' from its surrounding environment. The distance between two objects looks shorter and hence the scene seems ``compressed'' (i.e., objects look like close to each other). We mentioned this in previous section. On the other hand, wide angle lenses are normally used to take wide area and ``exaggerate'' the nearby objects (i.e., they look like larger than their actual sizes). The rest is here (along with some visual examples): Optical Zoom 5D Mark III | 135L | 24-70L | 580EXII | Flickr | Instagram

I'd say this is a bad example because you could have just zoomed your lens from 110mm to 154mm for the same effect. The TC should really be used for extending the far range of a telephoto lens. 6D, 50D
