Let's assume that both sensors have the same pixel count and that the crop factor equals the teleconverter magnification. Then in theory, the answer seems simple. Both do the exact same thing: simply use the centre portion of the image. The smaller sensor does it by placing the same number of pixels in the central image area. The teleconverter does it ...

It depends entirely upon the teleconverter in question, the lens in question, and the full frame and APS-C cameras in question. The same is true when comparing a full frame camera + 1.4x to an APS-C camera when both use the same lens. Optical quality is never better than the weakest link in the equation. Adding a low grade TC to a high grade lens and camera ...

It's difficult to be sure. The lens-camera system is a complex one. Making any changes to it can have unexpected consequences. Using a APS-C camera on a FF lens does throw away some of the useful light gathered. But interposing an alien lens cluster in the form of a focal reducer or teleconverter may or may not do more damage to the overall image quality. ...

By the way, while the Michael's answer is absolutely correct and practical (you need a new lens!) it might be interesting to learn that you actually CAN achieve the same FF look without changing lens under some circumstances (other than stated in the question - it will not work with 600D and with street photography). And yes, technically this is a comment, ...

You can't. What we refer to as equivalence is only an approximation. You can't put a different lens on a crop sensor camera and get the same shot with the same field of view from the same shooting position with the same depth of field using the same ISO and the same shutter time as you can get with a full frame camera. The converse is also just as true. You ...

How much do i have to step back in order to compose my picture? That depends on how close you were to the subject in the first place. Which lens is better and why? It's really not a matter of what's better. It's just what you want. So, yes, a 35mm lens on a camera with a 1.6x crop factor behaves about like a 50mm on a full frame camera, and 50mm ...

You said you own an 18-55mm zoom lens. You can just set that one to 35mm and 50mm (there is a scale on the barrel that tells you what focal length your current zoom position corresponds to). That way, you can see the field of view each focal length gives you for yourself. Even though the same focal length will give you a different field of view on ...

The result of using the lens on a crop body is the same as that of using it on a full-frame body and then cropping. To possibly clarify: A picture taken with 1/100s at 50mm/2.8 and ISO 100 on a crop body with have the field of view of a 75mm lens on an FF body, the exposure of an image taken at f/2.8 and ISO 100 on an FF body, the depth of field of an ...

Getting the exposure spot-on is the key to the kingdom in photography. To accomplish this we regulate the amount of light energy projected by the lens and adjust the length of time this projected image is allowed to play on the surface of the digital sensor or film. Too much and the image will be washed out, too little and the image will be gloomy. Now ...

The same light will pass through the lens regardless of the type of camera to which it is attached. Less of that total amount of light will land on the smaller sensor. But exposure, when discussed in terms of varying sensor/film sizes, is not about the total amount of light falling on the sensor. It is about field density, or the amount of light falling on ...

The amount of light passed through the lens stays the same, the lens will still be a F/2.8 lens. Since the smaller sensor only crops out a different area from the illuminated circle, the exposure related properties of the image taking process will stay the same, regardless of the crop-factor.
