Compared to what? If you want the perspective that the teleconverter gives you you have, as I see it, 3 options: 1. use a lens of the same focal length that the TC gives you. But do you have such a lens, and is its quality comparable with your TCed lens? 2. Take a photo without the TC and crop it to give you the perspective you want. This is likely to be lower quality than using the TC 3. Use a smaller negative/sensor with a lens that gives you the perspective and aov you want. This is much the same as cropping - does the smaller format yield better quality than the TCed lens at the print / viewing size, and do you have the appropriate equipment? If you just want to get closer and don't care too much about the perspective you also have 3 options: 1. get closer to the subject 2. bring the subject closer to you 3. a bit of both Only the second set of options is guaranteed to produce better optical quality, but as with so many things there are other tradeoffs which may mean that a TC gives you better image quality than the alternatives. "Compared to what?" is always a very interesting question to ask.
