Originally posted by Gennatay What are the factors most consider when deciding between getting a prime lens and a zoom lens?
I tend to use zooms for general purpose and primes for a specific requirement; e.g. best bokeh, widest aperture, portability, real macro, portrait, etc. Zoom lenses are a step down in IQ, but it's sometimes hard to notice, or not that important. Mostly a zoom is about convenience. Constant lens changes can be irritating, but limiting yourself to a single focal length can be fun.
There's no need to go all prime or all zoom. They each have advantages. Something we've seen repeatedly on this forum is that the kit lens gets blamed for lack of sharpness, when the problem really is technique. Why don't you post some photos that show how the 18-55 is letting you down? There are a lot of very experienced shooters who are quite satisfied with results from the kit lens. Not that they don't have other lenses, but they still like and use the 18-55 when it's appropriate.
