>>4264143>infinite primescalling zooms "infinite primes" is retarded. a prime lens is an optical formula designed and optimized for a specific focal length. a zoom lens optimizes for a focal length and then moves elements to zoom in and out, which means you're always going to have certain focal lengths where it's sharper and less sharp. the only difference is you're doing it before taking the photo, so you get the same output resolution. but only a retard would fool himself into thinking he has "infinite primes" as a result. if this was the case, everybody should just buy a superzoom because that would get us the most versatility. the best lenses would simply be the ones with the widest focal length ranges.
look at any review of the sigma the poster I replied to mentioned. it's a solid zoom lens, but nobody's saying "wow this is as good as a prime lens at every focal length in the zoom range". don't be retarded.
