Why is my 18105mm kit lens so bad at macros? Graham Collins, South Pacific
Rod says… Graham explains: “In my film days I used extension rings to get a magnified image. My digital images are sharp with a prime lens. So what’s the problem with my kit lens?” Well, probably nothing, except that modern zooms are more complex than traditional primes. By using it with extension rings you’re forcing it to focus much closer than its optimum focus range.
