I believe so.
I may be missing how it actually works but 55mm on my DX kit lens is more zoomed in than the 50mm, Definitely not as people describe it "Looking like a 75mm" unless the DX 18-55mm kit lens does the same thing on a crop sensor.
Either way this lens is so much better than that noisy 18-55 zoom lens, I don't have any desire to put the stock lens on my camera again. :thumbs up
