I'm planning on purchasing a Canon 1100D with an image stabilized lens.

However, I've found two offers with different lenses. Can you explain to me the difference?

  1. Canon EOS 1100D + EF-S 18-55 IS II
  2. Canon EOS 1100D + EF-S 18-55 DC III

A similar offer on amazon.de suggests that offer 1 has an image stabilizer, but I don't know about offer 2.

Canon's overview for lenses with EF-S mounts does not use the descripton DC. The reason for why several third-party resellers use this description remains unclear to me

This list on Wikipedia suggests that the DC version of the lense is the basically the same, but without image stabilization.

Description

EF-S18-55mm f/3.5-5.6 III

The Canon EF-S18-55mm f/3.5-5.6 III is a lightweight, compact standard zoom lens specifically for cameras that take EF-S lenses. Featuring a high-precision aspherical lens element, the lens compensates for chromatic aberrations that can occur while zooming to deliver high-resolution, high-contrast imaging performance. Through optimized lens positioning and coatings, the model greatly minimizes the flare and ghosting commonly associated with digital camera photography. It is a worthy successor to the EF-S18-55mm f/3.5-5.6 II and features a revamped external design.

EF-S 18-55mm f/3.5-5.6 IS II

The new Canon EF-S18-55mm f/3.5-5.6 IS II inherits the highly regarded optical design utilized in its predecessor, the EF-S18-55mm f/3.5-5.6 IS, released in September 2007. Featuring a high-precision aspherical lens element, the lens compensates for chromatic aberrations that can occur while zooming to deliver high-resolution, high-contrast imaging performance. Through optimized lens positioning and coatings, the model greatly minimizes the flare and ghosting commonly associated with digital camera photography. Furthermore, the EF-S18-55mm f/3.5-5.6 IS II includes an optimized control algorithm that has been aligned with the Image Stabilizer structure and characteristics, achieving image stabilization equivalent to approximately four shutter-speed stops.

Based on a shutter speed of "1/(focal length x 1.6)" seconds, considered the limit to prevent hand shake during hand-held photography.

With reference to This Post (at the bottom)

The new EF-S 18-55mm f/3.5-5.6 III lens. (Source: Canon.) The EF-S 18-55mm f/3.5-5.6 III is a standard zoom lens that is light and compact and will replace the standard kit lens with future EOS kits. It includes aspherical lenses and coatings plus a redesign that positions elements to minimise ghosting and flare. Consisting of 11 elements in 9 groups it has a circular aperture and optimised AF control.

Looks like a non-stabilised version

The new EF-S 18-55mm f/3.5-5.6 IS II lens. (Source: Canon.) The EF-S 18-55mm f/3.5-5.6 IS II is a second-generation standard zoom lens with built-in image stabilisation that provides a shutter speed advantage of approximately four f-stops. Light and compact, is has a similar optical design to the EF-S 18-55mm f/3.5-5.6 III and weighs only 200 grams.

You should make a choice based on sample images and functionality - look at flickr and find the specific lens group
