Is actually large enough to cover a full 35mm frame (though obviously not at high quality With a regular EF lens, and the image circle (or at least the illumination circle) From 22mm up, the back focus distance of the lens isn't any shorter than can be used Was that the reduced back focus distance is only present between about 18mm andĢ2mm.
Well, maybe, but what they failed to realize They reasoned that since it didn't have to cover the full 35mm frame and since itĬould be made to operate closer to the film than a standard lens, it's performance wouldīe much better than expected for a $100 lens. The EF-S lens was greeted with what perhaps amounted to over expectations by some Specificationsġ1 elements in 9 groups (1 aspheric element)Ģ.7" x 2.6", 6.7oz. Only needs to be large enough to cover the area of the sensor. Smaller than that of full frame 35mm cameras because the sensor is smaller and the mirror The mirror on the Digital Rebel (and EOS 20D) is SLR mirror must not hit the lens when it flips up. Wide-angle lenses, but the limit in SLR cameras is determined by the requirement that the There are certain advantages in lens design in having this distance small for Back focus is theĭistance from the rearmost point of the last optical surface of the lens to the film or The "S" in EF-S stands for "Short back focus".

There'sĪ article right here on this website about how to make the modifications - Modifying and EF-S 18-55/3.5-5.6 for use on an EOS 10D If you're prepared to do some surgery on this lens, you can modify it to work with an EOS 10D. Which is currently the only other Canon EOS body designed to accept EF-S mount lenses.

Into the camera body than a normal EF series lens.It is also fully compatible with the new Canon EOS 20D, Mountable on the Digital Rebel (EOS 300D) body since it has a reduced image circle (enoughįor the Digital Rebel "APS-C" sized sensor, but not enough for full frame 35mm) and it sticks further The EF-S 18-55/3.5-5.6 is an unusual Canon EOS lens. The optics of the USM version are identical to the non-USM version, so the results and conclusions reached in these tests are applicable to both the USM and non-USM lenses In Japan this same lens was available with a USM motor, and now the USM version is available in the US and is being sold with the new Canon EOS 20D.
Note: This review was written after testing the original EF-S 18-55 lens which was supplied in the US with the Canon EOS Digital Rebel (EOS 300D).
