Using a lens designed for crop bodies on full frame, SAMPLES.

[ Edited ]

Because the question keeps coming up I've shot a set of samples using a Tamron 18-270 VC on a Canon 1Ds mark 2. I've also shot a pair of photos (they aren't great) to show that the lens mount is similar to a Canon EF mount rather than the Canon EF-S mount. I've owned the Sigma 18-200 & 18-200 OS & they also had a rear mount area similar to the EF mount & can be mounted & used on full frame but with similar results image wise. PLEASE NOTE this is just for informative purposes & I am NOT saying you can or should use lenses designed for crop bodies on a full frame body because I have only done it with the equipment mentioned here & do not have access to all the other possibilities out there. Canon brand EF-S lenses extend further into the mirror box area & ARE NOT usable of full frame bodies without potential problems, and some could be serious.

The lens mounts compared, Tamron 18-270 VC (left side) & Canon 24-105 L IS You can easily see why the lens designed for a smaller sensor can't direct light to all of the much larger sensor used in the full frame body.

Nice, hopefully it will help people understand the difference.
