Metadata lens info differences between 30D and 450D

<p>I'm a hobbyist photographer, in the process of checking out Lightroom 2.2 evaluation. I've noticed that when I filter the Library with metadata, the same EF 50mm f/1.8 lens shows up in two different categories, depending on which body it was used on. The 30D reports the lens as "EF50mm f/1.8", and the 450D reports it as "EF 50mm f/1.8 II". Thus there are two categories of pics taken with the 50mm lens. <br>

I assume this is due to the way the camera generates the metadata with each shot. Is there a way to modify the way Lightroom works so that the program would know that "EF50mm f/1.8" and "EF50mm f/1.8 II" are one and the same and display the shots together through the Library filter?<br /> <br /> Thank you for any help.</p>

<p>I do. I've found a roundabout answer to this here:</p>
