Not really, if you limit yourself to continuous light. But if you work with a modern flash which a zoom function, then it is convenient as it removes one source of error, a too narrow cone of light for the lens used.

In practical terms, EXIF data ... but that's about it really.

 

There is some cyan drift and vignette correction if you code the lens but it's pretty minor and won't be noticeable unless you're shooting images with critical colour requirements into the corners of the shot (snow drifts, foggy days, white billboards etc). It does make a difference but if you're not sure you may be best to get a UV/IR and try it uncoded to see if you notice it.

 

Sean Reid has a comprehensive review of 50's and coding/filter use on his site. You can read all about the coding and cyan drift corrections there in detail. He has his own opinion about coding there.
