Canon L Lens producing higher noise/grain? (24-70mm f2.8 II)

Hi all, I just purchased a brand new 24-70mm f2.8 II for my upcoming trip. I've been testing out this lens for the past few days, and have noticed something that I'm a bit confused by.

It seems by my tests, the L lens produces more noise than my Canon 50mm f1.4 at the same ISO. Here are two awkward shots of the same subject in similar environments (100% zoom). I've highlighted the increase in noise levels.

Additionally...you can see that even at a low ISO 250, noise is very apparent...even in bright environments (100% zoom).

The ultimate question is...is this expected, or should L lens not exhibit an increase in noise level. I'm currently using the 6D, which I always thought dealt with additional noise well.

Thanks very much!

Canon EF 24-70mm F2.8L II USM Canon EOS 6D
