Is this a problem? Tamron 70-200mm 2.8

I just received my copy of the Tamron 70-200 f2.8 from B&H and have been doing some test shots around the house. Optically it is fantastic. It is sharp at all focal length from wide open on and it doesn’t appear to exhibit any front or back focus issues. However, I noticed as I was removing it this evening that the aperture lever is at an angle. As far as I know normally the aperture lever is perfectly vertical and moves horizontally. The one on the 70-200 is at an angel and moves in kind of an arc. (See photo below) I did a side by side exposure comparison with my Tammy 28-75 from 2.8 all the way down to f32 and the exposure looks right on. Should I be worried about this?




Thanks,
Mark

I just checked my 70-200, the lever on mine is at an angle as well. The previous user had no problems with the lens so I guess it's just the design

Whew, that takes a load off. Thanks! I was worried I might have a problem and have to play sample roulette.
