First random image of my headphones at work after plugging new Canon 50mm f/1.4 lens onto the camera. Very happy that under room light setting, I am able to shoot at ISO 100, 1/90 seconds at f/1.4.
Review of the lens
After spending most of my time shooting with L lenses, the lack of color vibration is fairly prominent to me. The sharpness difference is also fairly pronounced in detail, but not that you can see it on Flickr anyhow. (most people don't view large)
Review of the headphones (while I'm at it)
This pair of cans retail for around $249. I also have a pair of K701 at home, which I plopped $449 for. The difference is noticeable but very marginal.
