Shutter Speed: 1/10
Focal Length: 50 mm
Well, he was right. Though I'm very happy with my kit 18-55, and I think it gets really good results, the 50mm is sharper. Noticeably so.
After lots of experimentation with different apertures and compositions, I decided I like this one best. The DoF isn't paper thin, but the entire lock is not in focus. Also, the centered composition made this photo a good candidate for my Motionless series, and after applying the effect in Photoshop, I liked how it fit. The only thing was that since I had white background, I had to dial down the vignette opacity quite a bit to avoid it looking too harsh.
