This series takes a different angle on the same subject, this time at 50mm. Focal point is the 3 bands cut into the upper part of the pen. The dark shadow in the upper right may be the desk lamp's shade, but it could be vignetting from the UV filter I normally have mounted.
At f4, only a very small point on the subject is in focus, but the subject is fairly recognizable.
For some subjects, this effect could be desirable, but I think it'd be the exception.
