Re: ISO?
In reply to Tommy tek, Jan 30, 2011

ISO, aperture, shutter speed and lens characteristics all contribute to the quality of the photo. It seems it is always a trade-off. The shot was taken at 135mm (202mm for 35mm equivalent). Assuming that one should generally be able to hand hold a shot at a shutter speed of 1/focal length (the general rule of thumb for 35mm film) for a stationary subject, 1/67th for shutter speed should be OK when using SSS (providing about a three stop advantage). So, ISO-100 might be reasonable for slightly better IQ. But, given it's the Beercan, I would stick with ISO-200 and go to f5.6 where my Beercans are far sharper than at f4.

Looks like a nice copy of the Beercan. That shot is pretty sharp for f4.
