WebOverall, this is an easy camera to love. It is very light, quiet, and feels like it has a shutter at least as smooth and quiet as the F100. In fact, I suspect that the N80 may have a smoother mirror and shutter mechanism than the F100, and therefore may give sharper results with long lenses on tripods.

Web17 feb. 2010 · 44 – 46 HRC. 47 – 50 HRC. Follow-up Answer: Tempering charts indicate that you will be around 46 HRC at 1175°F (625°C) and 44 HRC at 1200°F (650°C) and perhaps as low as 42 HRC at 1250°F (675°C). Your results may vary somewhat since they are chemistry dependent. You really can't achieve less than 42 HRC by tempering. WebThe chief advantage of Rockwell hardness is its ability to display hardness values directly. The result is a dimensionless number noted as HRA, HRB, HRC, etc., where the last letter is the respective Rockwell scale.
