How important is lens sharpness?
Perhaps not as much as we’ve been led to believe: Lens Sharpness.
Ken Rockwell points out that in most real world scenarios, lens sharpness is just fine. Today we pixel peep to the absurd dimension, finding limitations that may not matter. And once we find the limits, there are often simple work arounds – such as stopping down the lens by a stop.
He also notes that sharpness tests are too often done by photographing a flat test chart, which bears little resemblance to our 3D world where everything is not always in perfect focus. There is a lot of interesting info in the above linked article.

Lenovo security fault called reckless
Lenovo pre-installed malware on millions of computers that broke https security for months – and then initially denied the problem. This vulnerability means systems used to log in to financial, work, online sales and other sites were compromised.
Installing Superfish is one of the most irresponsible mistakes an established tech company has ever made. Reckless, careless, and appalling don’t even come close to covering it.
via Lenovo Superfish scandal: Why it’s one of the worst consumer computing screw-ups ever.
- If you are using a Lenovo computer purchased last year, you need check for the presence of Superfish by going to this page and reading the result.
- Lenovo’s manual spyware removal instructions.
- As of this morning, Microsoft has updated Windows Defender to remove the Superfish digital certificate that causes the security failure in Lenovo computers. Update Windows Defender and scan your system.
- CHANGE YOUR PASSWORDS at secure web sites. You need to especially change your passwords at critical information web sites such as your financial accounts, health care records accounts, and online purchasing accounts as your account information had the potential of being compromised.
