AF Focus Test Charts

I have to say that I was never happy with my Nikkor 85mm F/1.4 AF-D lens outputs.  After using it on D800E and D3, I was sure that its AF is off – back-focusing….  So I looked for some good AF Focus Test Charts on the internet and found some.

I must say that I am rather disappointed with the results of my AF testing on all of my current Nikkor lenses.  Only one lens is spot on and the rest needs some AF Tuning on the both cameras.  For some reason, they all experiences back-focusing and none with front-focusing…

Camera Resolution Test

The new Nikon D800(E) produces 36MP shots out of the camera and I always wonder how they compare with medium format digital back(MFDB) outputs like Hasselblad H3DII-39.  In the camera world, size matters!!!  In the film world, film size matters!!!  In the digital world, the sensor size matters!!!  The question is about the 35mm format lenses.  Can they produce 36MP cable images?  I am not going to even try to answer this question.  Here are some of the charts that I use to compare/discover the resolution of the lenses and camera sensors.

Hasselblad H-series Battery Recalibration/Reset

 

The process to re-calibrate the full battery gauge:

1) Charge the battery for 8 hrs in the charger.

2) With NO battery, lens or viewfinder installed on the camera, press the orange on/off button for a few seconds to make sure the camera is fully discharged.

3) Press the flash and menu buttons at the same time on the camera grip, and hold them as you install the freshly charged battery.

You should then here a rapid series of beeps(three short beeps within a second or so on H3DII/H4D) indicating the PMU on the battery has been reset. If not, repeat steps 2 and 3.

With the battery installed, press the button just above the on/off button and hold it to see the battery status. It should read 100%

MacPorts – MustHave

Web Site: http://www.macports.org

OS X is an UNIX OS.  The Aqua GUI is nice an all but in order to get the full potential of OS X, you should know how to work with the Terminal(xterm) and scripts.  Other free *NIXes have developed a nice package system and it is MacPorts that does package managements on OS X.

Requirement:
You need Apple Xcode Development Tools.  Get it from AppStore(Link):
AppleStore-Xcode

It is free!!!  After it is installed, you need to accept Xcode EULA by either running xcode or entering the following command in the Terminal:

% xcodebuild -license

Go to Applications then double click on the Xcode so it gets installed on the system.

Xcode-Welcome

Now the Command Line Tools needs to be installed.  Go to Xcode->Preferences->Downloads:

Xcode-Pref-Downloads

Click on the “Install” button next the the Command Line Tools.

 

Now, MacPorts can be installed via .pkg/.dmg and the links are:
Mountain Lion: https://distfiles.macports.org/MacPorts/MacPorts-2.1.2-10.8-MountainLion.pkg
Lion: https://distfiles.macports.org/MacPorts/MacPorts-2.1.2-10.7-Lion.pkg
Snow Leopard: https://distfiles.macports.org/MacPorts/MacPorts-2.1.2-10.6-SnowLeopard.pkg
Leopard: https://distfiles.macports.org/MacPorts/MacPorts-2.1.2-10.5-Leopard.dmg

After downloading the .pkg/.dmg, simply double-click on it to get it installed.

Self update: in a Terminal type the following:

% sudo port -v selfupdate
