comment If landscape photography is my focus, does it make sense to use Nikon over Canon?
You might find that investing in some ND and gradient ND filters can help solve a lot of the dynamic range problems that landscapes pose.

comment Why are high-end compacts still shipping without GPS?
@jrista: The expense isn't just in the cost of the GPS hardware, it's in the non-recurring engineering it takes to add it to the camera. The hardware in any camera you're going to want to carry is so tightly integrated that plopping an additional component into the design is a major effort. GPS is happening on some new cameras because it's become available pre-integrated on new versions of the processor being used by the manufacturer.

comment What is the proper composition when shooting two persons standing by each another?
Now that I think about it, if my goal were to get only the couple, I'd compose it vertically. Then you can follow the rule of thirds all you like. Losing the fence and the barn would really rob the image of a lot of context.

comment Can Nikon FX (full-frame) users use DX (APS-C) lenses?
...and sometimes the crop out of the center is more than enough to provide a usable image.

+1 for rules being meant to be broken.

comment What is the proper composition when shooting two persons standing by each another?
Your sketches are missing a critical background element: the fence. The fence draws your eye into the right two thirds of the picture, which is essentially square.

comment Which impacts the speed of focusing more, the lens or the camera body?
@jrista: The question the OP asked was which part contributes more to focusing speed. The biggest consumer of time in AF is moving the optics, which has been the case since since the first time I laid hands on an AF body (Minolta Maxxum, mid 1980s) and still is. Micro adjustment is entirely irrelevant; it's there so the end user can force the firmware to apply an offset to correct for a consistently-wrong solution. That's a manual adjustment in my book and doesn't change the system's speed or accuracy.

comment Which is the first camera that introduced dial method to set values?
Do you mean electronic controls or mechanical? Some of the folding Kodak Brownie models from around 1905 had a dial that set the shutter behavior, and I'm sure there must have been others that came earlier.

comment Why does my DSLR's viewfinder ignore the aperture ring on a legacy lens?
It would be helpful to know exactly which lens you're using, as it will have a bearing on the answer.

comment Can the camera select wrong exposure just because of color?
@enthusiast: The histogram is just a plot of levels of brightness on the X axis and how many pixels are at that level on the Y axis. Usually this is done for the color channels plus one of the overall level. What I looked at was multiple histograms for small crops within the petal areas of each flower. The red picture's crops showed pretty consistent amounts of light all the way around where the white's showed less light on its right side than on the left. I did that as a way to quantitatively determine if one side was brighter than the other in case my eyeballs were off.

comment Can the camera select wrong exposure just because of color?
@enthusiast: I just took a look at the histograms for several square areas that consisted of just the flower petals. The red one is pretty evenly exposed all the way around, but there's a definite shift in brightness between the left and right sides of the white one. That difference will have an effect on what the metering system sees.
