If you've been with GX GARENERINGS for some time, you've learned a number of Cantonese expressions. While Mandarin or Putonghua is called the national language, Cantonese has a stronger links to the old Chinese culture as it retains a close tie with the ancient Chinese language. We can talk more about this topic in some other posts.
A large part of the Chinese words is homophonic. While "yuo" means "again" when pronounced in the sixth tone, it also means "travel" in the forth tone. "Gai", as you've learnt, refers to "a street".
So, the post topic says, "travel (on the) street with GXR S10".
Like the GX200, the 1/1.7" small sense makes the S10 better suit to street photography. The improved high ISO performance allows the photographer to use as high as ISO 800 for images with reasonable IQ.
The Chinese New Year is coming. So the kiosks are covered in red because this is the auspicious colour for Chinese. Tuning the White Balance Correction can either water down or boost the reddish tone. This is really a great function to be included in a camera, especially when the user interface is so friendly.
Having used the GX200 for over a year, honestly, I am more used to the shallow DOF than the "regular" DOF given by like the APS-C sensor of the A12. So I have found the S10 more familiar. The GXR body does give the S10 an edge over the GX200 in ergonomics, not least because of the new VF-2 of a higher resolution mounted on the GXR I am using.
Another reason why the S10 is a better choice for street photography is that it has vibration correction while the A12 has none. I think for the new generation of photographers, a lens without shake correction capability is something they cannot forgive.
Using the GXR S10 for street photography is fun but as a GX200 owner, the amazement does not come as great as using the A12. For one thing, the A12 has ,unlike the GX200 or S10, a prime lens and requires the photographer to move to the right location rather than zooming the lens to an ideal focal length for the desirable angle.
