In reply to:

Carl: The Sony 12-24/4 is produced in China, while the equivalent Sigma is produced in Japan. Doesn't this mean lower production costs for Sony? Why does this not reflect in a lower customer price?

Or, by the way, reply!

I had one. It fell down in a stream and survived intact. I keep it unused for almost 2 years in the drawing and when I turned it on it was perfect. A breakthrough in the CMOS sensor.

The question is: why Canon could not do the same?

These seem to be made of anodized aluminum alloy. The same color as some cheap Chinese lantern.

But is it about subject tracking or about Nikon subject tracking?

Sony made the "simply" complex without outstand optical gain.

That was a good manner to not explain clearly what ISO means. Better, and simply, would be to say that ISO is the boost the software gives on the sensor to fit adequately aperture and shutter speed chosen in such a way as to result in an usable shot.

Ruy Penalva: Sony deceives its consumers with the launch of new upgrades on their cameras doing the old versions mere garbage. Wait a new version in the upcoming year.

So, await until the next year and: CRY!
