Jennyhappy2: 1" compact pocket camera F1.4 for $699.

End of story.

@Richard Butler. You are right except 2 things:

1. Exposure time will be aporox. 2 times different for F 1.7 and 1.4 (which can be crucial in many cases)

2. Area size and distance to light compensate each other only in theory. In real life we have sensor own resistance, own noise, min detectable light threshold, etc. So, the closer to light - the better.

@Richard Butler, "this means they'll have access to essentially the same amount of total light if shot at their respective aperture values and the same shutter speed" - this is irrelevant. What is relevant that this same amout if light hits different areas causing different light intensity and, hence, different electric responce in pixels. Which is exactly reflected in their dirrerent effective apertures - 1.7 and 1.4.

In fact, nothing prevents to make aps-c or even full frame lens as small as we want - provided we can build strongly non homogeneous optical medium. Or, even the same but with dynamic optical properties. Some day... I'm sure. :)

Peiasdf: I said this before and I'll say it again. I want a RX100 merged with an iPhone5. Why put a 21x zoom on a "compact" camera "phone" is beyond me.

Just because it's the only good this one can say about this p.o.s. - big zoom number. And because super zoom is the easiest to make for tiny sensors.

What is missing here is downscaling comparison when downscaled images are the same size. I.e. comparison of downsizing engines.

TS and FT? Are these guys crazy? Do they think TS sounds offensive outside of North America? Or they think FT sounds offensive inside?

And please don't tell me this is because of different video specs. To change language is more difficult but cameras support several dozen of languages now. Changing video specs should be just one simple menu item. Or I missed something?

ybai011: ISO is embedded in the JPEG file. ISO 6400 for this one.

Where in EXIF did you find number 6400?

EXIF says "ISO - ISO 1". How smart, Nikon! :))

On article Nikon 1 System First Impressions (248 comments in total)

As I see it aims for the market of enthusiast compact cameras which currently have 10-12MP 1/1.7 sensor. Nikon 1 should deliver better IQ. But:

1. Due to much slower lens, for low light conditions it has to use higher ISO by 2 stops, e.g. 3200 against 800 for Panasonic Lumix LX5 or Canon S95/S100. Is its pixel size 4 times bigger? No. Hence, IQ will be worse despite bigger sensor.

2. Including lens, it's 2 times bigger and heavier.

3. Including lens, it's 2 times more expansive.

In total: my big doubts.

In reply to:

amscmu: power zoom and power focus are crap esp power focus.

They cannot match with the precision from mechanical focus.

powerzoom is another story, if you don't mind with precision, PZ is ok. However, PF is unacceptable.

Long ago when I first bought my first AF SLR, the minolta 3xi was on my top list. however, when I tried power focus. I just put it down. Unacceptable.

However, if you mean to use AF all the time, i think this lens is great (for its size).

Just to rephrase a bit...

...Digital cameras are crap, especially digital cameras with not full frame sensor. They cannot match the image quality of film cameras. Long ago (in 1999) I bought my first 1.5M pixel digital camera. However, when I tried to shoot I just put it down. Unacceptable.

Well, photos at ISO 3200 look exactly like TL500 photos at 800 (blotchy), and worse than similar from DSLRs. Samsung has to improve their noise reduction software, that's for sure.

astigmate: I still wonder why do people buy such cameras... iso 100 look like cr@p, like all other compact theses days. Go get an entry level DSLR or mirrorless 4/3 / aps-c

For me it's not the price, it's weight and size which is the main factor.

Realll: Come on...It sounds like FZ35 upgraded with 1080p and creative options! No RAW? Big deal... I own FZ35 and never shoot RAWs. Why do post process if the JPEGs are good? :)

The water is good, I'm fine! - kept telling itself chicken when it was put in boiling water for broth. ;)
