Sensors ?

Hi all, would it be fair to say that the Vlux 20's sensor is more advanced with less limitations in camera quality file out put versus the DLUX 4's sensor? please explain why or why not

My take on this is that the quality of the New Leica VLUX 20 should equal at least and more surely surpass the DLUX4's image quality, why, because technology for these (smaller sensors ) are always improving so fast, and #2 the price point is pretty much in line with these chips(sensors) that continue to come down in price and are at least equal too there predecessors quality and more than likely much better. Thats my take on it.

No, it would not.

 

please explain why or why not

The sensor pixels were shrunk to half the size they had in the D-Lux 4.

No, it would not.

ok, that may be true, however that would not negate the fact that the technology from 2 years ago of the sensor used in the DLUX 4 may not be as advanced in the sensor used in the VLUX 20, you have to remember that sensors are like computer chips there getting smaller and faster ie; the ability to receive just as much info. And then there is the on board processor of the VLUX 20 that can out process or I would think equally process the sensors info as good or better Thats my theory:)

Unfortunately, while the sensor technology advances very quickly, the photon technology does not.

 

The sensor's main job consists of catching and tallying photons. Since the influx of photons for any given area remains constant, cutting the sensor's size in half means that it should compute the image with half the number of photons. Hence, it definitely does not receive just as much info, but only half as much.

 

You can, of course, apply the chips and the processors power to enhance the image by applying statistical methods. However, the thusly "enhanced" image is to an originally good image as the gallup poll to the actual vote.

Yep, we would need new and improved photons. Alas, even the most cutting-edge technology doesn’t provide those.

Well I guess I'll have to wait and see, because my wife's will be here tomorrow:) for her birthday, and I will do some testing too see and finalize (my) opinions as far as the quality of the final prints are, because thats all that matters, rite. And I'm sure that the processors are becoming so advanced in such a small amount of time, that these (small senors) that are used in the leica VLUX 20's will take what ever the sensor throws at and turn it into an awesome 16x20 printed photo:eek:. Theres 2 sides to the final out put, sensor size, and then the PROCESSOR SIDE, which side is really doing the work here? I think its the processor side, because you can have a great big old sensor and a lousy processor and what to you get? you end up with just an average rendered file, just my opinion thuogh. I'm no computer engineer.

Michael on the other hand does this sort of thing for a living.

 

Sometimes it's best to accept that someone else may know more about a subject than the layman.

Oh well,I'm just being optimistic here, yes I did not no that Mike was a cumpter engineer for photo sensors. I sure don't no all the detail involved in making a chips and then a processor that untangle all that info and then put it into a beautiful picture, but I'd sure like too learn, and get a better understanding about (todays technology's) and how it all comes together. If anybody has an up too date link regarding the development of the latest sensors being used for Point and shoot digi cam's please pm me with it, or post here. I'm very interested in understanding how it all comes together. Stunsworth thanks for leting me no about Mike, I feel stupid now:confused: someone please explain.

 

Best, chris m.

The simplest advice would be: if you're not prepared to believe what people tell you, you won't profit by asking.

Chris, Michael has written several articles for LFI. He is quite knowledgeable and very articulate in both German and English.

 

 

I'm sure you won't be disappointed by the V-Lux 20. It's designed to be a good snapshot camera. It is apparently comfortably pocket-sized and sports a humongous lens; and it's a lot less expensive than the D-Lux 4 to boot.

 

But all the write-ups I've seen on it stop there. No one raves about its image quality, though they all say it's fine for this class of camera.

 

Just guessing, I would imagine that it will do an adequate 16x20, but probably not as good as the D-Lux 4 at the same equivalent focal length.
