sensor size
Sep 29, 2013 10:16:00 #
I want a digital successor to my Roliflex, but can't see where sensor sizes are given. "Full frame" is obviously greater then "point & shoot", but where could I determine the real value in the combination of megapixels and sensor size. I have had a Canon A630 for years now, and it is a terrific little p & s.

That is a very informative chart. Should I assume that the, ah, densities are equal?
It merely shows the size relationships of different formats.
Density (I assume you mean number of pixels) would be specific to each manufacturers' sensor.

The problem of course, is that while I assume that pixels are the equivalent of grain in film, I don't have a concept of how different sensors compare.

You can get full frame sensors in 12, 16, 21,22,24,38 megapixels as far as I know.
And APSC in 6,10,12,16,18,21,24 megapixels.
Some of these numbers are 6 year old cameras and there might be a couple of mistakes in there, but you get the idea.

Spend some time with Google. :) It is your friend. When you have explored the basics, you may be able to pose a question that has a definitive answer.

Thanks. My Google searching needs to be narrowed...
You are correct. Photography has a never-ending learning curve. If anyone ever thinks they know it all, they're misinformed. :)

I don't understand how 16MP doesn't equal 16MP and equal 16MP. Aren't they all 16,000,000 pixels? Does sensor size really matter? If anything is different from camera to camera, it is the shooting program that drives the image capture... the "goodies", many of which are just marketing tools.
The most overriding factor in photography, I believe, is the photographer... the vision... the skill level.
That's not what the camera companies want you to believe... they are in the business of selling cameras and sensor size is a convenient buzz generator.

Read the article referenced just above your post. It does a nice job explaining the relationship of sensor size and pixel density. In general,the sensor size does matter. How much it matters depends on the kind of photos you take and how you plan to use them.

The sensor information was an interesting read. Information exchanges like that are why we read things like UHH. thanks for posting it Bill, it is appreciated.

You are comparing pixels, rather than images. The article explains it all. :)
All things being equal (pixel-wise), the larger (physically) the sensor is; the better the image.

Clif, you're most welcome.
I just joined a few days ago and find that some of the questions posted on UHH are really thought-provoking.
Since Google is my Friend, I have been learning as I go. :)
