Is FX sensor size really neccesary?
Of course the larger sensor size usually means more megapixels and slightly larger photo-sites and thus better low light, but not by much on the newest generation of dslrs.
watcha think? I have a friend content with m4/3
Definitely agree its the photographer that makes the difference.
Excerpt from "Mastering Digital SLR Photography" by David Busch
"Dynamic Range and Sensitivity
One way to do this is to give the photosites a larger surface area, which increases the volume of the bucket and allows collecting more photons. In fact, the jumbo photosites in larger dSLR sensors (so-called full-frame models) allow greater sensitivity (higher ISO settings), reduced noise, and an expanded dynamic range. In the past few years, a metric called pixel density has provided an easy way to compare the size/density of pixels in cameras, even those with different absolute resolutions. For example, two cameras from one vendor share the same 12 megapixel resolution. One has the typical APS-C sensor size (more on that later) measuring about 24mm × 16mm, and with 3.3 megapixels packed into each square centimeter of sensor area.
The other camera is a full-frame model with a 24 × 36mm sensor, and with more room in its larger sensor to fit in 12 megapixels worth of photosites, it has a pixel density of only 1.4 megapixels per square centimeter. Clearly, the camera with the larger sensor has larger pixels that are more sensitive to light, and which can provide better image quality, particularly at higher ISO settings.
Pixel density allows you to compare non-similar sensor sizes and resolutions, too. The same vendor offers a 24 megapixel camera with a 24 × 36mm sensor. It must squeeze 2.8 megapixels into each square centimeter. So, as you might guess, this camera’s pixels are smaller than those of its 12 megapixel stablemate (and therefore not as sensitive to light). Its resolution is higher, but high ISO performance is not as good. Indeed, the 24 megapixel camera’s 2.8 MP/cm2 pixel density and light-gathering power is more similar to that of the 12 megapixel APS-C model with 3.3 MP/cm2 pixel density."
Also I've been fudging around with the d600, and can appreciate the differences. But the differences arnt large enough for me to spend the extra money, I'd rather spend money on glass
I am curious whey video cameras have never moved past s35. Probably for the same reason they are stuck with 24 fps while the gaming world can experience 120 fps and love it.
