taking large quality images in crop body??

[rickp1]

I've come across some reference to a crop sensor creating a bit more noise in the image than full body sensors. I also came across some reference to taking images in Medium quality size on a crop body relieves the camera of cramming so much information and thus improving quality a bit.

Is this accurate or am I getting information from different ends of the stick.

Thanks

What do you mean by "creating a bit more image" -- more pixels? There are crop sensors with more megapixels than full-frame sensors, but there are plenty which are the other way around too.

It is true that larger sensors don't need to "cram" as many photoreceptors into such a small area, which can help with high-ISO situations. I personally don't have experience here.

Question: what are you looking for? Do you want as many pixels as possible? High ISO performance? Detail / sharpness? Those sorts of answers will help more than just "full frame is better than crop" or so forth.

At base ISO, with the same or similar lenses, you'll be hard-pressed to see a difference between most crop and full frame sensors.

The 7D starts to get a little noisy between 400 and 800 ISO, but you'd be hard pressed to see a difference in quality between that and a 1D MkIV at ISO100 or 200.

Sorry, creating more noise in the image. I'll edit.

The reason I ask is I keep hearing a lot of people talk about the 5D and 1D cameras and that they are full bodies. Also that cramming so many megapixels in a crop body affects IQ.

They're mostly talking about noise, but smaller photosites also introduce diffraction sooner compared to larger ones.

Meaning that crop sensors introduce diffraction sooner?

Thanks Richard,

This is an amazing website. How good is this bloke?

From his gallery & bio, I would say very good.
