K20d jpeg file size

how come the Jpeg File Size of the K20d is so huge compare to k200d. K20d has about 11mb while K20d is just about 4mb. i know it has a 4.6MP difference but how can you explain the 7mb difference in file size? 1 jpeg file of k20d is about 3 jpeg files of k200d.
sony a350 14MP jpeg file size is about 5.5mb compare to k20d's 11mb. whats the advantages of the bigger file size

Better quality, in short. Few years ago I made hack for 2Mb camera that allowed to make almost loseless JPEG with about 4-4.5Mb size :-). How is this?
Choose lower compression level if you want.
You can also shot in lower quality + RAW. So, in case of emergency RAW allows to make perfect large prints or crops.

Yep, just as tr13 says, the bigger file has less compression in it. RAW is lossless - and thus is even bigger. You're probably shooting 4 star jpeg quality? Someone brought it up on the forum before - and I think he said there's not much of a difference between 4 stars and three stars.

Because the differences would only become apparent if you printed at, say, 16x20" and then looked very closely at the results. K200D and K2000 would be identical, both being 10MP cameras; the K20D would show slightly more detail, being a 14MP camera. The fact that you apparently have the K20D set to use less compression than the K200D in saving the JPEG might also play a role, but again, you'd need to be printing pretty large and looking pretty closely to see the difference.

so if you're not really printing the pics the quality is just the same when you are just using your pc for viewing.. thanks for the help.

Well if you zoom way in and crop out a small section of the picture, that works out about the same. But sure, in general, more pixels doens't really mean better image quality. The difference between the models in question is more about features, not so much about image quality.

While I've been shooting mostly in JPG, full quality, I was fiddling around and noticed that, depending on the complexity of the picture, a RAW file can be nearly the same size and a RAW+ is double the size (due to the extra JPG file).

It got me wondering but are the JPG and the RAW+ version JPG the same quality (ie. the JPG quality settings (1-4 stars, AWB settings, contrast, sharpening, etc.)?

Cheers.
