Thanks for explaining the pictures. The last one looks great! I'm still trying to decide which of the "bakers" I am. I think I may try & read a book or two before I make a decision.
You know, it's funny. There aren't too many people who have the latest and greatest of cameras every year. They often buy a system and stick with it for a good, long time. Sure, they upgrade from time to time. But when they do, they sell their "old" cameras to someone else (who presumably uses them), or, like myself, they keep the old one and use it as a backup, such as at times when switching lenses would be inconvenient. We also from time to time have people come on here who are buying older used cameras cause that's all they can afford. It is often a recommendation made to people who want a nice camera but are just starting out.
So what happens when all these people are walking around shooting with older cameras?

Are they getting terrible, inferior pictures? No, they're not - well, unless they're terrible photographers, lol. No, but seriously, they're probably going to work hard at learning and improving their skills as they go along, which will happen naturally as they see what works and what doesn't. This is pretty much how it is with most people wanting to learn. The process can be intimidating at times, and frustrating, but it's also fun, and the rewards are worth it when you begin getting pictures that people ooh and aah over. It's like riding a bicycle, too - once you learn how, you don't forget, and you can also transfer your skills to any bicycle.
But here's the real point I'm trying to make. Getting good pictures is really something you have to work at, at least a bit. Otherwise, and at the risk of getting flamed,

you are a "lazy" - and probably unrealistic - photographer. What do I mean by that??

Well, I mean that you (global you) think you'll pick up a camera and get fantastic pictures without putting any effort in at all. And I'll offer that what you'll likely get in that instance is snapshots, not really "works of art". (And granted, that may be all you want, and if that's the case, then more power to you!) But it doesn't have to be that way. With just a little bit of effort, you can get pictures that people ooh and aah over. (And the only person you may care about oohing and aahing is yourself, and that's ok, too! Although as photographers, we tend to be pretty critical of ourselves, and may always strive to do better regardless.)
As mentioned upthread, I've always used a camera system that has had a weak point (and they all have them) of greater noise at higher ISO. The way I worked around it, because I really loved the system, was to learn to shoot using lower ISOs and other principles of exposure and tools of the trade that were available to me (for instance, a tripod, noise reduction software, etc). If my pictures tend to be a little noisy, I'm ok with that - as long as they're otherwise really good (to me - pictures that *I* am happy with has always been my own personal goal). I am intrigued with the newest camera from my manufacturer that offers the latest and greatest sensor that is much better with noise at higher ISO. Does that mean I'm going to run out and buy it? Heck no! I don't HAVE to. If I want to, I can, and surely it might make my life easier and more exciting. But having learned to get the types of pictures I want already, the camera I use doesn't matter too much other than it has to be one I
enjoy using, and those are my own. Noise is one factor that may be undesirable in photos, but there is so much more! As I said before - boring subject matter or no subject at all, poor lighting, crooked landscapes, poor focus, blur, etc., may all be more objectionable to the viewer.
To further illustrate my point above, I'm going to again refer to an article I posted a couple of days ago. It's a good article, demonstrating the use of prime lens vs a zoom lens. (That I posted for the OP to demonstrate the use of various lenses on the NEX vs a zoom lens on a pns.) I'm going to ask you to re-read it, but this time, substitute the concept of "zooming" with "high ISO".

Done? What's my point? Sure, you can flip a switch, or use Intelligent Auto or whatever it's called, to brighten pictures. But is that really the best way? Or is it the "lazy" way? What about
finding great light (with light being one of the most important aspects of a photo)?
Finding great color, texture, visual interest?
Striving for better composition, etc. Pointing and shooting will always be just that.
Since there are people here who are new to this and also want to learn some basics, I'm going to add this book to the link I posted earlier (reposted here as the second link). Don't laugh or discount Kodak cause they've been helping generations of people take better photos! These are really simple to read and will help you on the road to getting better pictures without being overwhelming. It's a good start. Take a look though some of the pages of the first book, it will echo a lot of what's being said here. Something to think about.
