I been researching cameras and am finding it difficult to get what I want without getting a heavy camera. So, I have a question after telling you what I think I understand so far.

I want high quality images, although not necessarily SLR quality since I don’t do large prints or have other needs for that. While I like the idea of changes lenses, I’m not likely to carry around all that stuff. I do want good close-ups (e.g., insects).

Occasionally, I want good telephoto/zoom capability, but not as often as good macro ability. I don’t care about capturing moving subjects (sports, kids, etc.).

So, based mostly on weight, I’ve ruled out DSLRs, most of the mirrorless SLR-like models, and the ultra-zoom compacts. Some of these fall in the “bridge” category. I still want good image stabilization and RAW capture. Plus, I like to use a viewfinder (some advanced compacts make you use the LCD screen).

I think that leaves me with the compacts with large sensors (usually 1-inch rather than the typical compact's ½ inch or less). They’re only a little bit larger overall, but not much heavier unless there’s a lot of zoom. My understanding is that high MP cameras do not have an advantage unless those pixels are spread out over a larger sensor (rather than made tiny and crammed onto a smaller sensor, which can degrade the image).

So, my questions are:

(1) am I generally correct so far? (about the features and their relationship) and

(2) when I want to zoom in to get a picture of a small object in the distance (e.g., a bird) will having more MP mean I can do my zooming and cropping on the computer and get a high quality image of a small area? I know megapixels are unrelated to zoom and do not make up for it, but I’m talking about the case of wanting only a small part of the picture and having to do more manipulation later. I understand that I might not be able to clearly see the part of the image I really want on the camera and will have to take my chances and view it on the computer later. I don’t need to print larger than 5x7 (or maybe 8x10) in those cases. If this is correct, I’m willing to forgo the higher zoom (with its extra weight) since I’d be able to get the occasional photo of a small object with a little extra effort.

I’m thinking of the new Sony Cyber-Shot RX100 II, which is similar to the existing RX100. It will have 24MP, a 1-inch sensor, 3.6X optical zoom, and weigh only 281 grams.

Thanks for reading all of this.
 
I had bought a Nikon p510 and I was very displeased with it. It had a 42x optical zoom and 16.1 megapixels. When I zoomed in on the pictures the quality was horrible, I should of waited to get a better camera. Hope that the camera you plan to use is good.

No. Zooming on the computer will ALWAYS make the image worse. You can of course crop parts until you are at a reasonable resolution, because printing 15 or 20 MP on a small print, doesn't make much of a difference (I'm only saying that since you said you don't want big prints, it will make a difference for big prints!). Way more important for a good macro is a good lens and in your camera, a chip that gives you sharp images on potentially high ISO levels. However, unless you are trying to take pics of moving animals, you can neglect that a bit for macros. If you're typically taking pic of immobile things, and even have a stand .. you might even get a tele macro lens and take decent pics! If you are doing reeeal close ups, you should get a ring flash (or try to build one on your own with optical fibers, it's not that difficult).

+ good lens
+ light intense lens

- not much optical zoom (keep your hands off the digital zoom, even if sony calls it different)
- no viewfinder
- no lens changing

How serious are you about macro shots? If that's really what you primarly want to do, you need a camera where you can get a macro lens!

Otherwise, if the price isn't the problem - get a Canon Powershot G1 X - it's only downside is that it is rather slow - something that you said, you don't care about .. .

I bought a Nikon Coolpix 8700 ten years ago and was extremely disappointed, also.

Although it cost me $1,000 and was advertised as an advanced amateur camera for the time, it is worthless for taking pictures of anything that moves. It has a shutter lag of about 3 seconds (in other words, about 3 seconds after you press the button, the camera actually takes the picture). Three seconds is a looooooooooong time for a picture. If your subject is moving even slowly, it is not possible to frame the shot properly. If the subject is moving moderately fast, it is not even possible to capture it at all.

I know that Nikon makes many fine cameras. But you won't find me buying any of them. I'm still angry with them.
 
^ hehe, you sound like a friend of mine. She got one of the Coolpix 7 years ago or so, which was apparently quite good. Then she got another, newer, supposedly better coolpix and she cursed the thing all the time. Now she hates Nikon ;)

Thanks for this and all the other info. Even if it gets worse than how it started, I was thinking I could crop a small section and still end up with something better than other cameras, which seems consistent with what you're staying.

Better hope the pictures are super crystal clear when zoomed in on a subject. This is an example of my camera that I did, when zoomed in all the way (Actual pixels) this is what the result is. First picture is the full picture, as you can see the color is crap I have to go through Photoshop and fix the colors and make them more vibrant.

You might want to look at the Fujifilm X-E1 or the X-M1
 
^ They've had some good feedback, thanks.
