Which cameras better? Give me some opinions.

The question is where do you plan to use it? Is it for personal, professional or freelancing? Since, there are many different types of camera.... Commonly examples are point and shoot, prosumer camera, and DSLR... Each type has different uses...so Let me know where do you plan to use it... Will recommend to you which one is better and explain you why...

I'd get Canon anytime.

If you are serious ther are only two Brands. Canon and Nikon all the rest are fighting for a disant third place. I like the Canon.

Sony has increased its market share in the last few years and is a real force in the Digital SLR market now; and in the last year, Nikon SLR sales outstripped Canon's ~ by 1% Canon has 40% of the DSR market, Nikon has 41%. THat is some achievement when you realise that Nikon had to increase its sales world-wide by 333% to do it! In the Compact market, Canon outsells the rest by 2 to 1 (Nikon has 8% of that market). What has that to do with your question? Well it just goes to show how competitive the camera market is...nobody can afford to let any other manufacturer produce a better camera or they will lose sales. Loyalty alone won't do it! So you are safe buying ANY of the top 10 brands... You need to figure out how much you can afford to spend and what features ae important to you within the price range. It doesn't sound like you are after a high cost camera like a SLR, so I suggest you try to buy a camera with a viewfinder (not just an LCD screen - they are really hard to see in bright light, they eat up batteries and they slow down flash recycling so you are lucky to be able to take a photo every 20 seconds if you have the flash on. Most reviews rate Panasonic and Canon compacts at the top of the image quality tree; Olympus makes cameras with very fast burst rates (great for sports or kids) and Pentax, Olympus and Canon make some cameras that handle rain and dust (weatherproof models). You should work out a short list and then go to a shop where you can USE the models on you list. What looks good on paper might not suit you at all "in the flesh".

I have a Sony Alpha 700 DLSR that I love. I love the resolution. I love the quality of my pictures. I take it everywhere with me. If you visit my portfolio at my profile you can see for yourself some of the pictures I have taken with it. I love my Sony but that is my opinion;-)

Digital photography is also more than just like a job or a hobby. Having an SLR would give you the best quality picture to capture while non SLR gives you the best you can do with capturing moments. Just have some reading about what you really needed for your photographs and look for those that matches your needs.
