What kind of professional camera do you suggest?

I'm looking into professional cameras lately to price them and such and was wondering what kind you would recommend. I'm looking between Canon and Nikon, but Canon seems better at the moment. Also, I would like one that the lenses can be changed to suit a certain lighting, setting, etc. I pretty much am looking for one that could be used for professional use if I were to become a photographer full time.

Both Canon and Nikon are excellent cameras. It comes down to personal preference. Which one feels better in your hand and where the controls are more natural. I have been shooting Canon for 20+ years, so I can pretty much pick up any Canon and I know how it works. With a Nikon, I need to think about how to make adjustments and what to press…

Once you get a camera, the real money is in the lenses. In general, the kit lenses that come with the cameras are not very good, but they are OK to start out. I have $1, 000s invested in lenses, so in addition to having a better feel for Canons, I would never switch to Nikon because I would have to repurchase all those lenses. I can upgrade the body of my Canon any time and still use the same lenses, but but has to be in the same family.

Are you sure you want a pro camera? A pro camera with pro lenses is going to start at around $6000.00 I'm betting that you do not need this kind of camera simply by reading your question. I suggest you get a body like the Nikon D3100 and if you have the money, start buying pro lenses. Bodies will become outdated but the lenses will not. Buy a 70-200 f2.8, a 50mm f1.4 and then a 28mm f2.8 and you are set. Buying a pro body right now for you would be a gigantic waste of money.

Nikon D300s, Nikon D4, Canon 5D, Canon 1Ds MARK III

I assume by "pro" camera, you mean a DSLR in general. A pro DSLR can be very pricey.

Both Canon and Nikon are excellent and are the top brands for pros. However, many other brands also have excellent cameras - Sony, Pentax, Olympus, etc. My preference is with Canon, as that is what I started shooting on when I bought my first camera.

A good few choices for entry DSLR are:
* Canon T3 - 12MP, 2.7" LCD viewfinder, good ISO range, and 3 frames per second burst mode - probably less expensive than most other Canon DLSRs
* Canon 60D - slightly higher end, with 18MP, video mode, 3" LCD viewfinder, and 5.3 FPS. A tad more expensive in the DSLR series.

There are also some middle models between these (T3i, T2i, etc), which have various features,

You should assess what you are looking for in terms of features and how you will use it, and match those to the camera.

How this helps.
