Not too expensive, good quality professional cameras?

I've needed a professional camera for a while now but I'm not sure which is the best to get. I know brands like canon and Nikon are good but which type? (Like canon t3i or canon 1000d?) also, I'm not loaded with cash so cameras that are like 1000 pounds are way out of my price range. Any suggestions? Any good brands?

A great entry level DSLR (camera) is the Nikon d3200. It has an amazing 24.2 megapixels and is very light. The canon t3i is also a great model but is more expensive than the d3200. It has a flip-out screen which is an advantage over the d3200, but has 18 megapixels. If I were you, I would go with the d3200. But spend your money on lenses, not so much the camera. Hope this helps!

I would suggest you explore many alternatives- fixed lens, dslr, mirrorless. What features? Megapxls, iso, Wi-Fi. Will you take mostly landscapes, portraits, sports? A feature search or buyers' guide may help. What can you get for the price? Try this.

You can get a Canon EOS1000D with 18-55 kit lens for under £300 from Amazon

If your budget is 1000 pounds, consider about the Canon 700D, 70D or Nikon D5200 D7100. The extra money can be saved for the accessories.

Nikon D5300 --abesofmaine.com add some zoom lens and you're a great lensman!

One of the best is the Hasselblad HD-4.Might set you back
$50,000 with a nice lens or two.
For you, seriously, I'd look at a Nikon D3100 or Canon Rebel T3.

The Canon T3i and 1000D are not professional cameras. They are ordinary DSLRs A professional camera will set you back several thousand dollars.
However, both of the Canons are good models. Look at them in a store, handle them and ask questions. Then select the one that you feel happiest with.

If you think the T3i is professional and only know Canon and Nikon, stick to your phone until you know a LOT more.
