A Modern Classic
You Don't have to spend a fortune to get a great image. If your main hope is for fanastic image quality outdoors and if your willing to settle for lower dynamic range or high ISO performance there are a number of fantastic choices for photographers looking to start out in the world of full frame cameras.
The Canon EOS 5D was the camera that started the full frame revolution, it has a reputation for amazing colours at low ISO and a natural feel to the images from it's 12 (ish) megapixle Sensor and on top of all that this is by far the cheapest full frame camera available. If you are willing to do a little searching on ebay I have seen examples for under £200.
The Not So Good
I consider this camera unusable for colour images above ISO 800. Above that Black and white is really the only option and ISO 3200 should be used with extreme caution. Dynamic range reduces dramatically as you increase ISO so if you can help it at all you need to stay at ISO 100-400. The auto-focus is also legendarily bad with only the center point being usable in anything but perfect light.
The sensor resolution is not up to printing high quality large prints at anything but the lowest ISO settings.
Who should by this?
Photographers that want natural images and a stepping stone into Canon's fantastic lens line-up. Paired with a 50mm 1.2 or the amazing Sigma 50mm 1.4 this camera is unparalleled in terms of image quality in good light.
If you treat this camera like a 35mm film camera, taking care to shoot in good light and are happy to have a romantic grainy black and white look at high ISO this could be your perfect camera.
