Photography: Camera sensor size difference

550D then, faster AF innit.

He does pedopgraphy.

From the bushes.

Definitely the 5D then. If you did sports photography or something a 550D would be better, but the full frame sensor is better for landscapes and the IQ slightly superior.

I quite like wide angle lenses, for indoors and landscapes, would a 28mm be good enough for landscapes as well as indoor groups or is it maybe not as wide for landscapes?

Most of my photography so far has been portraits and landscapes and general documenting of life.

Is also like a 50 as a standard keep on the camera most of the time lens.

Do you think the 28 and 50 would be the best choices here or is it worth going for a zoom over both these lengths?
