You can get a new Nikon D750 and 24-120 f/4 lens for under £1500 at the moment But As others have said, it is very important to try before you buy. How soon do you wish to take the plunge and get your kit? Where do you live? There is the SWPP Show in London next week-end, where many of the major manufacturer'#s products will be available to try during the trade show, and then in mid March at the NEC, the Photography Show where there will be an even larger amount of kit to try out and buy at often special low prices. You need to decide what is important first - full frame, APS-C, micro 4/3rds or whatever, then if you want a zoom lens or a prime or two. Will sheer size and weight be an issue? What about ease of handling and adjusting parameters such as ISO and shutter speed? Don't rush into making a decision !!
