<p>I would like to upgrade from my old Digital Rebel XT DSLR which I've had for 10 years. Other than a standard kit lens, I have been using a 50mm 1.8 prime lens, so I guess I'm not hugely invested in the Canon system</p> <p>I would like to upgrade to a full frame camera and purchase some better zoom lenses, I'm thinking perhaps 70-200 f2.8 and 24-105, both possibly in Tamron/Sigma form rather than Canon</p> <p>However, I'm stuck on the body. Looking at the 6D, seems quite old now and it seems Nikon seem have more modern versions and choice in this price bracket</p> <p>Ideally I would like to upgrade within the next week or so as holidays coming up, I appreciate the 6D is due upgrade next year but don't think I can wait that long</p> <p>I would be grateful on advice whether prudent to switch to Nikon for the better choice of full frame cameras particularly at the 6D sort of price point or any Canon suggestion</p> <p>Many thanks</p>
