Hi,
I currently have a Sony a330 and have been looking to upgrade to a model with more features and better resolution. I have also been looking to increase my lens collections, currently the 18-55 kit and 70-300 Tamron lens.

Before I began to spend more money on Sony fit lenses I was trying to work out which camera body to go for. Sony don't seem to have an obvious choice. The a580 seems to be comparable to entry level Nikons and Canons so I assume will not give a massive advantage. I therefore started to look at Nikon and Canon and what they had to offer. The Canon 60d seems to be a favoured option.

The question therefore is, should I move to a Nikon/Canon with more obvious upgrade options before investing more on a Sony system, or should I stick with Sony? Will the swap over cost be worth the benefits I would receive from a new brand?

Thanks
