I see that Practical Photography mag has put the Sony a700 on top in a head to head test with the Nikon D300 in their April issue.
In their conclusions they went on to say that the Sony produced almost identical results as the Nikon and so in the end it came down to value for money with the a700 moving ahead due to it's price.
Looks like Sony could be a major player in the DSLR market pretty soon with reviews like that.
Opinions?
