Well ended up getting the Sigma 10-20mm f4.5-5.6, the Tamron 18-270mm on the recommendation of my photography tutor and a Nikon 50mm f1.8 which I've already used to photograph some chairs and sofas for the company I work for's website. I also invested in a SB700 flashgun
That will do me for starters, but as time goes on I will look to both add and upgrade as funds allow. The only difficulty is that with so much choice it's a minefield trying to narrow down my options when choosing new lenses.
