Hey all, after buying my K20D I'm looking to save up for a new lens (tamron 17-50 f/2.8), but now I'm thinking about getting a flash unit instead (http://www.twenga.co.uk/prices-AF-540FGZ-PENTAX-Flash-units-120195-0).
Reality is though, I havn't a clue which I should get first. I know I'll end up buying both eventually, but what should I buy first? What will be more beneficial without the other? I'm thinking that with a flash unit I won't have an immidiate need for the f/2.8, but in low light situations where I don't want to use a flash, I'll want the f/2.8, rather than having to sit at 18mm with f/3.5, since shooting at 55mm at f/5.6 won't be much good.
What would you personally buy first, and for what reasons?
