I'm slowly building up my lens selection on a budget, simply as I'm still not sure where I want to plough big money into yet and which area is going to be my focus (pardon the pun). Started with the 400D 18-55mm kit lens, added a Canon 28-80mm USM lens from eBay shortly after. Now I've snapped up the ubiquitous Sigma 70-300mm APO off a mate for an even ton, to give me more reach. I'm gonna have a spare bit of cash later this month, and I want to again add something modestly priced to flesh out my collection further and give me some additional shooting options. Now I've had my eye on the Canon f1.8 50mm lens for ages based on the good things many people say about it (based on it's titchy pricetag), and I could add a few extra bits to go with it (maybe a grip) with the money left over. Or, I could buy the modestly priced (but again positively spoken about) f2.8 28mm wide angle from Canon for around the £150 mark. I need help making my mind up. Any clues? I'm mainly into outdoors photography, so would the 50mm be a bit useless? Anyone else buy the 28mm? I'm still learning so excuse my ignorance.
