Hi everybody! First post! I've been lurking around for a bit and cant seem to find the answer I'm looking for. I recently purchased a T1i for a trip to NYC/DC and pretty much got hooked on photography, I've been asked by my boss to take pictures of the buildings that we have completed and the future buildings that we are in the process of completing to build a portfolio for our General Construction company. My camera came with the 18-55mm kit, and the 55-250mm kit. I love taking pictures of architecture/landscape and if I have the opportunity to have the "company" expense me for a lens what would you guys/gals recommend? Wide angle ? Fish Eye? do I need a tripod? So many questions... sorry this "hobby" can be overwhelming. Thank you in advance for your advice!
