I have an engagement coming up in July and I would like to take the best pictures I can with My T3. It's for a 80th birthday and will be held in one of the officer clubs, so the lighting want be great. Currently, I have the standard lens that comes with the camera and a 55-250mm f/4-5.6. I plan on ordering the Canon Speedlite 90EX & the Canon EF 50mm f/1.8 II in the next couple of weeks. Money is limited, but should I substitue something else in place of the Canon Speedlite 90EX & the Canon EF 50mm f/1.8 II?
