I will be attending the IFTS in November and want to take the camera and a few lenses. Just not sure what lense or flash to use or not use. I have a 100mm macro prime, 50 prime, 18-55mm and a 75-300 mm lense. I was thinking to use the 100mm macro for taking pics of flies. Heard it is good for portrait pics but I have yet to use this lense. I am still a noob when it comes to photography so any help is appreciated. Thanks.
