I have a diy flash bouncer made of aluminum foil and wire hanger which I use for my pop up flash. It reflects light to the ceiling and I really like how my photos came out so I have wanted an external flash for that. However my primary lens is a Canon 18-55mm f/3.5-5.6 IS and the Tamron 17-50mm f/2.8 will be beneficial for better quality/low light condition.
What do you recommend?
