Lens for Product and Corporate portraits
I have Canon 600d and Canon 18-135mm + Tokina 100mm Macro lens with me. I have done some initial Corporate Portrait shoots (Torso or head shots - lighting mostly provided at the shooting location) and product photography (jewelry, small products, or clutches purses - I have a box studio setup with me) using these lenses, esp. 18-135mm.
I want to know should I continue using these lenses, or do I need to purchase a new one? Any recommendations? Typically I use AV mode since it makes my work easy and rest of editing is done in Photoshop.
Just to add - I do not want to go into wedding / pre-wedding or candid, since I have lot of pro photographers in my city / known circle and is hectic due to my other commitments. I am targeting corporate shoots (still/video), product photography for eCommerce or offline purpose, and industrial photography.
