I have just been commissioned as a replacement for Life Touch for a massive panorama with about 1700 students. I think that is a bit much to ask of my Canon 5D. However, I was thinking about dragging out my 8x10" with a wide lens. I will have to rent a wide angle since I only have a 12" lens. I also have a 4x5" with an 88mm. I am not sure what to do since the shoot is on Monday.
