In 2001 Super Bowl XXXV's halftime show was performed by Aerosmith, 'N Sync, Britney Spears and Nelly. The show was probably shot with the ultra powerful (for its time) Nikon D1H which had a 2.7mp sensor and was said to create "very usable images at ISO 800." Yesterday we had Madonna and LMFAO perform and their show was photographed with the Nikon D3s (which is now also out of dates) which has 12mp and shoots similar quality images at ISO 12,800. Isn't it interesting that what was considered "professional" 11 years ago can now be outdone by consumer level DSLRs.
If you guys can find examples of 100% crop images from the Super Bowl then and now I will post them.
