I'll be at Montréal's F1 Grand-Prix in a few weeks and I'll be shooting some of it. I've been there a few times before and shot with various crop bodies and lenses combinations . For photos of the cars, the seat I have allows access to at least one good photo spot. I own the Canon 70-300 F4-5.6 IS and never really liked it. Moreover, it is too short getting anything but the closest corner and pit exit. (I actually wonder why I still haven't put it for sale...) Last year, I rented the 100-400L and really liked the lens a lot. However, I would have liked a bit more reach for getting some additional point of views. Therefore, I was having a look at renting a Tamron 150-600 or Sigma 150-500. Now here are the questions I have:
1 - Does anybody knows of somewhere to rent the Tamron in Canada? (I haven't found any by googling around...)
2 - If I can't find a Tamron, would the Sigma offer anything better than a cropped image from the 100-400?(remember I already shoot a crop body - 60D - so I may already be pushing the envelope...)
Note: I can rent the 100-400 or Sigma for about the same amount.
