My current full frame lens inventory is the following:
- Canon EF 8-15mm f/4L USM Fisheye
- Canon EF 50mm f/1.8 II
- Canon EF 70-200mm f/4L IS USM
- Canon EF 400mm f/5.6L USM
- Canon EF 100mm f/2.8L Macro IS USM
- Canon TS-E 24.0mm f/3.5 L II
- Carl Zeiss Distagon T* 35mm f/2
Of those, I'm planning on taking with me only #'s 1, 2, 3, 6, and whatever UWA I eventually get my hands on. Yes, I've always been lacking in the 24-70mm range zoom wise, but I've managed because my work usually requires me to work with setups and primes (I'm not a photojournalist).
Based on the course content description, architecture and urban planning is a chief focus, but I don't expect to have the time to carefully set my tripod and level and use my TS-E to make perfect pictures of buildings. We're s'posed to be on the move most of the day. I'd probably be taking only the WA, the normal (failing to have a zoom for the 24-70mm range) and the tele, and leave the specialty lenses behind for the weekend, when I've time on my own.
Rental is not a very attractive option: no rental places in town, which means I have to arrange and pay for shipping, plus the rental fees and deposit. At the end of the day, I'd rather put the money towards a brand new lens that I can keep forever.
