I have booked a hot air balloon trip in May and am already trying to decide which lens to bring - I only want to bring one up with me. Does anyone have any experience of this type of photography? I have an XTi/400D. My lens options are 17-40L, EFS 18-55, 75-300, 100 Macro USM, 300L. I'm pretty sure it'll be the 17-40L for IQ but will I miss the extra reach of the other lenses? Thanks in advance for advice.
