Alright,
I don't mean to flog a dead horse, but I have to throw this question out again, because it continues to nag at me regarding my choice of lenses. I also know that most of you underwater guys probably have ff cameras and can not even answer this question. So please, any crop guys out there... have you ever used the EF-S 17-55 underwater for a shark dive or something in that nature? How did it perform? Better yet, have you used a 17-40 as well, and how did the 17-55 compare to that as an underwater zoom lens? I know that James can't help me on this one because he has never used the 17-55, so can anyone out there that has experience with this lens give me a helping hand! The only reason why I'm still nagging away on this issue is because the 17-40 will have so much redundancy with my walkaround 24-105 land lens, where as the smaller aperture of the 17-55 will open up a whole new world to me by giving me a good low light availability lens for above water use? But, how does it do underwater? Keep in mind that I'm already getting either the Canon 10-22 or Tokina 12-24 as my WA lens for general use underwater, so the 17-55 or 17-40 would only be for very select dives and I'm not planning on using it as my primary underwater lens. I was thinking either the:
1) Tokina 12-24, Canon EF-S 17-55 and Canon 50 f/1.8 = $1610 No Rebates
2) Canon EF-S 10-22, Canon 17-40, Canon 28 f/1.8 and Canon 50 f/1.8 = $1690 After Rebates
3) Canon EF-S 10-22 and Canon EF-S 17-55 = $1690 After Rebates
4) Canon EF-S 10-22, Canon 17-40, Canon 20 f/2.8 and Canon 50 f/1.8 = $1710 After Rebates
or
5) Tokina 12-24, Canon 17-40, Canon 20 f/2.8 and Canon 50 f/1.4 = $1710 After Rebates
with options 1 and 3 having a good above water, low light availability lens for indoor events like weddings, church events, or theater events, where as 2, 4 and 5 omit this flexible lens and try and make up for it through some combination of primes. But the root of any of these equations will stem from the comparrison between the 17-40 or 17-55 as a "lesser used" zoom capable lens for dives where some distance might be in effect between myself and my targets?
Thanks for the help!
