Quality always suffers with the higher ISOs, but it wasn't as bad as i thought it was going to be before i started using it regularly. The higher ISOs on the SLR are porcelin compared to the same higher ISOs on my G9. The Haunted Mansion shots i maxed out at 3200 (not available on the G9). The quality didn't bother me so much because i needed to be in that 1/40 or faster range.
Thanks for more great shots, Ivankay. The 1.4 is the way to go for Haunted Mansion shots. Even with the ISO boosted, it's still pretty tricky to get ANYTHING decent in there as you are constantly moving and bumping around. GREAT job on getting those clear shots!
