Hello everyone. This is my first post here and I need help. I'm just about at my wits end.
Well the new lenses arrived a few weeks ago. I anticipated having my socks knocked off but instead when the lenses saw first light, I was not so happy. I took both lenses outside and shot some landscapes with trees and clouds as well as some photos of squirrels. When I went back in I found the following:
17-40mm f/4L: The edges of the clouds were not sharp at all despite well defined edges being seen when I looked though the viewfinder when I shot it. The leaves on the trees seems to have ghosting as if there was camera shake or motion blur (there was no breeze and the shutter speed was over 1/1000s). Items with hard edges like fences or trees, were not tack sharp - not even close. I did tests at both 17 and 40mm at different iso's and f stops. The usual f/8-f/11 sweet spot didn't seem to do anything. The color the lens produced also seems weird. I took a photo of a brilliant sunset and when looking at it in RAW the color was very muddy and flat. I also used a 50mm prime and 15-55mm kit lens to shoot the same sunset in RAW and sharpness and colors were brilliant.
100-400mm f/4-5.6L: I was expecting to see whiskers and hair on the critters I took photos of instead they were all blurred. I even had my dog sit about 50 foot away in bright light and took photos of his face. Again the hair and whiskers are not sharp despite the photo being in focus. I tried several things, hand held, IS on, IS off, monopod, tripod, tripod with cable release, tripod with cable release and mirror lockup. I kept getting camera shake or soft focus. I got ok results with the monopod and IS on and better results with the tripod and IS off but this was also at noon, in bright light at ISO 800, f8 and 1/500s. This combo resulted in usable images that were in my opinion printable. Results also seemed hit or miss even with the tripod. By the way, my tripod is a heavy duty model - it was over $500 so it's not flimsy.
Thank you so much!
