Guys, after shooting yesterday i have few questions for you. After Stalking White Egrets fishing around a lake for hours, i noticed that my pics weren't tack sharp.
Conditions were very windy though!
I focused center point AF on the eye.
100-400 mm Cannon IS USM, markins ball head, Feisol tripod. Lens was purchased in march 2009, and have really only used it handheld with IS on. Hopefully, that means a newer IS.
1) Should i be using the IS mode when on the tripod? Seems like the manual says no.
Most exposures were shot in AV mode with F stops 5.6 to 7... @ 1/500 min to 1/1600 ISo 200 depending on the light. Seems like at a high shutter speed, i would cancel the affects of any motion.
The focus is just not tack sharp. I'm using the birds eye and head area.
Seems like if i use the IS mode on Tripod, i see , and hear the servo move, and a tiny glitch.
Seems like my hand on the shutter would introduce some motion, thus IS would be good. As i do feel i'm not the smoothest on the shutter button.
I've shot some hand-held sporting track events, and the focus was tack sharp.
Just checking with the more experienced, to see what you do in regards to IS.
2) I do not know how to move a picture over here to the forums yet, as i would show a pic.
