Your feed back is appreciated. I have started to use a tripod for virtually all landscape photo's now if at all possible I have also started to use the mirror lock up feature and I use my wireless remote to fire the camera or the 2 second delay feature. I also turn the IS off when the camera is on the tripod. All this is an attempt to keep the camera in a vibration free environment.
I typically always shoot in AV mode and at 100 ISO if at all possible. Longer shutter times are not an issue when on the tripod. I also activate the long exposure noise reduction feature.
I also use a good polarizer or a variable neutral density filter depending on the shot.
Hard to say if anyone thing is the answer, but in aggregate I think it helps to get the very best IQ the camera is capable of.
No prob. Almost same here. I shoot AV mode as low as 100 ISO accept if it is windy I will bump the ISO to 400. Also use my remote and cpl when needed. I have to check mirror lock up never use it before.
