Now I have become the very proud owner of one of these lenses I have a question about it.
On my other lenses, when the AF is on and the camera acquires focus the relative focus points flash momentarily in the view finder to show where focus has been achieved, and on the camera when you review the image its possible to see what auto focus points achieved focus as they come up as red squares on the image. With this lense this doesn't happen, no flashing autofocus points in viewfinder and when you review the image all the AF points show up as red. Is this normal ???? Focus seems to work OK. BTW IS was switched on in mode 1.
Thanks in advance
If you want to edit any of my images to demonstrate points/techniques to either myself or others please feel free to do so.
Still learning with Canon 40D, 28-135mm, 100-400mm L and Elements 6.
Any Advice greatfully received.
