I've been getting plenty of practice using my new 40D and so far it's been mostly positive.

But I've noticed something odd which I hope someone here might be able to explain.

I spend a lot of time getting the focus right in Live View of my terrestrial subject, zoomed in to 5 or 10x to really get a close-up view on the rear LCD screen during focusing. I use AF before tweeking the focus manually.

I take the shot...and then preview it on the LCD screen. However, when I zoom in to 5 or 10x I find the image on the LCD screen is soft and nothing like the sharp image I had prior to taking the shot.

I'm using a fast enough shutter speed. My ISO is normally 400...or thereabouts. I try and keep the aperture at a reasonable position for depth of field. I've tried with AF both on and off on the lens.

I'm shooting in RAW+JPEG (small).

Every time the same result.

Is this due to the resolution of the rear LCD monitor or what???

I'll keep Googling and searching the net to try and find an answer, but I thought I'd also put the question out there among the IIS Canon devotees.

Thanks
