Stefan,

 

Hallelblad rated the Canon 28-70/2.8L lens as the sharpest zoom lens ever made (sorry, can't find the reference. I read this when researching the purchase of this lens about a year ago.) This said, if your images don't appear sharp to you, it should not be the lens's fault. It is an extremely sharp lens. I assume you are not hand-holding, since your stated goal is sharp landscape images. The 28-70 is quite heavy, and is not one to hand-hold anyway, never mind landscapes. As far as Canon lenses go, for this coverage I would stick to the zoom, assuming the one you own is not faulty and producing unsharp images. Although it is true that good primes tend to be sharper than good zooms, this zoom should hold its own.

Alex, by now you might have figured out the answer to your question.

If you have not, I think that by your explanation of "three flashing

blocks", you are confusing the bracketing of exposures with the

exposure compensation. I could be totally wrong, and if I am I am

sorry, but the only time I can think of the exposure compensation

markings flashing is when only one or two of a bracketed exposure

have been taken. By switching the camera setting, as you mentioned,

this would turn off the bracketed exposure as well, thus stopping the

flashing marks. Just a thought, hope I have helped out. Rob

I have had the pleasant opportunity to shoot for the last few days with a friend who shoots semi-professionally with Canon equipment. My friend has the new 500f4/L IS lens, and I noticed she does not use the IS function very much. My primary lens is the 300f4/L IS lens, and I almost never use the lens without the IS functin turned on. when I asked her, she said the image floats in the frame and bothers her, so she does not use it much. I used it today, and to my surprise, the image did float slightly in the frame, as if it were slippery.(this is the only way I can think to descdribe the appearance of the 'float') The image would slide around slightly without any noticable consistant direction. I would like to purchase one of these lenses, and am VERY concerned about this problem. Has anyone experienced this or heard of this problem?
