Question: Can someone please explain why digital sensors have a much narrower dynamic range then film ? This is apparent to anyone shooting outdoors in bright light - the shadows are black and the skies blown out.
Will digic 5 improve this? Is it possible to improve it?
We spend allot of time here comparing equipment and extensively analyzing the pros and cons of bodies, lenses, etc.
However - many people say, that the real ingredient for producing special pictures - is the skill of the photographer. Many all time famous monumental photographs where taken black and white with "simple" equipment. The special part of those photos is often the content and meaning of the picture - much less the "sharpness" or other tech features.
How important is our equipment ? Would you agree that it more like 85% skill and 15% equipment ?
This is for those of you who have deeper tech understanding of what goes on inside the camera:
Question that is bothering me:
I have a rebel 550d (t2i) + canon 50mm 1.4 prime. Even when I try to carefully focus using the center focusing point only (which is supposed to be most sensitive) the prime often "just" misses and the picture is slightly / moderately blurry - depending on how wide I opened the lens. 1.4 - 2.5 are almost always slightly off. It does not seem to be a back/forward focus problem - just lack of capability to achieve sharp focus.
If I focus using the sensor in live view mode - the focus is almost always tack sharp - or at least much better, even wide open at 1.4 - and beyond 2 tack sharp.
1) Can someone explain this phenomenon? 2) Would a more advanced body (say a 60d ) have better autofocus results ? Is there a difference even using the CENTER focusing point between the 550d and the 60d ?
I have a t2i with 15-85 kit lens. The 15-85 is nice as a walk around - but a slow lens in general, and I'm very much missing a faster option. I tried the canon 17-55 - seems very costly( >$1,000!) and bulky for medium build lens. My auto focus was not tack either....
Any ideas ??
is there a way to calibrate auto focus on a lens - without messing the body up - and causing it to miss focus on other lenses ?
