EOS Bodies / Canon 60d unavailable on BH and Adorama
« on: December 28, 2011, 05:15:55 AM »
I just noticed that both BH and Adorama list the 60d as out of stock ? What can this mean?

Canon General / Dynamic Range - Digital sensors
« on: November 08, 2011, 08:49:03 AM »
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?

Canon General / 50mm Focal length for portrait
« on: November 02, 2011, 02:40:03 AM »
Can good portraits be taken at 50mm (eq) ? I use a rebel and find that for head and shoulder shots taken at about 4 feet away from the subject, 35mm seems nice. (35 x 1.6 = 56)

Does this contradict the long standing notion that you need a 100mm (eq) for a good portrait ?

Canon General / Photography - Equipment or Skill ?
« on: October 02, 2011, 07:38:06 AM »
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 ?

Canon General / Improving composition - photography skills
« on: September 25, 2011, 09:00:48 AM »
Dear All,

Pardon me for interrupting the flood of tech - equipment type posts. I would like to ask those of you who are seasoned photographers a question about PICTURES (not cameras) for a change.

I am an amateur photographer (as a hobby) for about 14 months now. I started out right at the bottom coming from simple p&s pics at a birthday party - and I'm trying to improve my skills.

Can you suggest some tips on how to advance my composition skills ?

Canon General / Autofocus Problem / Question
« on: September 19, 2011, 03:45:32 AM »
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 ?

Thank you all

Lenses / Lens recommendations for t2i crop sensor
« on: July 10, 2011, 07:26:35 AM »
Hi,

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 ?
