The Canon 5D, from "Steve's Digicams" review

This paragraph:

"The 5D is the first moderately-priced dSLR with a full-frame image
sensor, eliminating the crop factor or focal length multiplier that
has made wide angle shooting difficult with dSLR's; the Canon EF
17-40mm f/4 L has an effective focal length range of 17-40mm on the
5D! While this is great for photographers who rely heavily on wide
angle lenses, it will not be welcomed by sports shooters who have
enjoyed having an effective focal length of 640mm from their
20D-attached 400mm lens. "

So, the implication is here that a cropped format camera doesn't
simply show a smaller "area" with a given lens, it also produces
a greater telephoto effect, in essense showing details that
the FF camera would were it equipped with a lens of the same
equivalent focal length??
So a 400mm lens actually becomes a 640mm lens because of the cropped
focal ratio?? The myth is TRUE!!!!!!

Further to the statement:

"-The 5D's telephoto shots can cropped in an image editor, but to
realize the same effective focal length as a 20D, the 5D's cropped
image would be left with only about 5-megapixels of resolution."

 

Yawn...
No, Rich, and even you don't believe that.

 

I was just hoping! Imagine a sensor, a couple mm's square, with
1.8um pixels. Converting a 100mm into a 500mm lens!!!!!
Talk about power and resolution in a small package!

Well, it is a long established fact, "There's no such thing as a free
lunch!"

 

Why don't you talk about your total failure to understand digital
photography?

 

I guess, in a sense, he is doing exactly that.

 

I'd rather talk about your inability to recognize truth from fiction.
