Out of curiosity, where does the 1.5x come from? I know there is a difference between DSLR and regular 35mm SLR is that what you are referring to?
come on mike. read up.. wish i typed.
google search ''1.5 lens factor''

No need to get harsh. That's what I figured you were talking about. For whatever reason I didn't even think about it translating to the lens like that. Thanks for the info.

Mike-

I made my explanation very simple and there was nothing harsh about my post.

Sarah, it wasn't your post I was referring to. As a matter of fact, I didn't even see yours.

So does this also factor in with the DSLR lenses like the 18-55mm kit lens?

That's ok, I probably could have worded the question a lot better. I already knew about the crop factor, just didn't really think of it factoring into the specs of the lens like that. Just wanted to make sure. No harm done. :lol:

the ''made for digital'' lenses are still rated at their 35mm equivalent. so the kit lens is actually a 27mm - 82.5mm. why??? go figure. i don't know!! the DG lenses won't even work on a 35mm body. well, they will but all the edges will be dark due to vingnetting..

They are really what it says on them, 18-55 and 50-200. BUT since the CCD sensor is smaller than a traditional negative, when enlarged to a copy they give you the effect of a lens that is 1,5 times longer than if the same lens is used on a traditional film camera. So it gives you pictures AS IF they would have been 27-82.5 and 75-300 on a film camera.

Mostphotographers use this "old" measure because they are familiar with it. Compare with horse powers, it made sense when most people could refer to the strenght of a horse and wanted to know how strong the car engine was.

Good point, Kjell-

That is an excellent explanation of something that we have to deal with and explain rather often.
