Now that HDR or HDRI is becoming more popular I thought it would be helpful if people could have a place to talk and help each other out with this challenging, yet exciting style of photography.

35mm vs DSLR Lens

Posted on November 1, 2011 at 2:40am 5 Comments 1 Like

As we know the crop factor of the sensor is multiplied with the Focal Length of any DSLR Lens. Example 24-70mm of DSLR is equivalent to 35-105mm of 35mm assuming a crop factor of 1.5.

But on the reverse if we attach an existing 35-105mm aperture 3.5-5.6 lens of 35mm film camera over a DSLR with crop factor 1.5, then, WHAT HAPPENED?

What would be the focal length and what would be the aperture value?
