Hi all,
Currently I own a F70 with two Sigma lenses. Thinking of upgrading to a DSLR. Just wondering if I could use my old lens on the DSLR. If so what is the difference between a lens meant for DSLR and a normal lens. Will the picture quality degrade between the two lenses? If I will want to invest in a 17-35mm lens now, should I get a normal one or the one with SLD? (there's a huge price difference) :sweat:
Below was abstrated from sigma website.
" Designed to suit the special characteristics of digital cameras
SLD (Special Low Dispersion) Glass is used for effective compensation of color aberration. Two pieces of molded glass aspherical lens elements offer excellent correction for distortion as well as all types of aberration. It is an ideal lens for Digital SLR Cameras as well as film SLR cameras. "
Does it means that using a normal lens on a DSLR will cause distortion in the pictures? Any one has any pictures taken with a normal lens on a DSLR and one taken using the SLD lens for me to compare? :dunno:
Thank you for your time and best regards,
Linus
