Hi all, need your guys comments on this.
Have read up some materials in the web regarding these 2 filters
"These close-up lenses obviously signify a working distance of up to 250 mm and are recommended for use with lenses in the 50mm to 135mm range (maximum filter diameter available is 58mm). The 500 lenses are recommended for lenses in the 70mm to 300mm range."
I wish to get a similar one for the 135mm f2L lens. Should I then get the 250D or 500D? Any diff besides the magnification? Or any comments on this setup?
Thanks in advance!
