Does anyone have experience or know where I can get quality non glare glass or glass film to help in copying large old record books? Any that I have tried show reflection of copy stand and lights. Thanks in advance for any help.
Isn't crop factor still a consideration with the EF-S lenses?
No...an EF-S lens on a crop body is "what it is..." no multiplication involved. :)
I not sure where many of the contributers here get the impression that EF-s lens no not need the crop factor applied. ALL lens are in mm and if its a crop sensor camera you need to apply the factor mo mater if it is an EF or and EF-s lens.
