yongfei Posted July 25, 2000 Share Posted July 25, 2000 I looked at the lens section of this site. But the MTF concept is too complicated for me to understand. I downloaded some MTF charts from http://www.zeiss.com website. I try to compare the MTF between 80 CB and 80 CFE. Could you explain what is the ideal curve (diagram 1 and 2, k=2.8, k=5.6) in this case and from the curve, could you tell approximately how much better is the 80 CFE lens? I know that a purchasing decision based on MTF is not good. But just want to know something basic about MTF since the information is available there. Thanks!

greg_erker Posted July 26, 2000 Share Posted July 26, 2000 photodo.com has an explanation of MTF charts on their web page. It might be of some help to you. Link to comment Share on other sites More sharing options...
yongfei Posted July 28, 2000 Author Share Posted July 28, 2000 Thanks. That's exactly what I'am looking for. By the way, several months ago, I bought Earnest Wildi's Ultimate Image, trying to know the tricks of obtaining the best image. Although that book teaches some basic amateur stuff, It really doesn't fit the title well. Photodo.com is the site I will be very passionate about. It delivers! Also, I somewhat feel regret that I bought the Nikon gear in 35mm. It seems that Contax offers better image quality. Link to comment Share on other sites More sharing options...
