ryee3 Posted July 27, 2010 Share #1 Posted July 27, 2010 Advertisement (gone after registration) Recently I read on another Leica forum the the following combo will work for taking telephoto photos. Has anyone had some experience with this concept of combining the 2 extenders on a 280mm f2.8 lens? Will this work and is there some loss of image quality?

grduprey Posted July 27, 2010 Share #2 Posted July 27, 2010 I believe it has been done before and it works pretty well, but there is a minimal bit of loss, but not enough to worry about. Now if I only had one of these lenses and either of the extenders. ;-) Link to post Share on other sites More sharing options...
wildlightphoto Posted July 28, 2010 Share #3 Posted July 28, 2010 I've combined the extenders with the 280mm f/4 APO. There's a noticable loss of image quality, but the biggest problem I had with the combination is that the focusing ring's pitch becomes too "steep", making precise focus very difficult.
