Has anyone tried using Cokin filters on the 28-105 D zoom? Does it vignette
on the 28mm end or anywhere else in the zoom range? Would a 28mm prime lens
vignette with a Cokin any more or less than the zoom? Also how do you use
flash with a variable aperture zoom such as the 28-105? Won't zooming affect
your flash settings since the lens changes apertures during zooming? What's
the best procedure for dealing with this? I use an N6006 with a Sunpak 522
flash. Since the flash is non dedicated I set my camera in manual and use
1/125 for flash sync speed and set the flash for automatic. I also use
Lumiquest bounce attachments on the flash. Any advice would be appreciated.
