Hey everyone, I'm having issues nailing down an answer to the problem of using my Lee Foundation system on my soon-to-own more portable Olympus camera and lenses. My initial kit is looking like it will be an Olympus E-P5 (in the mail), 12 f2 (here), 17 f1.8 (in the mail), 45 f1.8 (here), and 75 f1.8 (currently convincing the wife). So, what's the best way for me to get the Lee Foundation holder/filters onto these lenses? Is my best bet to get the 58mm Adapter Ring here: LEE Filters Adapter Ring - 58mm - for Wide Angle LensesWAR058 and then use step-up rings for the 12, 17, and 45? Has anyone done this with the 12 or 17 and seen vignetting issues? I know there's another filter system made by Lee that covers mirrorless cameras but I'm not going to drop another few hundred dollars when I already have a lot invested in my current setup. Thanks in advance for any help you all can offer.
