If you haven’t releasized it, polarizers and neutral density filters are a must. I use to carry my filters around in a bulky soft pack case. The case took up a fair amount of space and provided the minuial aoumt of protection. I was re-reading Art Shaw’s Lanscape Photograpy book and discovered that he used something called StackCaps for carring his filters. I then seached the web for this must have item and found some on Kirk Photography, Kirk makes fine equiptment and great to deal with but they cost just a little to much for my budget. I then went to ebay and found another vendor who had some inexpensive ones. So I bought a couple through his buy it now auction and are very happy with them. There stack caps are first class, heavy aluminun and nicely machined with a nice black anadized finish. The company is named HEAVY STAR. Here’s a link to there store. http://stores.ebay.com/Heavy2stars-Photo-Gear
