Allen's Camera Levittown,Pa.
With regards to Lee.
You have to get the lens adapter for each lens of a different size. (If you use more then one lens.)
I got a half dozen Lee filters from Allen's but almost everything from Lee is back ordered.
You just have to check around to see what folks have.
Thank you Dan! However, I'd already checked with all the dealers you've listed above and none of them had it in stock. And neither do they have an estimate of when they will get their next shipment. Seems to be more manufacturer related than anything else. What's funny is they seem to have the adapter in stock while the kit is out of stock. I'll keep looking around. Thanks again!
