This is a vintage 49mm 80B lens filter from P.R.O (Photographic Research Organization Inc, NY). It comes in its original plastic case, and is boxed in its original printed box. The filter is in fair condition with no scratches but the glass is 'fogged', hence the price. The metal rim is unmarked. The plastic case has very little wear, the lids fits and holds well and the case still has its soft interior base padding for protection. The box shows signs of age and has a tear to the reverse.
The 80 series filters are bluish in colour, with the 80B being slightly more intense than the 80A, or the 80. Blueish filters raise Color Temperature to correct yellowish tungsten (incandescent) light to match daylight film and thereby produce neutral results.
Please note: As stated the glass is 'fogged' and may affect its usage.
This P.R.O 49mm 80B filter will be sent well packed and promptly. My postage charges are very fair and I do not make money on shipping.
I am new to Etsy after having been a seller on eBay (and before that Yahoo Auctions) for many years with a 100% rating of well over 2000 sales. I specialise in cameras, camera lenses and filters and other camera gear, but I will also add other vintage items over time too. Thank you for looking :-)
