View Full Version : Promaster Spectrum 7 1A does...?
9th of May 2011 (Mon), 13:17
I recently bought a lens with this Promaster Spectrum 7 1A filter on it. From what I understand its a skylight filter or something. It is also my understanding that there is no use using this on a digital SLR apart from physical protection of the lens itself. Am I right?
Also are these filters made my Hoya? Also what would the value of this filter be assuming its in excellent condition?

Yeah - "Skylight" (very faint pink) filter; 1A is the Kodak Wratten designation, widely used in describing filters. It may, in extreme UV conditions, help supplement the sensor's UV filter. Hoya, B+W and Heliopan also make 1A filters, but I wouldn't know who makes the ProMaster line; maybe Tiffen - they are reputed to make filters for a number of other brands. As to value, depends on the size. 52 mm (I'm guessing the filter was on your new 50 f/1.8) seems to be running around $10 on eBay.

Thanks for that info! Yep its a 52mm and it came on my "new" 50!
So this filter could be made by either Hoya, B+W or Heliopan? Whats Promaster then? I read somewhere that Promaster was made by Hoya which is why I asked. And if they were made by Hoya how come they don't say Hoya on them :p

Hoya, Heliopan and B+W also make Skylight filters. I have no idea who makes Promaster, but Tiffen seems a likely bet since they make filters that a number of other brands market. Quantaray and Canon are two they are reputed to make (and neither Quantaray nor Canon filters are all that good).
