m_duong Posted July 3, 2007 Share Posted July 3, 2007 [identification] Tristar 1A 55mm Japan I bought a Canon FTb QL, a Sears Multi Coated 1:40 f=80-200mm auto zoom lens, and a Sunpak auto 231 flash for 70 dollars. I didn't ask the guy I bought it off of what kind of 'filter' is on the lens, and I don't get to see him for another month... The lens has a 'filter' of some sort that I cannot identify. This filter in question has "Tristar 1A 55mm Japan" written on it. I've searched google images to find that usually they have their identify mark written on there (a polarized filter would say 'POLARIZED'). My questions are: what is this filter? and should I keep it on my Sears lens? Any other tidbit advice would be helpful. I'm testing out the camera today and any feedback would be greatly appreciated.

alex_lofquist Posted July 3, 2007 Share Posted July 3, 2007 Is this a light red filter? If so, take it off as it was intended mostly for use with cloudscapes to bring out the detail in the sky. Also check the filter to see if it is heavily scratched, stained or pitted. Discard if damaged. Link to comment Share on other sites More sharing options...
m_duong Posted July 3, 2007 Author Share Posted July 3, 2007 Hi! Thanks for the feedback. Sorry for the poor filter knowledge, I had to google image search a light red filter to match that up with what I remember from years ago. In reply to the light red filter, I do not think it is a light red filter. It's transparent filter. It might have a pink rim, or the ring that holds the filter has a red-pinkish rubber set in a groove. As to the condition, it has minimal stains.

JohnMWright Posted July 3, 2007 Share Posted July 3, 2007 This appears to be a skylight filter. "1A" is the filter type. It is basically a UV filter with a very very slight warming effect (most of use wouldn't notice the effect I think). I'm not familiar with the brand Tristar, but I'll guess it is a fairly cheap filter. If the stains don't come off with a careful cleaning then I'd throw it out and get a new one (if you choose to use filters). Link to comment Share on other sites More sharing options...
jimstrutz Posted July 3, 2007 Share Posted July 3, 2007 Yep, Tristar filters are cheap, and 1A is a nearly clear UV type filter. 55mm is the diameter of the filter threads. They used to add them to "kits" to make the buyer feel like he got some added value to his package. It's worth nothing. Link to comment Share on other sites More sharing options...
