Cheap is the word...when you buy a cheap alternative, you get an alternative to good pictures!!! ;-)

I bought the filter set online of Opteka lenses, which included UV, Flourescent, and a Polarizer. One thing I don't like about them is that I have to zoom just a little while using the polarizer or else the corners of the photo has just a little itty bitty bit of the lens in there. Sometimes it doesn't focus correctly with the Polarizer but most of the time it does great. I give the polarizer a 8/10. The flourescent filter does great. I would take some pics with and without to show you but it since it's morning I don't have the correct light I need to show how effective it is (morning sunlight isn't right for this). 10/10 for the flourescent. The UV, well it does fine, not much to say about it except I keep it on my camera and never take it off.

I am getting in a pair of Wide angel and Tlephoto lens from Opteka this thursday, So I'll be sure to post my reviews by this weekend on those.

Sorry if this is OT, but what shutter speed works at 400mm, at 800mm (35 mm equivalent)? Assuming AS (or IS) as in Pan. Z10 or Minolta Z3 / A2? I assume w/o AS at that range we are always talking about a tripod?

Thanks.

It would probably get better response and more interest in its own thread, but the basic rule for handheld pictures (without IS) is you set your shutter speed to at least "1/35mm equivalent focal length". If you zoom to 400mm, set the shutter speed to 1/400th...considerably less and you should use a tripod or other steady surface. I've taken handheld shots at 1000mm, but my shutter speed was 1/1000 to compensate (of course if you don't have steady hands, you wouldn't be able to acheive this).
