I will soon purchase either the Fujinon TS1440 or the Nikon 14X40 (both image stabilized units). I feel uneasy using these in marine environments without some sort of filter in front of the objectives as a sacrificial part. I'm sure that these filters are very cheap compared to having the factory replace the objective lenses if scratching or other damage ever occurs.
I've done some basic google-snooping and it seems that there are 3 types of lenses that may work for me: haze or UV filters (I believe these are the same?), polarized filters, and clear glass. There are of course price differences between each. Other types of filters seem to absorb too much light. I believe that UV haze has a tendency to show on film, but that the human eye can't discern it so well. If that is the case, then perhaps the UV haze filter isn't the best choice? The clear glass would give the best light transmission but may be difficult to find. The polarizer may be good since I'll be using these mainly on a boat. However, my initial assumption is that the polarizer may be good for looking at nearby objects, but that they may not help when looking at items a mile or two in the distance. Is there a clear winner here for lens type? Any advice for any of the lens types or any practical experience with them?

Polarized are good over water, but they are normally darker and you will lose some light. Use an A2 if you can find them to fit the threads of the binoculars. The amber will remove some of the blue and increase contrast.

Need to follow the rules. Just hard to determine which set of rules to follow Now the rules have changed again. |
