Opteka OPTIR55 Report
Opteka OPTIR55 Review by David K. Keith (Clifton Springs, N Y)
SSSOOOOO much easier than the old school way. Easy as point and shoot.Gotta have a good printer though. Going to try table top color next. All work done with a Sony A-380.
Opteka OPTIR55 Review by B. Wilson
Filter fits and works well, though not like a true IR camera, but it does give some neat effects.
Opteka OPTIR55 Review by Ellie "Eilean Siar" (North Shore of Boston, USA)
This filter for 55mm thread on the front of your lens keeps out all wavelengths except infra-red. As you look through it, you will see practically nothing, unless you are looking at a heat source.
In use on my Panasonic digital camera model DMC-LZ50 which is full featured with many manual modes as well, it rendered the blue sky dark and foliage light. In Picassa, the Google photo editor, I changed it B/W or sepia to get the desired effect, like using infra-red film in my 35mm cameras years ago (along with a filter like this).
One should note that for close up photos it will be necessary to experiment with the focus manually. The reason is that IR light focuses at a different point than white light. Ask your physics teacher why. I don't recall if you focus to a point before the subject or behind - I have more experimenting to do myself. But this filter is a starting point for some interesting work: your imagination is the limit.
You might try WikiPedia on 'infrared photography' to see what you might find.

Opteka OPTIR55:: Description
Opteka specializes in manufacturing special optical devices for the past several years, would like to take this opportunity to introduce a newly developed product called the "HD² Infrared X-Ray Effect See-Through Multi-Coated Filter". This filter makes it possible for you to see images that are normally invisible to the human eye. It sounds like science-fiction but it isn't; this fantastic new product has been developed using the most highly advanced optical technologies available. This filter will filter out 99% of light seen by the naked eye only allowing infrared light through so that technically the naked eye can see 100% black when the filter is in place. Multi-coating prevents light reflection, ghost light...etc, making images clearer and sharper. On your digital camcorder, turn the "Nightshot" function on - the naked eye cannot pick up the high contrast black, so with the infrared filter and Nightshot combination, for example, it will help you see in the images provided, that we 'accidentally' spilt some permanent ink on this document and the text is now impossible to read. However, when we attached the filter to our Sony 'TR250PK' camcorder, the writing is clearly legible through the ink - thus the x-ray effect! You will be amazed with the power if you take the time to experiment and experience its capabilities for yourself. If you already have a digital camcorder with the Nightshot feature and are interested in experimenting with the X-Ray effect, this is by far the least expensive method, giving you the results you are looking for. Just screw on the filter, switch on the 'Night' feature, and you are ready to go!
