HOYA UV-IR filters.
These are specialized filters that cut BOTH UV rays below 390nm and IR rays above 700nm. This is important because the visible spectrum is between 400-700nm. Basically UV rays and IR rays both can diminish image clarity and sharpness. But by blocking them both before they get to the image sensor there is a noticeable increase in image quality.
This infrared filter (Hoya RM-72 ) did not give me IR images when used with a Panasonic FZ-150 camera. No one seems to have the correct answer as to why ?????
This dark-red filter is necessary to get the full infrared effect with black and white IR films from Europe, since Kodak has stopped production of HIE. The filter is practically opaque, so it is best used with rangefinder cameras; otherwise, you have to focus without the filter, then put it on just before exposure.
You can't go wrong here. I use this with my Nikon D40 and have got some beautiful shots. Some people feel that it's just a waste of money and doesn't give you true IR. Simply stated, they're wrong. You might want to do some reading about your camera's capabilities with IR (via filter) to see how well this will work. ie This works better on the D40 as opposed to the D60, pixels I've read being the factor there. It's highly affordable and unless you plan on working only in IR all the time it's a great bang for the buck. If you are going to primarily work in IR you're going to want to convert your camera, your exposures won't need to be anywhere near as long, and you'll be able to compose and snap your pictures as fast as you would on a normal camera. I've taken several hundred pictures with this lens since I first purchased it, primarily of nature landscapes, and I absolutely love it. Mine did come with a ghostly haze on it, but after some quick cleaning I was all set. If you're wondering if this will be fun and enjoyable and you know your camera is capable of producing good images with it, don't ponder any further just buy it. I use this on all of my lenses and get 0 hot spots.
Great filter, and great B&W photos. Adds so much to photography, back to where you can think and know more than the auto camera. Brings fun back to photography.
Definitly puts a different view on photos!
After viewing some spectacular images on the internet, I purchased the R72 filter simply to play in the infrared spectrum without the high cost of sensor stripping. I mount the filter on top of a rotating circular polarizer and generally shoot between 0.5 sec and 20 sec. tripod-stabilized exposures. Simple Photoshop workflows render stunning results. For an inexpensive introduction to IR photography, this is an amazing bargain.
Bought this filter to begin playing around with IR on a Pentax K10D DSLR. The quality is very good. I can't evaluate the filters technical component just yet as I am still working out the settings to get thing right. There is lots of good info on IR photography to help you get started. So far seems like a good starter filter. I would buy again and buy future Hoya filters based upon build and quality.
I really love the results I've gotten already with my first use of the filter. It was the right one for my Konica Minolta D7 and what I was looking to achieve.
I have been shooting photos on and off for a couple of years, but got back into it when I picked up the Nikon D40. To get things going, I saw some photos in infrared and wanted to get the same effect without forking out the cash just yet. The filter worked like a charm, but from what I have experienced is just a filter for the outside in the sun. Not for use in-doors or at night. I love the fact that I can shoot awesome pics, but when you constantly have to remove the filter to focus it can get tiring. But that is the only low point of this filter. Everything else is awesome. Word of advice, if you want the infrared look then use B&W setting. But if you use normal color you will get a pretty cool looking magenta/infrared effect.
This is an excellent filter for getting started in IR. It does not block out all light other than IR but most of it. It's perfect if you want to try false-color IR since it lets a small amount of the non-IR spectrum in. It's also inexpensive compared to the true IR filters.
