Fotga 43mm Six-in-One Adjustable Infrared IR Pass X-Ray Lens Filter 530nm to 750nm (43mm)

Quite a few reviews of this filter claim it is only a "red" filter, but that is not true. The range of adjustment is pretty much as advertised and it is a real IR filter. As a result, it produces images typically with dark banding much like a cheap variable ND filter. I have tried several settings and orientations with the sun and have found that there are usually dark bands in the resulting images, as will be seen from the It seems that many of the negative reviewers are inadequately skilled at taking photographs with IT. The camera I use for the IR shots has been modified to cover the entire spectrum. Aside from the red color, there is generally a need for post-processing to correct white balance as well as to swap the blue and red channels to obtain As shown in the attached image, there is no white balance adjustment. The image is directly from the camera at a setting around 550nm. It appears that the blue and red channels have been switched in the second image. It is recommended that you invest in fixed bandpass filters if you are serious about IR photography. In general, higher priced filters will yield the best You can choose between both Newer and Zomei's low cost IR filters sets with different wavelengths if you are on a budget. This is a good purchase if you are looking for a toy or something to experiment with.

Although the concept of the filter is awesome, it does not appear to work very well when it comes to strictly adjusting the type of light passing through. It turns out that this is accomplished by using a polarizing filter and that is what is rotating with the filter. The amount of light passing through the infrared filter is greatly reduced since the infrared light passes by at a lower frequency. There is only a small issue here, which does not concern me in the least. Two major issues with this filter, though the first is its image quality, which is lackluster. Images taken using this filter were compared to those taken using the Hoya filter, and there was a very dramatic difference in quality. These ones were not nearly as good as the ones resulting from this filter. because this filter is greatly offset from the lens, you will get a lot of vignetting in corners when you use lenses with focal lengths around 30mm (on the 35mm film scale).

I have two lenses, one for a DSLR and one for my iPhone, which I have adapted to use In my testing, I used filters of different densities for both devices. I white balanced the images with an infrared profile to reveal the luminescence of the vegetation, which is a hallmark of infrared photography. When the white balance is selected at a wavelength below 750nm, the tonal range should be While white balancing these filters at various densities, we obtained muddy color images. There are no infrared filters here, but rather red variable density filters which don't do a very good job. As the density of these filters increases, they cause some severe negative effects, such as It is generous to give one star. It is recommended that, if you are interested in experimenting with infrared photography, that you purchase a filter in one cutoff range, particularly if your camera has not been converted or been stripped of its hot filter. The extra cost may be worth it, but you'll need to spend a few more dollars. You get what you pay for with any filter made of inferior glass or optics.

Infrared light is being filtered through this variable filter. The markings are at 590nm and 750nm with a variable transmittance between them. Although I did get decent infrared imagery, I did not obtain great photos, especially compared to higher-resolution images A series of filters at the end. Comparing my variable nm filter with my Kolari Vision 590nm and 720nm filters, I chose the variable nm filter.

When the variable filter was used outdoors, the shooting was soft shooting away from the sun, and soft with some flare shooting toward it. Basically, you need other filters in order to achieve maximum sharpness. The two lenses in the variable filter resulted in double images of the compact fluorescent bulbs when shooting them through the filter when using the variable filter on a compact fluorescent bulb Also, it could be the fact that the inside element of my watch rattles (it's a little loose), but it will still fit. It is important to note that the unedited colors of the IR images were slightly different than the standard filters but that is not as crucial since most users do some editing to them. Basically, it works, but the quality of the image is not quite as good as a standard filter. Tests can be done for a much lower cost if you do not need orwant to pay for higher-level testing There will be no issues with the end filters.

There is a red filter, but the images are of poor quality. Hoya R72 works well for IR photography on my unconverted camera (Sony A7R), but I bought this one otherwise because my original Hoya does not fit the lens I'm now using, and the control over IR with this filter sounded neat. I just got red-tinted, not white-fluted images, like the Hoya filter gives me. Also, when set at max (750NM) I get quite a bit of ghosting over the image as the other reviewers have noted. Maybe this filter will work on an IR converted camera. I won't know for sure, but I'll order another Hoya to fit my new lens and maybe figure out how to use this filter later on. It works, but not as well as you would like it to.

If you have no experience with IR photography, then this filter is a great choice for you. As a result you get a decent range of options to play with before you buy a dedicated single filter. It sometimes works perfectly, and sometimes it has a nasty banding issue (see photos).

The cutoff filters will be available for 530 to 750 nm, but I am unclear how this compares. A spectral plot of selected values of infrared would be very useful to me. As far as I can tell, the cost is very reasonable, and it does reduce the number of filters that have to be carried around. It appears to be two red / polarizing filters rotated against each other that lighten or darken the filter when rotated against each other.
