IR Hot Spot Database


How can you help  ?

Sadly we find a lot of outdated databases online and not a lot of results for more recent lenses.

If you have some results different than the ones here, please send me a photo with the lens, filter and shooting parameters (aperture, camera, etc). I will update this database to add your findings.

Thanks a lot for contributing!


Tested IR filters

 - 830nm (Deep B&W IR)
 - 720nm (Standard IR - Hoya R72)
 - 590nm (Super Color IR)


Test procedure

 - Blank paper sheet on a wall, lighted by an incandescent light
 - For each combination of lens + filter, took some shots from f/16 to the lens widest aperture
 - For zoom lenses, tested all extreme focal lengths (i.e. 70 and 200 on a 70-200mm)
 - Compared the hot spots to the lens sharpest apertures (found on LensTip.com)
 - Full Spectrum Nikon D750

Note: these are not real-life tests!


Results

 - Results are underestimated: If you see barely a hot spot for a combination of lens + filter at a specific aperture, chances are that in real-life the hot spot will be more visible
 - Overall, 830nm produces more hot spots than 720nm, which produces more hot spots than 590nm
 - You could have different results than me: the procedure is not 100% scientific, this is not real life tests and IR is a combination of camera, lenses and filters
 - You can look at the full detailed results here.

We can roughly determine per lens and filter combination which is the minimum usable aperture. Then, we can compare these suitable IR aperture with the lens sharpest apertures for center and corners.

I came up with the following rating:

 â­: barely usable: the lens sharpest apertures have some hot spots for 830nm, 720nm and 590nm
 â­â­: partly usable: the lens sharpest apertures have some hot spots only with some filters
 â­â­â­: completely usable: the lens sharpest apertures do not create hot spots with any filter
 â­â­â­â­: exceptional: no hot spot found from f/16 to the widest aperture
