Verbatim Hot-spot Reports

This is an archive of all the the hot-shot reports submitted by the users of DPanswers. If there is a record for the lens in the DPanswers lens finder database, the finding has also been copied to the database record for the lens.

  1. Tom [September 1st, 2005 at 18:32]
    I found canon's 24mm prime also has a hot spot with IR photography.
  2. Muril [October 3rd, 2005 at 03:10]
    I found Tokina 12-24mm f/4 Digital lens has a hot spot in IR photograpy with my IRmod D70 Nikon.
  3. Nicolas Castañeda [October 5th, 2005 at 23:02]
    I use a Sigma 24-70mm f/3.5-5.6 UC with no hot spot at all. Also my Nikon 70-210mm f/4-5.6D doesn't produce hot spots neither.
  4. Espen Mills [December 16th, 2005 at 14:01]
    I found the Sigma 10-20mm (with Canon 10D + Hoya R72) to have some sort of hotspot, a big, low contrast blur, in the center of the frame. Although not as visible as the hotspot the 50mm 1,4 produces. But I don't think it is very usable for IR-photography.
  5. Nicolas Castañeda [January 2nd, 2006 at 03:59]
    I've start using the Nikon 20mm 2.8D and I'm glad to inform you that it doesn't has any hot spot and does have an IR index. So far gives very sharp images (from f4 and above) in my D70 using a Hoya R72 filter.
  6. Wallace Shackleton [January 18th, 2006 at 22:50]
    Using the Canon 18-55mm EFS, which has a hot spot, very noticable at 25mm but does not seem to be that noticable at the 50mm end of the range.
  7. Emmanouil Skoufos [January 22nd, 2006 at 02:46]
    I found that the Nikon 18-70mm has no hot spot with a non-modified D70.
  8. wyattwd [February 1st, 2006 at 16:31]
    I used 18-55mm at 50 mm and a Hoya 72 IR filter. I did not see hot spots but grain was terrible.
  9. Nicolas Castañeda [February 22nd, 2006 at 21:29]
    again I'm glad to inform you that using a Nikon 35-70 2.8D with the Hoya R72 there's no hot spot niether and it does have IR index too.
  10. may [March 1st, 2006 at 16:33]
    i've used a canon ef-70-300is on a canon 350d (digital rebel) and i've not seen any hot spot.
  11. Stephen [March 21st, 2006 at 20:30]
    My 300D Digital Rebel is now IR modified with an R72 filter. Here is my list of good and bad lenses:
    - Strong hot spot: Tokina 12-24 f/4
    - Moderate hot spot (may show up in real world photos, but probably not too often): Sigma 18-50 f/2.8 Sigma 30mm f/1.4 Canon 18-55 f/3.5-5.6 EF-S
    - Weak hot spot (probably will not show up in real world photography): Canon 85mm f/1.8 Sigma 70-200 f/2.8
    - No hot spot under any conditions: Peleng 8mm fisheye Lensbaby Phoenix 100mm f/3.5 macro
    I tested using a sheet of typing paper, as recommended somewhere. I've only seen a real world hot spot with the Tokina, but even that lens will do okay sometimes.
  12. Kevin [August 11th, 2006 at 03:12]
    The Tamron AF 18-200 F/3.5-6.3 XR (IF) Di-II lens produces a hot spot in all ranges and all f-stops.
  13. Kevin [August 11th, 2006 at 03:25]
    I have use the Nikon AF-S 18-55mm f3.5 kit lens with a IR-modified Nikon D50 and it works perfectly with no hotspots.
  14. Ansel [August 12th, 2006 at 13:43]
    I have the Tamron SP AF Di 17-35mm f2.8-4 which produces a hot spot in all ranges with the Hoya RM90.
    My Nikon AF 35-135mm f3.5-4.5 with B+W 092 and 093 works fine without any hot spot.
  15. Clark [September 19th, 2006 at 04:00]
    The hot-spot problem in the NIR is not limited to recent lenses. Today I tested my digital SLR with an old Contax-Zeiss 50/1.4 from the late 1970s and saw the effect rather flagrantly (093 filter, 1Ds Mark II). This lens was sold long before there was any such thing as a digital camera. Too bad. It's a great little lens in the visible band. I guess that it won't work for film IR, either. Surely people have grappled with this issue for a long time - infrared film is as old as the hills; yet I hadn't heard of it until recently.
  16. Rick Decker [October 27th, 2006 at 06:13]
    I have shot the Sigma 10-20 and the 18-50, on the SD10, and have observed no hot spots. With the B+W 093, I generally am only 1 to 2 stops more than normal metering. Thanks for your great site and tips.
  17. Rick Decker [October 29th, 2006 at 23:45]
    Reference Sigma 18-50 f2.8 EX, I have now taken about 30 shots or so with this lens. I have noticed a hot spot a few times. Strongest was on concrete in the sun where it was very noticeable. Other shots have generally not shown it or very lightly. So it should be used with caution. It seems that the hot spot is more noticeable on verticals than on horizontals. I also noticed this same effect with the Canon kit lens (18-55).
  18. agata [February 23rd, 2007 at 06:01]
    tamron 17-50 f2.8 has a hot spot with canon 400d
  19. blyg [May 2nd, 2007 at 16:34]
    Canon 200/2.8L produces a hot spot after f10-f11
  20. Matti Metsikkoe [July 21st, 2007 at 22:51]
    Thanks for a great page! I have also ventured into the IR domain and find it fascinating and challenging. What struck me as odd was that the Nikon AF 50 mm f/1.8 D was on the list of lenses that produce a hot-spot. I don't yet know how the lens will perform on a IR converted D100, as I am still waiting for my hot-mirror replacements from the USA, but it performs quite well with a Hoya R72 filter. I haven't shot a plain white page with it, but I can see no spot what so ever in any of the IR pictures I have taken with it. Also, how should I shoot the page? Inside or outside and how should the light enter the lens? Also, will that have any impact on real life photography? I can provide some pics if you like, just send me a mail.
  21. Dr. Kiss Ákos Zoltán [November 4th, 2007 at 20:53]
    My Nikon 70-300VR is completely free of hotspots at any aperture and any focal lenght on the D80. My 18-70 gives a rather ugly hotspot on the D80, however it's almost free of hotspotting on a regular D50. How's that? :o
  22. Adrian Stretton [December 2nd, 2007 at 22:11]
    The TAMRON 24mm f2.5 makes a good cheap IR lens I have used it on my Nikon D1x,R72,140 ISO,1.3 secs @ f8 and no hot spots!.
  23. Dr. Kiss Ákos Zoltán [February 4th, 2008 at 10:55]
    It's strange, but the sigma 105 DG EX macro is listed as free of hotspotting, while I'm experiencing strong hotspotting even on my IR-only D50. Actually, it's my most hotspotting lens, the Sigma 10-20 being the second.
  24. Nick Kiest [April 6th, 2008 at 08:19]
    I have a 10D converted to clear internal filter for astrophotography, scientific imaging, and art photography. With a 850nm IR pass filter, I get good results with a Canon 28 f/2.8, Canon 50 f/1.8, and the Canon 24-105 f/4L. I get poor results with my 70-200 f/2.8L. I noticed you had no notice of the 28 2.8 and 24-105L. I should be able to test some other lenses for you soon.
  25. Stefan N [May 27th, 2008 at 00:58]
    I have posted a few images taken with a Canon EOS 30D, Heliopan 715 filter, with either 10-22 EFS or 24-105mm L Canon lenses. No hot spots to report at f8.
    See link for images:
  26. Stefan N [May 27th, 2008 at 20:26]
    Just reading a comment above, the Contax-Zeiss 50/1.7 does not produce hotspots on Kodak HIE film, as that is what I used for a while.
  27. Paul Verwer [June 27th, 2008 at 21:58]
    The Panasonic/Leica D vario-elmarit 14-50mm/F2.8-3.5 asph. used on the Panasonic DMC-L1 produces a hot spot which appears to be more pronounced at smaller appertures (f/2.8: hardly visible; f/11: very obvious).
  28. initd [July 13th, 2008 at 18:32]
    My 300D is converted to IR-only by replacing the sensor's hot mirror with R-72 equiv. Use with 18-55mm lens kit and get no hotspot at all (up to f/11). My Panorama (from 12 pictures) confirms the data.
    BTW, the IR sensitivity is around +2 stop more from every ISO setting. Shooting in ISO 100 at noon is 1/250s, f/11.
  29. Kali [August 27th, 2008 at 21:42]
    Hi, I found your Digital Infrared Resource Page extremely helpful, thank you! I'm new to infrared photography (as in I've only shot about 25 IR images). I noticed a halo in the center of all my images and dismissed it as user error until I saw your webpage. The lens I used is the Tokina 28-200mm f/4.5-5.6 MF. It's not a widely used lens but I thought you might want to include it in your list. I wouldn't go so far as to say it's definitely not recommended because the halo is faint and widely dispersed but it is apparent as color variations once I begin post processing.
  30. Eric Bowles [September 18th, 2008 at 20:24]
    The Nikon 24-70 mm f/2.8 ED G AF-S does have intermittant hotspots for IR. I am using the lens on a Deep IR converted D200. 12 of 12 images had the hotspot. Bjorn Rorslett reported similar experience with intermittant hotspots.
  31. Tom Green [December 29th, 2008 at 06:27]
    Camera: Nikon D80. I recently rented the 28-70 and 17-55 pro Nikon lenses. both were totally free of hot spots. Better yet is the lens I just bought: the Nikon 16-85: a sensational lens, the sharpest lens I have ever shot, and totally free of hot spots.
  32. Walter [June 26th, 2009 at 22:33]
    Contax mount Carl Zeiss 85 mm 2.8 shows hot spot while Carl Zeiss 25 mm 2.8 and Canon 100 mm f2.0 do not. All lenses tested on Canon 1DS mk2
  33. ALwin [September 6th, 2009 at 12:04]
    I just wanted to give my feedback for the Tokina 11-16 AT-X DX Pro lens (nikon mount) when using it with a modified for IR Nikon D70s and D90.
    Using a R72 equivalent IR filter: At f2.8 the lens doesn't show a hotspot on the D70s and on the D90 it is almost invisible as the hotspot covers almost the entire sensor area.
    Increasing to f8, 11, 14, 22 the hotspot becomes more visible. Also the hotspot's visibility is variable in contrast to the angle of light reflection from the object being photographed.
  34. ALwin [September 6th, 2009 at 12:33]
    Just continuing from my last post about the Tokina 11-16 lens.
    Same lens same camera: Filter: edmund optics longpass filter (I bought the 2 x 2 inches size and cut the filter to the size I need to replace the internal cutoff filter, the IR filter cuts off around 650-680nm)
    On the D90, I should avoid using this filter for IR photography. Too much visible light seeps in, not enough cutoff. But I did notice that the hotspot with the Tokina lens occurs visibly only after I start using small apertures which goes in combination with longer shutter speeds above 1/10 sec.
    On the D70s, the Edmund optics filter works nicely though it still allows a little more visible light to seep in then the R72 filter, just a tiny bit though. Hotspot becomes visible with apertures above f8 otherwise it is nonexistent or not noticeable at all.
    Now I can't really say my tests are conclusive proof that the lens does produce hotspots at certain settings. The hotspot may be caused by the way my cameras have been modified.
    For the D70s and D90, I have removed the internal IR cutoff filters and replaced them with the Edmund optics filter. However when I was testing with the R72 equivalent filter, it was a 77mm screw on filter which I put on the lens (while the edmund filter was already inside the body). So basically I was combining the filters.
  35. Cannockwolf [September 6th, 2009 at 23:14]
    I have a converted Nikon D200 with a Lifepixel 830mn filter the lenses i have tried on it are as follows
    - Hotspots: Tamron 28-300mm (non VC), Siggy 10-20mm, Nikon 24-70mm
    - Good for IR: Nikon 18-35mm (excellent in fact), Nikon 14-24mm, Nikon 50mm f/1.4D.
    I need an UWA now my siggy is out of the question.
  36. Gert van Duinen [September 23rd, 2009 at 02:01]
    I can confirm that the Nikkor 28-80mm 1:3.3-5.6 G works flawless on an unconverted D300 with an IR-720 filter. No hot spots from any aperture at f/3.3 to f/22. In fact this lens should be on the list of best IR capable lenses, it's a tack-sharp $30 bargain of the year, at least if you can get it.
    Read more about my findings here:
  37. Tom Green [October 17th, 2009 at 03:23]
    my new Nikon 24-85 2.8 lens is totally free of hot spots; a nice surprise.
  38. Ashley Pomeroy [November 16th, 2009 at 13:22]
    Yesterday I had a go at infrared photography with my Kodak DCS 560 and an Olympus 24mm f/2.8. I do not recall the serial number, although I believe the lens was manufactured in 1982 (Olympus changed lens coatings over the years).
    It did not produce a hot spot at f/2.8 or f/4. I did not stop it down beyond f/4.
  39. John Statue [January 5th, 2010 at 19:07]
    I own a Canon 40D SRL camara and use a Canon 18-200 EF-S USM IS and fixed a Cokin infrared filter into the Cokin filterholder at the front.
    It was a tryout for infrared photo's. and it works. I do not see any blurs or spots or any other disrubsions.
    I have not succeeded yet into a perfect b&w but that was because I had not the right shot for it. It is very snowy now in the Netherlands.
    But I am sure that when the wether conditions are ok, like in the summer, I will make very good IR-pictures. (I'll hope that my Englisch is good enough)

    Hello, I got my new camera last week, a Canon 500D modified with a 700nm filter. The focus was calibrated for the wide/ultrawide range. I tried some lenses:
    - Sigma 15-30mm : ok
    - Sigma 70mm macro: bad, hotspot
    - Sigma 18-50 3.5-5.6 DC: ok
    - Sigma 12-24mm: very bad, no hotspot, but totally out of focus. At the far end above infinite, the focus is about 1m.
    I would appreciate if anyone can shed some light on this strange behaviour. The Sigma 12-24 works perfectly on a Canon 5DII.
  41. joa [April 13th, 2010 at 05:09]
    I am using the Nikon d90 kit lens, 18-105mm, it gives a hot-spot with my Hoya R72 filter.
  42. Christopher [July 1st, 2010 at 18:52]
    Here are some recommendations for good lenses from Canon.
    - EF 80-200 2.8 L Superb, superb! Even better than the newer descendants as you only need to refocus at 80mm (from 100mm up it is apochromatic). Big minus is its heavy weight and inability to use Canon teleconverters.
    - EF 100-300 5.6L Another fantastic lens, but quite a prima dona generally. It's actually better suited for digital IR than film because it does not like any filter that is not clear: you lose autofocus, then the image is so dark you cannot manually focus! I'd recommend this only for converted cameras so you can just use a UV or other protection filter. Again, at the widest setting (100mm) you have to refocus but from 135mm up you can use autofocus.
    - TS-E 24 Seems good, but I've rarely used it as it has nasty chromatic aberration on color digital. The few images I've taken have been good but they are very few and all in low light. I'll have to do some more shooting.
    Added info on two lenses already reviewed:
    - EF 50 1.4 Yes, sometimes has a hotspot. Worse is its notorious tendency to front focus even in normal shooting, so that even when you refocus to the IR mark the picture may stay sharp. A very frustrating lens to use in IR. However, I've noticed on a very few shots under tungsten lights I have gotten what looks like steam or vapor from people against dark backgrounds. A very cool effect and I don't know what it is (heat and sweat?). It is very rare and unpredictable but fantastic when it happens. It keeps me shooting this lens in IR. Kind of like buying a lottery ticket, I guess!
    - EF 16-35 2.8 L I bought this lens specifically so I could shot IR and was rewarded with its notorious and nasty hot spot. This on top of a generally propensity to flare. Not recommended, although sometimes you can get a good image, and some of the marginal images can be cleaned up in post processing. Instead, go for the absolutely glorious EF-S 10-22mm, which is my hands-down favorite Canon lens for shooting infrared. Maybe its the Super UD element but it is clearly superior even when looking at thumbnails.
    That's it. I hope my info was useful. Happy shooting!
