p.1 #1 · p.1 #1 · Infra-red Compatible Lenses


I've recently had one of my 5D's converted to IR and I'm currently using my 17-40 f4L and 70-200f4L non-IS as well as the 300f4L but I would like a one lens solution for the IR camera of say 28-300 and was wondering if anyone has any firsthand experience of any lenses in that range that will work in the IR range without a hot-spot in the center.

Because of the focus shift I don't need to set the aperture larger than about f5.6 and because the effects of diffraction kick in about 2 stops earlier in IR I don't need to stop it down more than f16 so I figured one of the "Super Zooms" would fit the bill perfectly if I can find one without a hot-spot in the center.

The only one I've been able to find so far is on a list at lensplay.com, but I don't know how old the list is (maybe 2006?). Here's the link

http://www.lensplay.com/lenses/lens_infra_red_IR.html

to the page listing a Tamron 18-300mm XR lens as compatible but I'm not sure if that's the same lens as the one I've found at an online camera store labeled "Tamron 28-300mm f3.5-6.3 XR Di VC".

Any help finding a lens would be much appreciated.

does anyone know if the 'hot-spot' issue hits both modified and non-modified bodies, or is it just an issue when a non-modified body is used with a screw on filter?

in my very limited research, I only see mention of the issue when screw on filters are used.

Interesting list - I can confirm some of the lens-specific IR performances there, but disagree in regard of the Sigma 10-20 mm lens. It unfortunately often produced a hot spot even at wider open apertures. Sometimes I was able to limit the spot by changing the camera-sun angle, sometimes the spot appeared no matter what. I use a 77 mm Hoya IR filter on top of the lens on my older Rebel XT camera.

For now, I tested some of my lenses in IR photography just by trial and error. The 17-40, as well as the 24-70 and 70-200 f4 lenses were all fine without hot spots, even at f8-f11.

As far as I know, it is a lens-specific matter only.

17-40 was one of the most hot-spot prone lenses on my crop IR-converted body.

Thanks for the extra list, many more lenses reported there.

I can also confirm that the Canon EF 300mm f/4 L IS is also a good lens for IR with no hot-spot at all though I haven't tried it with the 1.4 II extender yet.

The Canon EF 70-200mm f/4 L non-IS can produce a hot-spot ranging from very bad with the 1.4 II extender stopped down to almost non-existent bare depending on the focal length and/or aperture and angle to the sun (I haven't worked out all the variables yet).

My 17-40mm f/4 L is a great performer in IR on my converted 5D without even a trace of a hot-spot.

I've also tried my 28mm f/1.8 and it seems to work just fine although I've only used it for a limited time as the larger aperture isn't really needed along with the associated focusing problems in IR.

In my experience hot spots often also depend on the situation like angle of camera/lens to the sun, reflections etc. Some lenses are better in this regard than others.

I enjoy IR photography so over the last couple of years I tested many of my lenses mounted on a converted 5D then later my 5D MKII that were both converted to IR (RG715). I then further tested most with a filter (B+W 093) and then a Heliopan RG1000 on the lens. These were tested at various apertures until a hot spot appeared. Here are the findings I had

I disagree with that list, too, with the part about the 18-55 IS being a poor performer, I use it all the time on my IR converted rebel and it produces nice sharp results.

Thanks for the extra data points burningheart, very much appreciated

I need to do some methodical testing on some of my other lenses , but right now I'm having way too much fun just playing around as the nice sunny days are going to be very hard to come by in the next few weeks as the rainy season starts up here on the west coast of Vancouver Island.

Right now the front runner for a "mostly" one lens solution seems to be the Canon EF 28-135mm, I think I could by with this doing about 80% of the shots I would normally do but with the haze minimizing effect of IR, telephoto landscapes become more "doable" during midday and so a 28-200 or 28-300 would be a nice solution.

I've injured the tendons in one of my shoulders (which takes months and months to heal) and carrying camera gear only aggravates the problem, hence my need for a "one lens solution" combined with a grip and a hand strap on the 5D. I might have to look into one of the belt systems for carrying my existing lenses if I can't find a good "super zoom" that's good for IR work.
