Lens Test for IR Compatibility (For Hot Spots)
* Test done with Canon 350D-IR (ELP Filter)
** Test done with Nikon D70-IR (Hoya R72)
***Test done with Canon 40D-IR (700NM Filter)
(All Tests are done at various stops for both focal range and F stops.)
(Almost all the tests are done using my own lenses & converted bodies, so feel free to ask me anything.)
(Me no expert, but super curious and crazy enough to keep on buying lenses to try and try)

** Nikon Mount Lenses (Tested on D70-IR)/R72 Filter
1) Nikkor AF-S DX 18-55mm F3.5-5.6G VR
- Excellent match, not hotspotting at all.

- But gets sharper from 35mm and above.
(Not sure if this is the lens thingy or the focusing needs adjustment)
2) Nikkor AF-S DX VR 55-200mm F4.0-F5.6G IF-ED
- Another excellent IR Lens on the D70-IR.
- Clean IR Photos with NO Hotspot!!!
3) Sigma 8-16mm F4.5-5.6 DC HSM

(Purposely got this in Nikon Mount as a Brother here requested it to be tested).
- Got hotspot at 10mm, 12mm focal stops.
- I shot using F8 all the way for this lens due to time constraint at time of testing.
- No sure if this happened because this lens in front cannot put filter (if filter has got anything to do with the hotspots)
- Not My Lens.
