Canon EF 135mm f2L USM (with Hoya R72 IR filter)

Hi everyone,

I don't know if I've ever actually posted here. But I initially got my start with a couple conversions I did with Kolari/LifePixel as well as two other users from here.

I unfortunately had to sell all of those cameras to cover some medical expenses for my wife and have been struggling to get back into it without paying an arm and leg to convert a body, buying filters and finding a camera I like, to convert.

So anyway, in comes the camp snap. Currently on sale for $60, it's IR Cut filter is over the front element of the lens, and to get access to full spectrum all you have to do is remove that filter. Sounds simple enough right? Well, here are some pros and cons currently.

Pros:

Cheap - You can find coupons to make it even less. I paid for $66 for my last order with various coupons shipped.

Easy to obtain.

Low Risk/High Reward

It's a really fun beater for black and white using 720~820+

Fun, worry free shooting.

Cons:

The DIY factor - if you don't have the tools, or the patience to do this yourself, you're gonna have a bad time.

Zero control over aperture, shutter speed, etc. it's spray and pray.

No raw output

Only reversible if you invest time and effort into fixing it.

I've documented my journey with messing with the camera here:

Hello everyone,

I've been testing a LWIR UAV thermal setup with a wide-FOV lens in outdoor inspection scenarios and wanted to share a few quick observations.

Key observations

• Wide-FOV improves coverage, but reduces recognition confidence faster at distance
• Detection is still possible beyond expected range, but identification becomes unreliable sooner
• Atmospheric conditions (humidity / haze) affect contrast more than resolution in some cases
• Motion + small targets make interpretation harder than static specs suggest
• Lens choice strongly impacts how operators perceive thermal detail, not just FOV

Questions

• How do you balance wide coverage vs reliable identification in UAV thermal setups?
• Do you rely more on optics selection or post-processing for clarity?
• At what point do you switch from detection-focused to recognition-focused configurations?

If anyone has field experience with similar setups, would be great to compare notes.

I recently started experimenting with digital IR photography, but as someone who shoots film about 75% of the time, I wanted to try B&W IR film as well. I couldn’t find any info on using the Makina 67 for IR, but decided to test it. The camera did great, but I learned that b&w IR is more challenging than regular b&w which I personally find difficult already.

Everything except the last shot was on a tripod. I tried to hand hold the last one but I wasn't stable enough. Not as noticeable scaled down for the web, but it's a bit blurry.

Gear used :
- Nikon D70s (Full Spectrum converted)
- Old full frame kit lens 28-80mm
- Cokin cyan gel

WB on tree, R / B swap, G split R 50 / G 50.

I shot IR in 720nm for years but last year I purchased an 850nm filter strictly for monochrome IR
