We have talked a lot about the Canon EOS R100, but there are some good uses other than a doorstop, or an experimental submersible for the Canon EOS R100, so we’re going to dig deeper into this.

 
Anecdotally, the people I know who want full spectrum or Ha modified cameras go for R8 body only as they still want "decent" quality.
I can see why having just a infrared camera conversion could go for a R100 but wouldn't they start with a IR front filter and just use long exposures/tripod?

I had my M6 converted. The EF-M lenses are surprisingly good for IR, and decent for UV (especially the 22/2).

There are reported issues with some RF lenses and long exposure IR, the lens itself has a weak IR light that shines toward the body.

A R100 conversion adds up though with price being $950 including the body.
As @neuroanatomist mentions, there are issues with some RF lenses for long exposure IR "leakage"/ hotspot. Kolari only tested some RF lenses so others may also be problematic.

The cost is 300 for the conversion - I'm not sure where you are getting $950 from

There are, a fair amount of Canon RF's L's that are not suitable for IR, that's for certain.

that's one of the "joys" of infrared photography, navigating what lenses work.

a couple of the Sigma primes on the M's had this problem too.

it's too long of exposure really, with more modern sensors in their cut filters, older DSLR CMOS sensors had a more relaxed cutoff, but these days? you are losing too much light. Also I don't think that would work for some filters such as IR chrome.

Well it was you @Richard CR who told us it was bad !!

"there are some good uses other than a doorstop, or an experimental submersible"

I actually asked Gemini AI for some commentary on the R100, and the shade was real. I was going to add it to the end of the article, but thought better.

When the R100 Mark II or whatever comes out, I'll go to town on it.

Just reading their website. I did say "including body"

GenAI just gave you back the comments that you had published (echo chamber) :ROFLMAO:

Erm, you put the use case for a manual lens twice. To be quite frank, 24MP in APS is a truckload of resolving power, more than most classic lenses can ever hope to match. There are a couple out there, but forget about any zooms, and even the vast majority of wide angle primes will be massacred by a 100% pixel peep.

The 18-45mm is a sad POS. It made me pine for the bulky EF 18-55mm IS STM that came with the SL1, a lens that vastly outperforms its RF sibling, despite being 10+ years older. As soon as I got some primes for my R50 it was relegated to a drawer.

The idea of making it an infrared camera is nice; do you have any articles detailing the performance of the basic RF primes for it? It makes sense, I can see how the R100 with the 16mm, 28mm and 50mm could be an amazing infra/UV kit at an unbeatable price.

yes, but slightly different rationales though.

then don't do 100% pixel peep. for that market - it's probably not that important.

try using DLO on the images.

that will be an article in the new year once I get my converted R8 and associated RF lenses.
