Yep, pretty good, Peter.
Thank you, Gentlemen.
A few from me. I may have posted these before. Thought they would go well here.

Those are wonderful, Jon!
Thanks Peter!
Wow, that one really rocks, Peter.
:) The whole trip was kinda rocky. Thanks, Tuco!
Testing D850 (not IR converted) with Komei IR filters 680, and 720. The 720 (and 680, for that matter) considerably darker than my other 720 filter, making it challenging to focus. But if I cupped my hand around my eye, I could see the image enough to focus... there was considerable focus shift.
The image on the left was taken with the 680. The one on the right was with the 720. I shot with ISO 100. Exposures at f/8. 5sec for the 680, and 8 seconds for the 720. No hot spot. Lens was the 20mm 1.8G. I will also test the 720 and 850 with Rollie IR film.
Good stuff, Andrew. Thanks for sharing!

Excellent, John! What conversion did you have done?

Dude, very nicely done.
Really happy to see that my Nikkor 24-70 2.8G lens works really well with my 720 filter (Zomei). I tested it at 24mm and at 70mm. No hot spot.
That's good news, Andrew!
By the way Peter, I like your 'rock' series. Where are these anyway?
Good ones, Jon! Most of my recent pictures are from Garden of the Gods, which is just outside of Colorado Springs.
I have photographed some of these very rocks with my 4x5 Norma back in the late 80's.
Daniel, do you have any scans? I'd love to see some of them.

From 30 day photo trip to Colorado Autumn 1992. 4x5 and some 8x10 Sinar Norma, original Sinar Norma lenses, HP5 (not +) processed one side of holder in D76 1:1, other side PMK Pyro+. I have 90+ negatives from this trip and some I have not printed. I lived in Colorado for a while and it was like returning home
Those are really nice, Daniel. I wish I could've taken my LF kit along, but it wasn't in the cards.
A few today from Magnolia Gardens. Processed them a bit differently.

I really need to take a trip this summer. Just somewhere different!
Those are wild (and fun), Jon!
Cheapest way to do digital IR, if you already have a dumbphone.

iPhone while holding the IR72 filter in front of the lens.
De-saturated, then adjusted levels in PS.
Wow, Ari. That's much better than I expected!
I just stepped outside and took a picture with my OnePlus 7t through the R72:

There ya go, Peter. Nice going.
I'm sure mine could look better if I did some fancy channel mixing stuff, but it's ok as a snapshot.
The hardest part was not getting my fingers in the view. My filter is a small 46mm.
There are filter holders for phones available online.

Nicely done, Tuco.
I ordered a filter stepper ring for this lens and trying it out with the IR filter.

Thanks.
My D810 conversion is going to be on hold. I sold off some of my primes for that system and have relied on some bulky zooms to fill the focal length gaps. But after trying the zooms out with the R72 filter, they didn't do so well with having a hot spot compared to the lenses I've been using on the M9.
Tuco, I'm sorry to hear about the problems with your zooms.
Tuco, it's tough knowing which are the hotspot-prone lenses. Zooms can be more affected than primes.
Every IR conversion company has a list, published on their website, of good and not-so-good lenses for IR.
A lot of them are excellent lenses for regular digital photography, but don't work so well with IR.
One problem with the lists is that some caveats come with them, results can be subjective: tested incorrectly, under improper conditions or settings, or the lens could be suffering from some unknown issue.
And from what I've read, you're also more likely to get hotspots if you use a filter on your lens vs. converting your camera.
I've tested a few Nikkor lenses with my Nikon D700.
AF-S Nikkor 14-24mm f/2.8G ED works great across the whole range of mm's and from wide open to f22. Past f11, it becomes diffraction limited though.
AF-S Nikkor 24-70mm f/2.8E ED VR works great across the whole range of mm's, but starts to get a hot-spot at about f8.
AF-S Nikkor 70-200mm f/4G ED VR - not tested yet.
AF-S Nikkor 200-500mm f/5.6E ED VR - not test yet.
I have a few older Sigma lenses I have not tested either.
BTW, Peter, that broken house is a good find.

A friend's wife suffered a stroke five weeks ago and returned home this past weekend. Having some experience as a caretaker, I offered to spend the weekend helping out as she made the transition home and they both adjusted to their new normal situation.
This resulted in me spending some time in an older part of the Phoenix metropolitan area where I hadn't previously photographed, so when I was able to get outside for a few minutes in the early morning, I wandered around a bit with my IR camera and took a handful of handheld photos, including this one around 6:15 am today:
