Err, this is Dante’s forum. Of course an Achromatic can be ‘justified’ :thumbs:A Phase One Achromatic just couldn't be justified :loco::grin:

Sweet! Please share feedback once you’ve gotten it back and done some testingMy Fuji GFX is at Kolari Vision right now getting converted to full spectrum, allowing me to shoot in IR simply by attaching the desired filter. I still need the ability to shoot in color, so the hot mirror filter with full spectrum conversion fills the bill. I'm opting for 590, 720, and 850nm. Unfortunately the AR coating is not an option on the GFX, but hopefully it is not an issue. I plan on using the 32-64 as my primary lens. Filters will be on the Xume magnetic filter system. Fingers-crossed---I'll get the camera back in a week or two.

Hi there, these are my images. I had Kolarivision convert a GFX for me back in May of 2018 and I'm very pleased with it. I can tell you that the native 45, 120 and 250 all work very well in IR, but there are also many wonderful lenses that can be adapted to the camera. The 23, 63 and 32-64 are not good performers in IR, as all have undesirable hotspots. I'd be happy to answer any questions you have...this is the album i was looking at..very nice images

Kolarivision does excellent work and Ilija is a great guy. They have converted 5 cameras for me, including the GFX. Unfortunately, the 32-64 does not work well in IR (see my post above), but there are numerous other lenses that you can adapt to the GFX for IR work. I'd be happy to answer any questions you come up with.I find it promising that in the series of images shared by Satrycon, the photographer used a variety of lenses without apparent issues with hot spots. I'd rather use one dedicated lens---the Fuji 32-64, but if need be, it looks like the Fuji 45mm is also a contender. Kolari Vision told me that they had only converted one GFX before. My Sony was converted by Kolari and I was MUCH happier with the work Kolari did for me versus the two I had done with Life Pixel. The Sony A7r conversion is fantastic, but I really am looking forward to the Fuji GFX and the 4:3 format. No more 35mm 3:2 cameras in my stable. :thumbup:

Thank you! Then you are the *first* to convert that Kolari mentioned to me!Kolarivision does excellent work and Ilija is a great guy. They have converted 5 cameras for me, including the GFX.

The 45 is an easy call, as it's an excellent performer in both IR and visible light. It's also (relatively) small and light. I have not tested the 110. I can tell you that the 120 is flawless in IR and the stabilization makes IR hand-held shots possible with my camera...same with the 250. I do think the 250 has 1-2 extra stops of stabilization over the 120 though.Thank you! Then you are the *first* to convert that Kolari mentioned to me!
I'm bummed to hear about the 32-64mm (and 23mm) having hot spots as this really is a wonderful general purpose lens on the GFX. I will have to re-think my approach, purchase the 45mm and re-purchase the 120mm (yes, selling an item and then re-purchasing the same item later is a virtue in Dante's realm :loco.
Do you know about how the Fuji 110mm performs in IR?
Ken
In my experience, hot spot problems are almost always a function of the lens and how it performs in the IR spectrum, and these issues are more problematic at the longer wavelengths (i.e. hotspots are worse at 850 than at 720, etc). I suspect that you will not see any hot spot issues with the 32-64 using the hot mirror filter, and would only start to see problems when you use the IR filters. I recall that the longer end of the zoom performed better in IR, so it may turn out that you see little or no problems using the 590 and 720 filters and only the 850 filter is problematic, and then only at the wide end of the zoom. If you already own the zoom, you should definitely do some testing with the converted camera before you buy the 45, as the 32-64 may be usable in IR with only a slight compromise at the wide end.My Fuji GFX is getting converted to Full Spectrum, allowing me to shoot in color using a hot mirror filter, and in IR by using IR filters in various wavelengths, 590, 720, 850, etc.
I wonder if the issue of problematic hot spots is of the same degree for a FS conversion or a IR conversion, e.g., 850nm. ?
If the Fuji GF 32-64 is problematic with hot spots when shooting IR, is it still usable when shooting in "color" using the hot mirror filter---or would the hot spots persist? :loco:
My thoughts are the Fuji 45mm looks to be a good lens add----and it might soften the blow if I could at least continue to use the 32-64 just for shooting in color....
I can hold off on longer focals such as the 120mm, though I think I might prefer the 110mm, if I knew it would be free of hot spot issues....
I appreciate your input Josh!

If you can hold off until April then I'll have all the lenses (except the 110) for you to try while we're in Tahoe. 23, 45, 32-64 (which you already have) 120, 250 and the 100-200 should be with me by then...My Fuji GFX is getting converted to Full Spectrum, allowing me to shoot in color using a hot mirror filter, and in IR by using IR filters in various wavelengths, 590, 720, 850, etc.I wonder if the issue of problematic hot spots is of the same degree for a FS conversion or a IR conversion, e.g., 850nm. ?

I already have the GF23 and will be selling it. I really don't want to expand my GFX system as the Phase/Cambo are my system of choice, with the FS/IR conversion just to add some variety and spiceIf you can hold off until April then I'll have all the lenses (except the 110) for you to try while we're in Tahoe. 23, 45, 32-64 (which you already have) 120, 250 and the 100-200 should be with me by then...
