Finally, the last Sunday, I found some time to take my X-T1 IR for a walk. Not so far - just to the wood next to my home. This time black & white, but as I set my camera to write both RAW and BW, probably I will post also the color versions soon. You can see some pictures here:

I used 35mm f/2 - well, probably XF 10-24 would be more comfortable, but first tests have shown definitely that this lens is really poor for IR and ruins all the pictures. So now I have been thinking very hard what wide lens to use for IR.

What problem do you get with the 35mm f/2 for infrared? Looking at the images, I can't see any hotspots, so just wondered...

35mm works fine - I just need a bit wider option. The 10-24 does not work - it shows huge hot spot in the center, very sharp and visible at 10mm and a bit softer at 24mm.

Hello all, similar situation (X-T10 IR converted to 720nm) difficulties finding best lenses-tried numerous ones with poor effects, consulted numerous specialists Inc.: Kolarvision & Jasonfriend websites. I can't really justify purchasing the Zeis 12mm or Fuji 14mm-though would love to.

I understand the Samyang/Rokinon 10mm is worthwhile considering-but am enquiring if anyone has used a 7artisans 12mm for IR photography? they look reasonable, get decent reviews & are well priced. many thanks for your advice

Regards andy p

Based on personal experience, good IR lenses are: 14/2.8; 16/1.4; 23 (both versions); 35/1.4; 35/2 (up to f/8); and 50-140/2.8.  Other wide angles (10-24/4, Samyang 8 fisheye and 12) have bad hot spots.  Sadly, if you want a wide angle lens for IR photography, the number of choices are limited.

Hello & thank you  for your advice-a good list to note

Agree, not straightforward-I had a Nikon D70 IR converted to 650nm back from the day & used it frequently (to reasonable results) with a cheap dx 18-55 lense. Alas, not the same luck with Fuji (I changed systems completely 3 years ago) though I do prefer their bodies/lenses-they simply have more 'substance' 

I don't know how many lenses/websites/enquiries I've made over the last 6 months. I've purchased several lenses/bodies of eBay-only to send them back sorrowfully; due to the notorious hotspots at higher f stops. I'll be sending an xc 15-45 back tomorrow-which I bought on a recommendation from a pro. photographer who blogs about IR  too

My 2 lenses (10-24 & 18-55)  are great on the X-T2, but on the X-T10 are absolutely disastrous. The challenge is a decent wide-angle (ultra) lense is £400 upwards (I'm thinking 14mm, 18-135mm or Zeiss Touit 12mm) which compared to the price of the body (£290) is quite an offset; hence my 7artisans enquiry

If I am unable to get positive feedback about the 7artisans, I think I'll sell the 18-55 & purchase an 18-135 which will kill 2 birds; or get flush & buy the Zeiss!  Thank you again for your advice (I'll check their prices on eBay) 

regards andy p 

PS-do you know if ND filters will work with an IR converted body?

Forget about 18-135 for infrared photography in color - look here: http://eng.roguski.eu/2019/04/22/sunny-afternoon-on-the-banks-of-the-vistula/

This lens can be used for B&W infrared only. The hotspot is huge and awful.

Hello & thank you. unfortunately, i cannot see any hotspots on your 2 colour images? regards andy p 

If you have closer look at the center of each image, you will see pink-ish tint on the foliage - it should be white and not pink.

      Cheeper back-up to my X-H2 (AF between X-H1, X-T3, and X-T4)

      By Tomek666 · Posted

      Hi Guy, I need a secondary Fuji X to back-up my X-H2 cheeply.   I sold my X-T2 to get the X-H2 beause I wanted to increase my AF hit rate. That being said, can you comment on the hit rates between X-H1, X-T3, and X-T4 in 2024? With all having the latest firmware, is there a big jump in AF performace between the three? Thanks, Tomek

      Latest firmware update

      oh wow, that is very odd.  Can you not simply put any version you want onto a formated SD card, and install it like every other priece of hardware on the planet?   @botty have you tried a different lens, or updating the firmware on your lens (if thats the only one you have one)?

      GFX 100s not connecting to Mac via USB-C

      By jerryy · Posted

      A while back Apple put a security update in its operating system that requires users to give permission for USB C or Thunderbolt connected devices to transfer data back and forth between the device and the computer. If the user did not give permission, the  device could only use the USB or Thunderbolt port for battery charging. Initially, this update was only for laptops, they may have brought it over to desktop computers later. As far as I know, if the user accidentally does not give access permission, there is no easy way to reset this for a single device, but there is sort of a work-around described in the release notes: https://developer.apple.com/documentation/macos-release-notes/macos-13-release-notes Does this help?

      Unless this has changed - its never been possible to revert back to a prior firmware version on Fujifilm cameras

      GFX 100s not connecting to Mac via USB-C

      By jmm123 · Posted

      Has anyone else noticed that since one of the recent firmware updates: the GFX 100s will not connect to a Mac of any age via USB cable. I am currently on FW 2.11 on my GFX 100s. Using USB-C the camera will connect to both iOS and Windows and we can see and download image files. But now when connecting it via cable to a Mac - the camera will not show up at all.   I have been reporting this to Fuji support but it has not gone anywhere for months. TIA. John
