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.

    • I use a TECHART ring to mount Canon EF lenses on the GFX 50S-II and 100S-II, maintaining image stabilization and autofocus. The only limitation are lenses with a small rear element diameter that make it impossible to cover medium format. Fast lenses like the EF 85/1.2L or the 100-400L, however, work great.
    • I also use a Nikon to GFX Fringer and it works very well.  24mm f/1.8 vignettes so best used on 35mm mode.  50mm f/1.8 covers the entire frame very well with no issues and is a superb little lens. 105mm Sigma vignettes slightly but is perfectly usable. 300 f/4 likewise the 105.  I have a 70-200 f/20+.8 incoming to test so will report back but I'm expecting a little vignetting.  Even in 35mm mode the image is still 60MP and if you're prepared to manually crop and correct you can get 80-90 MP images.  I also have a C/Y to GFX adapter.  The 24mm Sigma Superwide vignettes strongly. Ditto 28-80 Zeiss Sonnar. 80-200 f/4 Sonnar is perfectly usable. All work fine as 35mm mode lenses.  I also have an M42 adapter which I tried with the Carl Zeiss Jena 135mm f/3.5 with good results. 
    • Thank you. I will research it.
    • Ahh, the infamous brick wall photos… 😀 According to internet lore, if the dng converter does not properly apply the corrections, you can have it apply custom profiles that should work for you. How to do that is waaaaaay outside of this comment’s scope, but there are plenty of sites listed in the search engines that step you through the processes. Best wishes.
    • Jerry Thank you very much. That is extremely helpful. It seems that the camera and the lens have the latest firmware update, so it appears that the corrections should be applied automatically. The lens arrived this afternoon and I took some quick test shots, in which the correct lens information appeared in the EXIF files, so that sounds good. I used Adobe DNG converter to convert the Raw (RAF) files, and then opened the DNG files and saved them in PSD format. However, with a beautiful, clear, cloudless blue sky, there were no lines near the edges to check if distortion had been corrected. Another day I plan to photograph a brick wall. Thank you for your help.
