56mm 1.2 Autofocus Issues

Hi all, 

 

I've had the xpro-2 for about a month now and I like it a lot, but lately I've managed to put my finger on something that had been nagging me for a while. 

 

When shooting the 56mm 1.2 open (not necessarily wide open), autofocus is systematically off. And not a little off, massively so.

 

I was shooting a studio session last week, so I switched off to manual, and used the AFL button hoping that it would bring the focus closer. And lo and behold, it didn't bring it closer, it nailed it perfectly. 

 

So now I'm puzzled. I've heard of lenses that have backfocus, but why would the AF-L nail it and the shutter button mess it up ?

 

Does anyone have any idea ?

 

Obviously the solution is to decouple shutter and focus and only use the AF-L, but I've never used my cameras that way, and when doing street photo it doesn't strike me as the fastest way to get the shot. 

 

It only happens on that lens as well, the 35mm f/2 works just fine.

What does Fuji say? Always back-focus, never front?

I'm puzzled by your question about Fuji. Is there a way I can ask Fuji directly ?

 

I need to do more extensive testing, but yes, I think it's always back-focus (focus way behind the subject).

I have had issues with the Xpro2 and the 56mm as well.  Most of the time it hits...but there have been quite a few times where it misses quite a bit in good light, where I don't feel it ever missed on the XT1.

 

On a Facebook group there was another user with similar issues...I wonder if Fuji will need to update the firmware for the lens soon...hopefully...

      Infrared Photography on X-E2 665nm

      By Neil Rosenberg · Posted

      I'm not exaggerating when I say that I have searched with great vigor (and at great expense) for a way to capture IR images with a Fujifilm camera for which I didn't have to use major amounts of sharpening to bring out the best. Zooms, primes, Fuji, Tamron, Viltrox, Sigma, Zeiss ... probably 20 lenses all told. Plus multiple IR converted Fuji cameras, X-T1, X-T3, X-T5. I even tried different ways of filtering IR, such as using the Kolari clip-ins and lens-mounted front filters. I was ready to give up until I almost accidentally tried one of the cheapest lenses out there -- the little TTArtisan 27mm F2.8. No hotspots that I could see, and best of all ABSOLUTELY SUPERB SHARPNESS across the entire frame. It's this attribute that I search for, and until now, never achieved. In my prior attempts, I listened to the advice from the "pundits", picking up a copy of the venerable Fuji 14mm F2.8, the Zeiss Touitt 12mm F2.8, Fuji 23 and 35mm F2.0, even the very similar 7Artisans 27mm F2.8, and none of them come even close to the TTArtisan for edge sharpness in infrared. Incidentally, I'm using a Kolari 720nm clip-in filter. Sure the TT has its issues -- vignetting at 2.8, tendency to flare with sunlight nearby, but all in all, this lens is glued to my X-T5 for now. This image was taken hand-held with this lens -- completely unedited!

      In reply to the original question, it all depends on what you mean by infrared.  If you mean "see thermal information", then I agree with the comments here.  However, if you mean near-infrared, the X-T4, or basically any digital camera can be modified to "see" it.  Check out Lifepixel.com and Kolarivision.com for more info.

      XS10 and manual lenses

      No - I don’t think so - it means you can take pictures if you remove the lens completely - but I’m not sure that is a problem

      XS10 and manual lenses

      By mcewena · Posted

      I bought a manual lens over xmas and it took me a while to find the "shutter w/o lens" function in the menu settings.  So far I haven't found a way to either put that on the Q menu or marry that setting to one of the 4 custom modes.   Am I missing something? Is there a problem if I just leave that setting enabled even when the OEM auto lens is in place? tia

      Apple Support for Compressed RAF files

      By Greybeard · Posted

      It appears that Apple now (at last!) fully supports FujiFilm Lossless and Compressed RAF files. In the latest updates of MacOS Tahoe 26.2, iOS 26 and iPadOS 26 compressed files are supported in Finder/Files and the Photos app. Good news for those of us with Macs and iPads.
