guest post by Steel

Dear folks,

I am happy to announce the success of development of Steelsring smart adapters for C645 and EF lenses to GFX camera body. It is in production now, and will be available for sales in September, it will be reasonably priced, to be announced later.

Demo videos on youtube here:

These two adapters feature:

  1. Automatic lenses identification, includes all C645 lens, and theoretically all EF lens (but only Canon and Sigma lens will be tested).
  2. Accurate lens params (Lens type, name, focal length, zooming info, aperture, etc ) passing to GFX and EXIF recording. So you can use the right info for exposure, and know pictures took by which lens and in what params.
  3. Fast/accurate AF, comparable to FUJI GF native lenses. AF faster than CDAF mode of Sony E cameras. AF is not possible for C645 120 f/4 MACRO and EF brand MF lenses.
  4. Aperture control through camera body, works with all C645 lenses ( Can switch to Lens Aperture Ring control too ) and EF lenses.
  5. Image stablization activation/deactivation for EF lenses with IS, controllable from GFX body.
  6. Plug and play. You just use it as usual, no extra equipment/setup are needed. Mount your lens on the adapter, put the adapter on the camera, turn the camera power on, then you are good to go.
  7. USB socket for self-firmware upgrade.

All above features were implemented and tested already. When sales begining, C645/GFX adapter will be tuned against all C645 lenses including Mutar 1.4x. Not all EF lenses will be tuned into the EF/GFX first firmware release, but it’s upgradable.

Currently tested EF lenses are quite limited,

EF 135 f/2L, EF 24-105 f/4 L I,EF 17-40 f/4 L, EF 35 f/1.4 L I, EF-S 18-55 II, Canon EF TS-E 17 f/4L, Canon EF TS-E 24 f/3.5 II, Canon EF 100 f/2.8 Macro IS II and Sigma 135 f/1.8 art, Sigma 35 f/1.4 ART, Sigma 50 f/1.4 ART .

Goodbye Fuji X-T2: Why I FINALLY had to let it go at LivingVertical Youtube

The Good, The Bad and The Freedom to Say it All

I love the Fuji system.

And yes, sometimes I just can’t contain my enthusiasm and excitement for the Fuji X and G systems, which brings me to write long emotional articles when a camera gets discontinued or lose myself in a frenzy of happiness for a rumor, when I could have said everything with 1 headline and saved a lot of my spare time.

That’s who I am… can’t change it… deal with it ;)

However, this is FujiRumors… and I know that this blog is a big source for all things Fuji for many of you guys.

That’s why my number 1 priority will always be to deliver honest, good, fair, fast and accurate service to you… even if it means that sometimes we have to talk “bad” about Fujifilm.

So here on FujiRumors we are are free to…

  • write about my main 2 complaints on the Fujifilm X-T1 – read here
  • launch polls investigating why people don’t buy Fujifilm (highlighting the weaknesses of the system) – read here
  • We love Kaizen, but recently called the Wireless Tethering feature a Joke – read here
  • When we think Fujifilm is losing the path (and its “soul”), we report (and comment) about it – read here
  • When reviewers give negative feedback about an important key feature of a new camera (such as the hybrid viewfinder on X100T), we will report about it – read here
  • FujiRumors is regulary the first place that reports about issues and bugs, such as the mushy buttons on the first batch of X-T1’s and more

I’ll just quickly add, that I can do this only because I have absolutely 0% contacts with (and zero favours/money/support from) Fujifilm, which gives me an immense freedom to write whatever I want.

You guys, the FR-readers, are my only boss… and all I want to do is to deliver you the best content and rumors possible.

The Roundup

The Fujifilm X-System is not for everybody. Depending on what your needs are, you may be more or less satisfied with it. Some people love the X-system so much, that they can live with minor issues (maybe waiting for a Kaizen Firmware to fix it), some others just have to return their Fuji camera, just like LivingVertical did with his X-T2 (video above) or alastairarthur did with his X-Pro2 (link below).

But there are also many very happy Fuji users out there, who keep up producing great work with their Fuji gear (such as Kevin Mullins’ recent wedding Photographs)… and I’m happy to share them in this roundup, too.

This Simple “Trick” Will Show You When Your Fujifilm Camera Has Been Made


Ok guys, if you ever wanted to know when your Fujifilm camera has been manufactured, here is a simple way to find it out :)

All you have to do is to check out the first two figures of your serial number.

So, as you can see above, my good old (and now discontinued) Fujifilm X-T1 serial number starts with “42“.

This means that my Fujifilm X-T1 has been made in 2014, in quarter 2.

To check if this is correct, I opened a random image of mine (SOOC or RAW) with the Graphic Converter EXIF tool. Here is what it shows me: 2014:06:18… or 18th of June, 2014. So indeed, quartal 2 of 2014.

So if your serial number starts with, let’s say, 71, it means your camera has been manufactured in 2017, quarter 1.

UPDATE: Thanks to the FR-community, we have solved the riddle. As from Fuji’s page in Russian here (google translated)

1st digit = Year:
1 = 2011, 2 = 2012, …

2st digit/letter = Quarter:
I quarter = 1, 5, A, S, E, J, N
II quarter = 2, 6, B, T, F, K, P
III quarter = 3, 7, C, U, G, L, Q
IV quarter = 4, 8, D, W, H, M, R

Examples of determining the year and quarter of production:

Serial number 1Txxxxxx – the first position of the number – the number “1” means 2011, the second position of the number – “T” – means the 2nd quarter, accordingly the product was produced from April to June 2011;

Serial number 03xxxxxx – the first position of the number – the number “0” means 2010, the second position of the number – “3” – means the 3rd quarter, accordingly the product was produced from July to September 2010.

The production date itself is taken as the last day of the production quarter. Ie, if the camera is produced in the third quarter, the warranty period will be counted from September 30.
