X-T3 and a canon 300mm f2.8

Recommended Posts

Hi All,

  Im new to the fuji world of cameras and have ordered my first Fuji camera, the X-T3.  In a previous life I was a press photographer and had all the lens that would came with it like the long sport lenes.  I want to hear if anyone has had experience using canon glass on the fuji camera, especially the 300mm f2.8.

 

  Does it work? what is the crop factor and what adaptor to use is the best?

 

Everything else I will use in terms of glass will be fuji glass. just l ike photographing the kids playing sports a few times a year to justify not selling the lens.

 

many thanks

 

Chris

Yes, it works. There is no change in the crop factor — it is still the.1.5 ratio of full frame to aps-c. That part is tougher to answer, it depends on whether you want to use the lens in fully manual mode, or you want to use things like af, having the lens’ exif data reported in the file, etc. There are are adapters that are essentially manual connectors that do no more than let you connect the lenses to the body with nothing else enabled and there are adapters than give you full electronic control — as long as the lens had it to begin with. There is a company called Fringer that you can look into, there are others you can find by using your favorite search engine to search for Canon ef to Fujifilm fx adapters (or any variations on that).

Thanks Jerryy for the info.  I most definitely want to use the autofocus of the lens. 

Does the auto focus speed slow alot on the Fuji compared to been on a canon Eos system?

No, it is "just as fast". I use a Canon 50mm f1.4 and a Canon mount long lens with an adapter and you would need decent electronic measuring equipment in a lab setting to detect any significant af speed difference between using the lenses on a Canon body instead of a Fujifilm body. If you look on other sites as that have Fujifilm forums, there are shooters that post images of birds in flight, landing and taking-off, dogs in motion, race cars, etc. all down with long lenses through an adapter.

Or, to put it another way, no noticeable delay. That said, it also depends on the body and the lens. Fujifilm's fastest body will not make a slow af lens auto focus any faster.

Thanks Jerryy, I have ordered my camera and adaptor and looking forward to trying it out myself

Let us know how you get on - I'm using a Canon 200/f2.8 with a Fringer adapter and it works well although there are times when some sort of image stability would be useful.

Hi mate,. I have the camera now and using the fringer pro and finding the focusing jumps all over the place.

It doesn't 'lock' on to anything.  When it's sharp it's great but it sounds some time trying to work it out.

 

I'm using the canon 16-35mm f2.8 and the 70-200mm with similar results.

The 300mm lens test was a bust but that was my fault as I was still in single focus mode and not continuous focus mode.  I won't make that mistake again.

 

What setting should I have the camera on?  So far I'm really disappointed with the focus of the camera.  I hope it's user error and a simple fix.

 

Any ideas would be much appreciated

Does the focus bounce around when you are looking through the viewfinder?

If so, it probably means that the menu setting for touchscreen focusing is turned on. Turn it to off in the menu settings and the focus point should only move when you use the joystick to move it around.

Turn that setting to on when you want to use the back lcd screen as the “viewfinder” and then touch the spot you want to use as focus point. This is the cellphone method for focusing.

    • Hello, I just upgraded from a X-T2 to a brandneue X-T4 and compared to my old camera the lens release button feels just a little bit stiff/not so easy to press when a lens is mounted. without a Lens mounted the button can be pressed seemlessly. May I ask if that‘s normal?   thank you!  Marco
    • My X-T3 works fine with that version - your image shows X-T30
    • But... You can't monitor audio and power the camera from the same usb port. I've tried several splitter options and none of them work; leaving me to monitor audio with their usb dongle and pull that if I have to power the camera with my monitor battery usb out. When shooting video a camera is fully caged, with matte box, rails and follow focus. You don't want to change a battery out. You pretty much have to tear down your rig to do that...  
    • 23 f2 quite better of 23 1.4 is laughly.
    • Hi all, I just bought X-T3 camera (switched from Olympus) and have an issue with the rear dial button. I am not able to rotate it without pushing it as a button. That means it is too sensitive and I can rotate it just by nail and not by the finger. In principle I do not need it but it is the only way how to change values in Q-menu. Has anybody similar experience? If yes, any tip how to solve it? Thanks
