I am only testing very, very lightly - the Canon EF 50/1.2 L lens with the Andoer EF-GFX AF converter - which allows me now to adapt any Canon EF lens to the Fuji GFX 50s II medium format camera.

But I don't really have the time to do anything special - because in one hour, I have to go to work, doing my night shift at the subway.


Using manual focus

However, I wanted to test the funky Canon EF 50/1.2 L lens, simply to see how it performs (in the close range) And yes, it does have corner shading - which isn't a surprise. But since I am using it in the closer range, it doesn't really not matter. Given it's suboptimal performance in the close range, the 50L lens combined with a Marumi achromat closeup lens, allowing me to get closer than the normal minimum focus distance of 0.5 meter.


Speaking of AF performance

Well, it is is slow (since the Fujifilm GFX 50s II and the other 50 models) only has contrast based AF - everything is more hesitant in terms of AF performance. Do not compare this with normal fullframe cameras - they are light years ahead.

But these things do not truly matter to me personally - because i use the Fujifilm GFX camera more of a manual Medium Format Camera - which means, I set the focus manually. Yet this Andoer adapter allows me to control the electronic aperture from the camera body. Also nice is the transfer of EXIF data, which means the images contain proper info of lens type and which aperture was used.


What about portraits ?

Most likely, if I ever would use this lens with people, especially at lower light levels - i would only use with manual focus. Albeit I rather use my Canon EOS R6 in such situations - because it is more reliable, intuitive and not a big deal to use a lens manually.

The Canon EF 50/1.2 L also can be used with AF on the EOS R cameras, being far more accurate in setting correct focus - compared to DSLR cameras such as EOS 6D, EOS 1D Mark IV and similar - which more often than not, misfocus with this 50L lens.

As i said, it is a tricky lens - but becomes a good AF performer on EOS R type of cameras.


Turns into a 40mm f 1.2 lens

Because the Fuji has a larger sensor, the effective / overall focal length looks more like a 40mm f 1.2 lens. You get the same, extreme shallow DOF (Depth of sharpness), and excessive, dreamy background blur. The main photo above, was taken at ƒ 2 - which means stopped down a bit, but i also used an achromat close up lens (Marumi +3). Those close up lenses are of high quality ensuring good sharpness, despite now going closer to your subject.

You can make an object look very different due to the extreme thin sharpness, the strong background blur, by going that close to your subject/object.


Lens hoods can become too narrow

Also remember, that when you use fullframe lenses on a camera with larger sensor, their focal lengths turn out wider; which means, that the original lens hood can now introduce dark corners (as well) - because it is too long (too narrow) for a wider angle.

Worth to remember.


Upcoming weekend

I hope I have the mood and feeling to do some nice photography during my prolonged weekend. This far, I gotten stuck in brief testings between various lenses, cameras and adapters. Which is more geeky, technical and so not creative... i mean not really. It also dilutes the core creative energy, i have noticed.

You know; when STUFF takes over ideas, mood and spirit, so to say.
