Fringer (Canon) EF-GFX adapter --- Post Full Resolution Here ---

moimoi said:

Hi guys,

I took the plunge and ordered the Fringer EF-GFX Pro adapter. I am supposed to receive the little beast sometime tomorrow. No chance I will be able to play with it until Thurday night, but I shall have more time on Friday and over the weekend. I am hoping I will be able to post some full resolution samples (taken from the GFX50R) toward the end of the week.

The EF lenses I am thinking to test are:

(i) Canon EF 35mm f/1.4L II USM

(ii) Canon EF 70-200mm f/2.8L IS III USM

(iii) Tamron SP 45mm F/1.8 Di VC USD --- I am particularly interested in the comparison with the GF 45 mm f/2.8 ;-)

(iv) Tamron SP 85mm F/1.8 Di VC USD

Additional Notes (edit): Has anyone tried with the Canon EF 500 mm f/4 lenses (I, II or III)?

These two Tamron lenses have nice and relatively smooth bokeh, so I am looking forward to seeing the results when mounted on the GFX cameras.

PLEASE feel free to post full resolution files in this thread from any Canon EF (or third party EF lenses) + GFX camera combo!

Thanks,

Max

Attention: please always indicate whether pictures are taken in full MF format or in 35mm mode (which is also used from time to time, as it improves compatibility).

Some Tamron SP 45mm 1.8 samples…

I had some issues with the AF and the IS with an early Fringer firmware on the 50S. But it became quite responsive with subsequent updates.

This lens works very well for people photography, somehow like a 35mm 1.4 on FF.

The samples were taken hand held some in low light, full crop.

As far as the vignetting goes, this is rather very good. I am on my phone so cannot check the Full resolution to check for sharpness but I will check later during the day.

Thanks for posting these samples.

Cheers,

Max

You are welcome!

Yes vignetting is really minimal and is corrected in camera by the Fringer software if it needs.

Those were taken on tripod, probably ES, MF, no IS and while holding my breath. ;-)

For comparison, the EF 85mm f1.2 has a smoother out of focus gradation as it is expected from a more luminous lens. This lens had no Fringer profile at the time I took these, but I believe the V2 has. I applied the profile for full frame.

I just checked the files at high resolution. They look surprisingly good in the center at f/1.8.

Very very usable for portraiture. How does it compare to the 80 f/1.7? Do we get 90% of the performance of the the GF lens with the Tamron 85 mm. If so, that's a steal and the Fringer adapter makes a lot of sense. Specially considering that the Tamron should have faster AF than the GF 80 1.7

Very nice, and it is super useful!

Dumb question (I don't think the Fringer adapter yet). How do you apply the correction? Via PS/LR/C1?

As soon as I get my copy, I will download the latest firmware, then will proceed with some tests!

Hi

Thanks for showing the great pictures.
My copy of a Fringer EF-GFX Pro should be arriving soon, then I can experiment myself.

BUT:
A question for real use (beside of academical questions):
I also have the EF 85mm f1.2 lens. the way I see it, that corresponds to a focal length of 107.6 on MF, so practically 110mm.
If this is correct, the next step would be to compare the image quality of the EF85mm1.2 with the GFX110mm.

If there is a big difference (i.e. the GFX110 is significantly better), then you can skip the comparison.

If the lenses perform similarly, then Fringer only makes sense if you don't yet have the GFX110 and already have the EV85mm1.2.

And what is of course most interesting (at least for those who have all, GFX110, EF85mm1.2 and the Fringer): is EF85mm1.2 possibly even better in certain areas?

Just an idea

Thanks, glad that this was useful !

All samples from the lilies are actually from the GFX full sensor, and none was cropped.

So it's the other way round: 110mm for GFX is grossly an 85mm equivalent on full frame. When you mount an 85mm, either a GF of a full frame lens that covers the GFX sensor, you have an equivalent 68mm on Full Frame. Again, this is not precise and the ratio is 3/4 for the GFX and 2/3 for full frame.
