I love using the Pentax 67 SMC 135 mm f 4 Macro lens (in this case - with the rotating Vertex adapter method).

Albeit it is natively not really a "Macro" lens - but optimized optically to work better for close-ups. With a native minimum focus distance of 75 cm - this lens only gives 1:3 close-up. I do like the better optical quality with this lens when going close - compared to when going close with other Pentax 6x7 lenses who are not optimized for near field photography.

There is clearly a difference to be seen - especially when using the lenses wide open !

The 135mm f 4 looks sharp (the little that is sharp, i mean, given the minimal depth of sharpness...) When you combine that lens with the Pentax 67 extension tubes - the sky is your limit.

And it works well. It really has a special look in terms of that you get close - but not too close - and yet have a wonderful blurry background. Yes, the above image of the spiral was taken at wide open aperture ƒ4


Minimal depth of sharpness

So, the depth of sharpness together with 2 extension tubes, taken at aperture ƒ4 - was perhaps just one or a couple of millimeters deep. Really minimal.

And that is what creates this Medium format charm. As if i would have used positive Slidefilm (Kodak Ektachrome) in the size of 6x6 or 6x7... I think that is so cool !!

Even if it isn't special for anyone who never really got in touch with film medium format. I mean there are so many ways today, to emulate images in certain ways - that i doubt the Vertex method is anything for people to write home about. There are many ways to get so a similar look, without Pentax 6x7 lenses, without a rotating Vertex adapter, and without a digital Fujifilm medium format camera

What I do here, is nothing than the merging of traditional medium format photography with digital photography. And I do it literally, because the large Pentax 6x7 lenses, their true image circle, are truthfully utilized on the digital sensor with the Vertex method. It isn't just "stitched together" - but it represents the real, entire look of 6x7 lenses on a digital sensor, as if using a huge 65x65mm sensor !


Fringer Pro • EF-GFX adapter
Very first impression

Well, the Fujifilm GFX in-house image stabilization now WORKS with Canon EF lenses. When i adapted the Canon EF 40/2.8 STM lens - well, guess what ? The IBIS works. Which extends the free-hand use of Canon lenses, without using a tripod.

That alone is already a worth in itself.

I am very pleased. The adapter breathes solid, high quality. It also exhibits an aperture ring; meaning you can also dial in the aperture by using the ring on the Fringer Pro. I can already this far say, that the Finger Pro adapter is here to stay - I'll not sending it back :-)

Maybe I should work some overtime at the subway, to re-fill the budget holes I created lately

Canon EF 35/2 IS
now fully works

This lens didn't work at all with the Andoer adapter, being extremely erratic, both with AF and without AF in manual mode - basically useless.

With the Finger Pro adapter - everything works. including Fuji IBIS (but you have to choose, whether you wish the IS of the lens, or the IBIS of the Fuji) Both do not work together in tandem.

That being said, it means that now a lot more Canon EF lenses actually work for me. (I am not talking about if they are worth it, in terms of sharpness and dark corners). That I have to re-test more thoroughly over the upcoming months.

Sigma ART 70/2.8 Macro
also fully works

It too works flawless. From being almost unusable with the Andoer adapter, it is now all supported and fully working, both AF accuracy and IBIS support, and of course EXIF too.

Absolutely fantastic, i must say.

Of course this makes me very happy to be able to use now a real Macro lens natively on the Fuji GFX 50sII camera both hand held as well on tripod. (I mean here in single shot 51 MP mode, not the 150 MP Vertex method with Pentax 6x7 lenses)

Naturally, the useful range of Canon EF lenses on Fuji GFX increase for me now...

100% screen size • (remember this is at ƒ2.8 - so DOF is very shallow here)


Canon EF 50/1.2 L
works, but AF is iffy due to the nature of ƒ1.2

This one works of course too - but the AF isn't so reliable because of the shallow DOF with the ƒ 1.2 aperture and the lesser optical quality at that aperture when you use it at minimum focus distance (which is weaker than at infinity - due to the lack of floating elements)

This can confuse the smallest AF point of the Fuji GFX 50s II (and even more so when you enable a larger AF point in the Fuji). So, check and re-check your focus in you pictures just to be sure it is at the correct spot.

Use manual AF if the focus turns unreliable.

I find the lens to be OK - because I know that this EF 50/1.2 L lens has always been a tricky lens, but i like its special character (for certain motives).
