[TECH] ZEISS Flektogon 20mm F2.8 // FUJI X-T3

I am doing a review of the Carl Zeiss Flektogon 20mm F2.8.
Choosing a lens regarding its defaults rather than its qualities. Vignetting, distortions and other chromatic aberrations are welcome! (Really!)

Merci Ben. Passionné d'objectifs vintage à caractère, comme toi. Merci pour ce partage, je viens d'en acheter un après avoir vu ton test. Amitiés de Belgique.

[@Skopefilms]

Une de mes optiques préférées ! Un bel achat ;)

[@Aqueouseyes]

Thank you so much for this video!!! Came out so beautiful🌳🌳🌳🌳 Definitely gonna go with this Zeiss ultra wide

[@Skopefilms]

Thanks for comment! I used a speedbooster with the xt3 so I have that ultra wide field of view.

[@KalleTheodor]

I have an X-T3 too and was just planning to sell my Flektogon, but this video changed my mind. :-D. Thank you for sharing! Merci beaucoup! :-D

[@Skopefilms]

Thank you! I only have some vintage Zeiss lenses with a cheap speed booster to emulate a full frame sensor. To me, Fuji color science and old Zeiss lenses is perfectly match!

[@feinschnittvideografie8624]

Lovely footage at the end! Thank you very much for your review

[@Skopefilms]

Thank you for comment!!

[@colingentile]

Très très chouette vidéo !

[@Skopefilms]

[@Skopefilms]

Avec plaisir !

Thanks for speaking clearly its been 33 years but I can still understand some French

[@Skopefilms]

You're welcome ! It's a pleasure, thanks for your comment !

[@elitefamilyparkour]

Completely agree. This felt like having a really good french class and learning about this beautiful lens at the same time. 2 for 1 :D

[@srdjanbasaric517]

Bravo. Exelent presentation of exelent lens.

[@Skopefilms]

Thanks a lot!!

[@OliwiaBoliwia567]

Great video, thnx. So much information 👍🏻

[@Skopefilms]

Thanks a lot!

[@viktor3628]

hi My father has a zenit 11 with this carl zeiss lens. We used lot of times when we was children with my brother. 80's 90's. very nice memories are attached to this machine . How did you make video?

[@Skopefilms]

Thanks for comment! Those are very beautiful lenses. That's why I liked to modded it so I can use it with every camera with an EF mount or with a speedbooster.

[@ohjajohh]

Great review, this lens is on my wish-list

[@Skopefilms]

Thanks! Very good lens, hard to fine in mint condition

[@waitwat1142]

I have one in mint condition (in its original case) if you're interested.

[@bradl2636]

How is linear distortion across the frame? Would you consider for architecture/interiors/urban style?

[@digitaljb]

Hi! Which speed booster did you use?

[@Skopefilms]

Hi! It was the Pixco x0.7 ;)

[@digitaljb]

@@Skopefilms thank you!

[@allo_es_me_sam]

Hello can you put on the reply for me all the modifications you used for this lens. I'm a little bit lost and I want to buy the exact equipment you utilised.

[@Skopefilms]

Hi! I simply had the Flektogon attached to a Pixco reducer on my Fuji xt3. For the mod initially it was a focus ring from followfocusgear but after using it a lot I figured it wasn't a great solution, the ring slips a lot when it's hot. Finally, I attached a step up ring in front of the lens to have the same diameter on all my lenses

[@allo_es_me_sam]

@@Skopefilms Thank you so much I bought the lens Im excited to use it.

[@Skopefilms]

@@allo_es_me_sam Hope you like it ;)

[@allo_es_me_sam]

@@Skopefilms hello, I bought a pixco reducer but it was the wrong one. I thought it was the one from your video but I got it wrong. Can u send me a link or the exact one that you got please?

[@Skopefilms]

@@allo_es_me_sam hi! I had the 0.72x reducer Pixco m42 to FX. I found it on eBay so I don't have any link to send

[@miam1074]

is there a difference between the version that has red numbering and MC sign and the one which is all white??? thanks.

[@Skopefilms]

Hi! It seems that the difference is in the treatment of lenses. MC is Multi Coated, so the lens has less light reflections and a much better quality at the end.

[@elitefamilyparkour]

Could you tell me how long the focus throw on this lens is? And how much you paid for it? :)

[@Skopefilms]

Hi! It is about 270 degrees from 0.19mm to infinite. I bought mine for 280€ in a pretty good condition, I think it was a good price.

[@elitefamilyparkour]

@@Skopefilms I own this lens and love it! Only problem: Cant focus to infinity. Tried various adapters and cameras. So I guess its something about the lense? I also noticed I can go closer than 19cm for close focus. More around 15cm.

[@Skopefilms]

​@@elitefamilyparkour Hi! I have no problem with the close or infinite focus. Even with an adapter, my close focus is about 19-20cm. Do you use any adapter? What camera do you use? I am afraid that the problem comes from a lens or a group of lenses that is not in its place or poorly screwed.

[@elitefamilyparkour]

@@Skopefilms Thanks for replying. Im using the K&F Concept Pro adapter and the camera is the Sony FX6.

[@Skopefilms]

@@elitefamilyparkour Oh, if you may have a test with an other adapter to check if it’s due to it or not

[@Studio23creation]

Merci ! Y a t'il d'autres grand angles avec bokeh tournant? Il y a bien le Voigtlander 35mm F1.4 MC, mais en dessous de 35mm rien d'autre à part ce Zeiss?

[@Skopefilms]

Merci pour le commentaire ! Je pense à trois optiques mais je n'ai pas eu l'occasion de les tester, à voir si les bokeh sont vraiment tournant... Le MIR 20M, le Soligor 20mm et le Vivitar 20mm. Il y a aussi pas mal de 28mm, je pense que dans le lot on peut en trouver avec un bokeh tournant

[@erick9762]

Super cette vidéo! Quel est le matériel (marque/modèle) que tu visses sur l'objectif entre 0:09' et 0:14'? Et dans quel but utilises-tu ce matériel? Merci!

[@Skopefilms]

Merci beaucoup ! Alors, je visse d'abord un speed booster PIXCO, qui me permet d'adapter l'objectif de monture m42 sur mon boitier en monture FX. Cet adaptateur a également une lentille de réduction de x0.7, qui fait que l'optique retrouve toute sa couverture plein format sur mon capteur APSC. Ensuite j'emboite un focus ring trouvé chez followfocusgear.com qui me sert à gérer mon point avec un follow focus lorsque je mets mon boitier sur gimbal ou autre. Et enfin je visse une bague d'adaptation pour pouvoir visser un filtre ND d'un diamètre de 77mm. J'ai une bague d'adaptation sur toutes mes optiques ce qui me permet de mettre ce même filtre de 77mm sur chaque objectif.

[@erick9762]

@@Skopefilms Merci!!

[@Mathukey1]

You’ve demonstrated this lens beautifully! Does using a speed booster add to the swirly character of the lens? I’m struggling to see the swirly character as pronounced on other reviews, so I’m wondering if you just happen to have a particularly swirly lens or the speed booster is adding to the character…?

[@Skopefilms]

Thanks so much! Yes it adds to the swirly character! The crop removes about 10% of the widness so the speed booster helps to have the complete field of view and the complete swirly character. The reviews are often made with apsc cameras with a simple adapter (with no lens in it) With that Pixco speedbooster it corresponds to a full frame camera and therefore has a wider field of view. If you watch some reviews with full frame cameras, it has to have that swirly character.

[@LeComtedeSt-Germain]

Trop bien, tu te l'es procuré où et à combien stp ?

[@Skopefilms]

Merci !!! Je l'ai trouvé sur ebay autour de 250€
