Does not work with Olympus OMD EM10 Mark III

Does not work with Olympus OMD EM10 Mark III
It does not mount to Olympus OM-D E-M10 Mark III. The camera's body has a curve leading up to the flash and will prevent the mount from seating onto the camera body. The flash portion of the body will contact and rub the adapter and will not properly seat. Maybe for the PEN series but not the new OMD. If the mount were a few mm smaller in diameter it would work.

    I was definitely impressed! I tested it on GH5 using the following lenses: 16-35mm Mk III, 24-70mm Mk II, 35 Mk II 1.4, 50 1.8 and 24-105mm Mk I and they all worked surprisedly well! My co-workers who are also professional video producers were also very impressed! That extra full stop of light is going to really come in handy in low light settings! Awesome value for the money! I plan to buy another for my B cam. Definitely recommend it!

    Muy buena solución para poder utilizar objetivos Canon con la bmpcc 4k, la uso con el 50mm el 70-200 y el 28-135 sin embargo no tienee la función de enfoque con ninguno, solo el estabilizador del propio 28-135 funciona, fuera de eso es una opción excelente.

    3rd time, where's my charm?

    Reviewed in the United States on July 11, 2018

    Length: EF-M2IIVerified Purchase

    *Updated*
    This is the second one I've gotten from Amazon and the 3rd I've tried. This one will not even manual focus below F5.6 on an F2.0 lens. Metabones works 100% of the time. Sorry VILTROX I tried.

    ——
    Did not work with any manual lens. Gave me a 'Lens Attachment Failure' message with all my manual prime cinema lenses. No error with AF lenses but it froze the camera way too often to be reliable requiring the battery to be pulled to reset. When it wasn't freezing it caused erratic behavior with my Sigma lens. It would jump into focus zoom randomly in manual focus, and in autofocus and it would reset the aperture to a minimum whenever I half-pressed the shutter button.

    I really wanted this to work. I don't want to drop $700 on another Metabones.

    Preliminary Review: Autofocus works but has some issues, very loose mounts, decent image quality

    Reviewed in the United States on December 25, 2017

    Length: EF-M2IIVerified Purchase

    I haven’t tested exhaustively but felt it was important to note that this adapter is not an equivalent in image or build quality to the metabones versions. Adapters generally aren’t known for stellar mount rigidity, but this mount is unacceptably loose on my gh5 and gx85 with a sigma 35 f1.4 on both ef AND mft sides. Construction of contacts looks a bit dodgy as well, but the autofocus mostly works, and image quality is ok, al little glowy wide open, not as clean as the metabones. For the price however, I’d say it’s ok so far as it’s a unique value proposition, but I wouldn’t pay more than $220 for it and say that you get what you pay for.

    Works well with tge BMPCC 4k. If you can’t get a solid focus, spin the glass element inside and it should help. There are videos on YouTube that show you the way. Much better value than the Metabones, especially till they come out with a specific product for the pocket cinema camera.

    Pienamente soddisfatto

    Reviewed in Italy on November 30, 2019

    Length: EF-M2IIVerified Purchase

    Questo è il secondo VILTROX EF-M2II che acquisto.
    Uno lo utilizzo con la cinecamera Z CAM E2 e questo con la Panasonic Lumix GH5.
    Conscio del fatto che un Metabones sia otticamente superiore a mio parere credo che la differenza di prezzo (circa 4:1) non sia giustificata.
    Riguardo la differenza della qualità finale dell'immagine preferisco utilizzare il Viltrox del quale va sottolineato che oggi viene venduto nella sua seconda versione (M2 II) che differisce dalla prima versione (M2).
    Il fattore di moltiplicazione dichiarato (0.71) è leggermente superiore a quello reale (circa 0.7) perchè il campo inquadrato è leggermente più ampio del metabones (ho avuto modo di fare delle prove sfruttando l'amicizia con alcuni amici videomakers).
    Su questo item non'ho riscontrato problemi di messa a fuoco all'infinito (fortunato) ma in caso basta ruotare con le dita (con attenzione e delicatezza) il sistema ottico centrale che è semplicemente avvitato e non'ha viti di blocco (operazione che richiede tempo ma i risultati sono garantiti).
    Ve lo dico perchè sul primo Viltrox ho dovuto agire in tal senso.
    Meccanicamente solido, otticamente un pelo meno definito del metabones ma comunque più che accettabile, anzi in abbinamento a macchine che restituiscono un immagine contrastata e dettagliata quel tocco di leggero "sfumato" dona alla scena una sensazione più "cinematografica".
    Ho trovato installato il penultimo firmware (Ver. 3.3) che era anche l'ultimo fino a pochi giorni fà e l'ho aggiornato alla versione 3.4.
    In abbinamento alla GH5 tutto sembra funzionare bene con le ottiche in mio possesso (TAMRON, SIGMA e Canon).
    Il costo non'è elevato se rapportato a quello del metabones e nel mio caso il funzionamento è sufficiente a rendermi soddisfatto dell'acquisto.
    La gestione dell'AF potrebbe essere più veloce e precisa ma a parte questo non vedo grossi difetti e/o problemi.
    Anche il serraggio delle baionette è buono e non mostra gioco meccanico e nemmeno un serraggio "esagerato".
    Non consiglio e non sconsiglio questo prodotto perchè tutto dipende dalle Vostre esigenze ed aspettative.
    Se volete la qualità assoluta dirigetevi sul metabones ma spenderete più di ottocento euro … altrimenti prendete questo a circa quattro volte di meno senza aspettarsi perfomance ottiche di "riferimento" anche se per me sono più che decorose.

    Niveau qualité de fabrication c'est haut de gamme. Après 180 euro quand même c'est normal; je me demande vraiment à quoi ressemble le concurrent bien connu à 600 ou 700 euro !

    Niveau AF, sur l'objectif canon ef + 1 sigma, cela fonctionne bien; même si l'af est un poil moins bon qu'en reflex "normal" mais rien de bien grave sauf si vous voulez faire de la video pil poil mais bon dans ce cas on passe en général en manuel de toute façon pour eviter l'effet de pompage (sauf si vous avez du haut de gamme)

    concernant les objectifs EF-S cela ne marche pas (comme annoncé)…. sauf si vous êtes ok pour virer la petite partie en plastique au cul de ces objectifs et là c'est bon ! (ca se reclipse mais bon; à réfléchir c'est limite)
