4 Comparison

There are not so much 50mm F1.8 APSC (75mm equivalent) available but well a lot of 56mm (85mm equivalent). You can also look at 50mm full frame F1.8 but those will be bigger heavier and more expensive in general

Il n’y a pas beaucoup de 50mm F1.8 APSC (equivalent 75mm) sur le marché mais beaucoup de 56mm (equivalent 85mm). Il y a aussi l’option de regarder les 50mm F1.8 plein format mais ceux ci seront plus lourd plus gros et plus cher en général

The 2 Yongnuo are the cheapest , the most compact and the one with the less good build quality

The Sony is the only one with optical stabilisation

The Meike is the cheapest and the lightest of the F1.4. Only the TTArtisan which is a F1.8 is cheaper and lighter. It build quality good but lower then the Sigma or the Viltrox. AF is very good but still below the Sigma or Viltrox

Les 2 Yongnuo sont les moins cher , le plu compact et ceux avec la qualité de construction les plus faible et ceux avec la distance min de mise au point la plus courte

Le Sony est le seul avec stabilisation optique

Le Meike est le moins cher et le plus léger des F1.4, seul le TTArtisan qui est un F1.8 est plus léger et moins cher. Sa qualité de construction est bonne mais en dessous des Viltrox et Sigma. Son AF est très bon mais moins que Viltrox et Sigma.

4.2 Sharpness / Piqué

Table comparing various 50mm camera lenses, highlighting their performance ratings across different aperture settings from F1.4 to F16.

The Sigma 56mm F1.4 DC DN is the best one , closely followed by the Meike , then the Viltrox

Among the F1.8 The 7 Artisans 50mm F1.8 MF provide better performances than the Yongnuo. The Sony, very old is the least good one

Le Sigma 56mm F1.4 DC DN est le meilleur suivi de près du Meike , puis du Viltrox,

Parmi les F1.8 , le 7 Artisans 50mm F1.8 MF est le meilleur que les Yongnuo. Le Sony très ancien est le moins bon

4.3 Bokeh & Color rendition / Bokeh & rendu des couleurs

  • Results are mostly similar in term of Bokeh Balls / background blur softness and color rendering
  • The shorter min focusing distance and/or with a F1.4 makes you can obtain much bigger bokeh balls on the Sigma. The Meike has a quite a long min focusing distance
  • The color rendering is better on the Viltrox with a little bit warmer tone and well balanced contrast. The Sigma is a little bit cooler and its (too) high contrast makes you need then to boost the shadow to get some details in the dark areas.The Meike has a good balance in term of color rendering and contrast.
  • Les résultats sont équivalent entre les , Sigma, le Viltrox point de vue ronds de Bokeh (bons),
  • La différence de distance de mise au point minimum fait une grande différence sur la taille des ronds de bokeh que l’on peut obtenir , nettement plus grande avec le Sigma qui a en plus une ouverture de F1.4. Le Meike est désavantagé avec sa distance min de mise au point de 61cm
  • Le rendu des couleurs est meilleur sur le Viltrox qui est un peu plus chaud et qui a un contraste plus équilibré. Le Sigma est plus froid et son (trop) grand contraste fait qu’il faut souvent augmenter le curseur des ombres pour récupérer du détail dans les zones sombres. Le Meike est bien équilibré point de vue couleurs et contraste.

The Sirui is the one giving the best flattering portrait but with a bit softer images, the Sigma is the most versatile and globally the most performant and best balanced. The Viltrox and the Meike are the next best one. The TTArtisan is last

4.5 Distortion / CA / Vignetting / Flare

  • The Meike, Sirui , Viltrox, TTArtisan have less distortion than the Sigma but has this one a a lens profile in Lightroom it does not really matter
  • The Chromatic aberrations are more important on the Sirui and the Viltrox compared to the ones of the Sigma, Meike and TTArtisan
  • The vignetting is a bit more important on the Sirui due to the F1.2 aperture then roughly equivalent
  • The resistance to flare is average on all the lenses but the Sigma is a bit better than the others
  • The Sun stars are better defined on the Sigma

Distorsion / AC / Vignettage / Flare

  • Les Meike, Sirui et Viltrox et TTArtisan ont moins de distorsion que le Sigma, mais comme celui ci bénéficie d’un profil intégré à Lightroom cela n’a pas trop d’importance pour les différencier
  • Les aberrations chromatiques sont très élevées sur le Sirui et Viltrox et faible sur le Sigma et le TTArtisan et le Meike
  • Le vignettage est présent sur les 4 optiques mais forcement plus important sur le Sirui à F1.2 et diminue de la même manière
  • La résistance au flare est moyenne sur toutes les optiques mais c’est le Sigma qui s’en sort le mieux
  • Les effets d’étoiles sont mieux définis sur le Sigma

4.6 Autofocus

Viltrox and Sigma are very close : very fast, accurate 90% of the time, efficient in low light. They both a a few missed shots in same proportion. The Meike is just after with the Yongnuo V2 . The TTArtisan and Yongnuo V1 are less efficient with 20-25% missed

Le Viltrox et le Sigma sont très proches : très rapides, précis 90% du temps et efficace même en basse lumière. Le Meike est juste après avec le Yongnuo V2 . Le TTArtisan et le Yongnuo V1 par contre ont un taux de déchet proches de 20-25%

4.7 Video

  • The lack of aperture ring makes more shake and noise is visible when you change the aperture on the TTArtisan, Sigma, Yongnuo, Sony . The Viltrox and the 7 Artisans with theirs clickless aperture ring are much smoother and silent , the Meike thanks to its aperture ring is also handy for video
  • The colors are more cooler and more contrasty on the Sigma, the Viltrox and , the Meike are more flattering and give more details in the shadows thanks to its tiny lower contrast. Then we have the Yongnuo and the Sony. The TTArtisan is good but a little bit dull
  • Comme le TTArtisan, le Sigma , les Yongnuo, Sony sont dépourvus de bague d’ouverture, le changement d’ouverture via la molette du boitier introduit des secousses et du bruit, le Viltrox et le 7 Artisans MF avec leur bague d’ouverture sans clics permet une image plus stable , moins de bruits parasite et un changement d’ouverture en continu. Le Meike n’est pas trop mal avec sa bague d’ouverture avec clics.
  • Le rendu des couleurs est plus froid et plus contrasté sur le Sigma. Le Viltrox et le Meike offrent des tons plus flatteurs et un contraste légèrement moindre qui lui permet de donner plus de détails dans les ombres, suivent les Yongnuo et le Sony , le TTArtisan est le moins bon

6 Conclusion (English)

The Yongnuo 50mm F1.8 DA DSM II , is a clear upgrade from V1 ( Yongnuo 50mm F1.8 DA DSM) in term of AF and color rendition , the rest stay mostly the same with overall very good sharpness, good resistance to flare, low CA, and nice bokeh balls wide open for a budget lens.

At this price with AF there is no real competitor ,

If you are ready to go MF then the 7Artisans 50mm F1.8 (89 euros) is cheaper and a little bit sharper.

If you are ready to pay a bit more then the Meike 55mm F1.4 (199$ / 259 euros) is the cheapest 55mm f1.4 and offer very good performances for the price with very good to excellent sharpness, very good color rendition and very good bokeh balls with a very good AF even if not on par with the Sigma.
