7artisans25Mm F1.8 Aps-C Large Aperture Manual Focus Fixed Lens For Olympus And Panasonic Micro Four Thirds Mft M4/3 Cameras - Black

I was not expecting to get lens with no deference between Aperture value, in this lens there is no deference between F2.8 and F1.8 while fixing the iso in Aperture priority shutter speed remained same between F1.8 and F2.8, this design show its failure in design, since Aperture Blades is reaching the maximum opening in f2.8 and remaining Aperture will not effective.The positive point about the lens is sharpness, it's very acceptable to me,Overall just fine lens.

Lente muy versátil, manual.

Acheté sans grande conviction, je me suis dit que pour le prix je ne perdrai pas grand chose. Hé bien non seulement vous ne perdez rien mais vous gagnez un petit objectif de bonne qualité de construction qui fait largement le job pour des amateurs et même amateurs avertis. Attention tout de même dans les petites focales mais le résultat reste correct et devient bon à partir de F4.Un très bon produit pour se lancer dans la focale fixe sans se ruiner.Je recommande dès lors que vous êtes conscients d’avoir un objectif à moins de 100€ en main !

Don't be fooled by the cheap price. The built quality and results are excellent. I've been wanting to get a prime lens for my Lumix 4/3 mirrorless camera but the prices have always let me down because as a video documentary maker, a prime lens is not my most needed accessory. I'm so glad that 7Artisans has brought out this lens with a price that I can afford. Now I have a prime lens that I can use for close-up work when it becomes necessary. The absence of auto-focus is not a deal breaker because most professional photographers and videographers prefer manual control of the focus.

En mis pruebas, este objetivo es claramente superior al del kit 14-42 mm Panasonic Lumix G7 (en la distancia focal de 25 mm). La resolución es claramente superior. Buen contraste. No le he encontrado aberraciones.Para vídeo y macro es genial (equivale a un 50 mm en full frame). Si no puedes vivir sin autofocus y no te gustan los modos manuales, no es tu objetivo. En caso contrario es una joya a un precio de risa.Me gustaría: (1) que el anillo de enfoque tuviera mayor recorrido. En cuestión de décimas de milímetro cambia todo. (2) que no diera trabajo ponerlo y quitarlo. Hay que darle (con cuidado) atrás y adelante hasta que logras sacarlo. Tanto al ponerlo como al quitarlo, la única zona en que se puede sujetar para ejercer fuerza de torsión es un segmento muy estrecho entre el anillo de enfoque y el de diafragma.Vengo de una experiencia decepcionante con otro 25 mm 1.8 de precio similar y otro fabricante, y este, en contraste, ha sido una gran sorpresa agradable. Mi recomendación absoluta para quienes disfrutan controlando la exposición y el enfoque.

Amazing bargain! Very nice image quality, well made. Small lens for Olympus m4/3 system. Works perfectly on an OM-D e-m 10 M2. From an image quality point of view you might get similar results with vintage glass, but the required adapters will make the camera a lot bigger. Also, you will have problems finding a focal length that compares to the 25mm 1.8. This lens will produce nice results. Highly recommended!
