So I finally got this little Chinese lens - 7artisans 25/1.8, Sony E mount:
Once again I'm shocked by image quality by Chinese lens out of nowhere.
Sony NEX-6, wide open, no post-processing besides resizing.
Minimal focus distance, still wide open:

Yeah, close focus center sharpness looks good. But what about in landscape mode (infinity, f/8 ), is it sharp to the corners? _________________ my flickr stream |

I'll check when I have some light .
Meanwhile take a look here, it's 1:1 crop from the very edge of the first photo (wide open). From what I know it's nearly as sharp as Nex-6 sensor is able to detect.

I've got also Fuji X version. It delivers as well. Shoots from Fuji X-M1, no post processing besides resizing. By the way, Fuji jpgs can challenge Sony ones, look how they pop.

Besides, I can also imagine the employees in e.g. Germany and Japan being better paid and better treated than employees in some Chinese production environment. |

The English term you're looking for is, I believe, a "loss leader" strategy. I expressed the same sentiments before but when you think about the market, and historical prices, and the contemporary demand for quality, not much has changed. Another member made sensible points about it: http://forum.mflenses.com/two-meike-e-mount-lenses-on-the-a6500-t77603.html |

I got mine a few weeks ago, and also took it on a short vacation. It's a very versatile lens. At f/1.8 it remains useful for night time street shots. The very short minimum focus distance is convenient e.g. for dinner-shots.
On 2 days of the trip, my kit was the 7artisans 25, a Summicron-R 90 and a Samyang 12mm. This proved a very solid kit covering everything I may want to shoot. |

Yes! Fantastic.
Delivery of this lens (for my X-E2) is pending. I was looking for a good and still affordable lens in the 23/24/25mm focal length area and finally found a mint copy for a very good price. _________________ Personal forum activity on pause every now and again (due to job obligations)!
