For almost two years, I had been looking for a manual-focus 25mm lens for my Olympus Pen E-PL9. This after I realised that there is an internal design flaw in the Olympus 14-42mm EZ kit lens. During that time, I came across plenty of information about the 25mm lenses from 7Artisans and TTArtisan. They have many reviews, sample photographs and comparisons.
Then about a year ago I came across another option: the SG-image 25mm f/1.8. Naturally, I wanted to know how it compared. So I searched for image samples and reviews of the SG-image lens. Unfortunately, I could find very little. In fact, I could hardly find any pictures that were available at full resolution that would allow me to pixel peep.
