So that day I’ve simply returned the lens to the seller for a replacement, and my second sample performed great. It helped to quickly notice that Samyang 35mm F1.2 sample has a defect. I’ve simply put camera on tripod facing the center of Star Chart on the laptop screen. I’ve used this Siemens Star Chart PDF file from Wikimedia Commons shared by John Merlin Williams (and mentioned in another Lensrentls article).
It clearly explains how to check for misaligned lens element that is significantly reducing image quality. I’ve found great and very helpful article on Lensrentals written by Roger Cicala. Lens just didn’t match the expectations and shots looked very different from what I explored online before the purchase.įurther research discovered that lens had optical misalignment. Unfortunately my sample produced very disappointing results. It’s awesome glass with quite advanced optics tha tincludes ED and Aspherical elements. Two years back I’ve purchased Samyang 35mm F1.2 lens. I’d like to share how to check that and my personal experience trying to fix the problem. Sometimes purchased lens may produce very bad results just because it’s defective sample. But in both cases I’m expecting optics to be properly aligned and matching the expectations. I like sharp images, and I like soft images – it depends on the shot goal. Each lens has strong and weak points, and knowing that helps to use equipment in most efficient way. Typically lens are performing very close to the designed limits and producing great shots.
