Note: I have already reviewed the 25mm f/1.4 CCTV C-mount lens on my Nikon 1 V1 – you can read the review here. Because of borderline unusable image quality on my Olympus OM-D E-M10 I have decided to write this review, in course of which I will be analyzing its performance on Micro 4/3.
In the original review I have made the argument that this no-name 25mm f/1.4 CCTV C-mount lens isn’t worth getting, unless you are a huge fan of swirly bokeh and other “Lo-Fi” effects usually associated with Lomo and Instagram. This is even more so when you use this lens on a micro 4/3 body. This is unusual, since its cousin, the no-name 50mm f/1.4 CCTV C-mount lens, performed much better on the larger sensor of the E-M10.
Anyway, this review is more of a warning than anything else. Read on to find out why you shouldn’t get this lens.
