The Samyang 21mm F1.4 ED AS UMC CS is a nice wide angle lens, with good image quality from edge to edge, even wide open. Being a bit wider than the 23mm lenses, which Fujifilm offers, either with a similar f/1.4 aperture or as a more compact f/2, the Samyang 21 still is an interesting and affordable alternative to the two Fujifilm lenses. The 21mm focal length is similar to an untraditional 31.5mm on a full frame camera, or 69.3 degrees angle of view. It is a bit wider than the classical 35mm, but still not too wide, even allowing you to be more flexible in tight spaces.

Second, the width of the lens is very wide, which means that creating a composition which will emphasize the subject, will be a challenge. This is a creative lens, which needs to be used for creative purposes by creative shooters. You will need to think outside the box, whenever you put this lens in front of the camera. But when you do, and you learn to use it properly, you will have a lens which is fun to use, and which gives you results you ot...
