Review on 📷 Rokinon Black RK21M-E 21mm F1.4 ED AS UMC High Speed Wide Angle Lens for Sony by Chris Hanson

Cons: It looks cheap and doesn't fit as tight as I was hoping. When installed, the lenses have an easy time. BUT like all my fitted lenses, so it's not that big of a deal. Pros: Sharper than any other lens I own. Sony 50 1.8 is pretty sharp, maybe just as sharp. Of course, the lens has a manual focus, no problem for a camera with focus peaking. At f8 and set to infinity, everything is very sharp anyway, so you don't even have to focus on something a few meters away. Sony's crop sensor is actually a 31.5mm lens - it's close enough to the focal length of your iPhone that you can use it to roughly see what you're looking at. I bought this lens because it is much faster than Sony. 18-105g at maximum aperture of 4 - this corresponds to a maximum aperture of f1.4 - very comfortable to use at 1.4 but looks almost perfect when closed, it is much wider than the 50mm 1.8, which is 75mm equivalent and it has very little distortion, the attached images have not been corrected for distortion. I will say that the way it renders the image is much nicer than the 18-105g which often looked dirty. This lens is sharp. By price? I don't think it can be surpassed. I was torn between this and 12mm f2 - I think I'll buy both.
