TTArtisan 21mm F1.5 Full Fame ASPH Wide Angle Lens for Leica M-Mount Cameras Like M2 M3 M4 M9 M10 Black

Not only is this a good lens for the price but a good lens overall. Yes it may not have manual focus and the minimum focusing distance might not be the greatest but this lens will teach you to be a better photographer. It doesn’t take long to learn how to shoot with manual focus and once you do learn you’ll get some shape images. Definitely worth the money in my opinion.

Not really using it as much as I thought I would. Really comes in handy for some close up filming in low light situations where I don't need the extra fine detail. But the combined low focal length with the budget quality makes it where the middle is the sharpest point and even there the quality isn't great, it's really only the center too. Gets pretty bad around the frame. But it's good for the price since it's fast and it's very hard to find anything similar at this price point.

Perfect lens for wide angle landscape photography with my Z6. Manual focus, but a 1/4 of the price of the Nikkor 20mm. Love this lens!

Una lente fantástica. Muy luminosa f1.5 y con gran nitidez tanto en el centro como en los bordes. Diafragma de clics que facilita el ajuste. Válido para montura E full ftame y Aps-c. Fácil de enfocar. Estoy encantado con la lente.
