If your looking for a low light lens for photo or video look no further. I shoot in nightclubs and needed a 1.4 lens so I didn't have to use a LED light to catch all the details. This lens works great! The lens is super sharp and the low light performance is out of this world.

I had done enough research to satisfy my curiosity about the product and was not disappointed in it at all. It does what it says it does and that's all there is to it. The lack of autofocus might be a problem for some but it is clearly labeled and marketed as manual focus so this shouldn't be a...

I love this lens! The bokeh circles are nice and flat, without any rings or dimples. Images look sharp, and build quality is excellent. My only complaints are the lens cap doesn't fit very well, and you have to remove the cap to take the hood on or off. For the price, this is a stellar lens.
