I use this lens on a Sony FS5 video camera, and only use it for doing video interviews in 4K.When opened up to it's max (1.4) or near it, I really can't get this lens to be crisp. Have to have a sharp image to start with...
Bought the lens barely two weeks ago and I love it. I've used mostly to shoot bands in small clubs and bars. The wide aperture is perfect for the low light conditions and the images stay sharp. Focus peaking with the Alpha 7RII helps with the manual focusing. Sturdy, fast and sharp.
The lens is excellent if.... you are able to focus properly. Ideal for people with some level of experience in photography. But would not recommend for people with little or no experience. Again, just because of the no-auto focus aspect.
This lens is a great buy, low price for great quality. The build quality is excellent, feeling very solid with its all metal build and comfortable focus ring. The focusing capabilities are outstanding, with very precise measurements and relatively close minimum focusing distance.
