Sony E 10-18mm f/4 OSS Lens with UV Filter Kit

Sony E 10-18mm f/4 OSS Lens is an apsc lens and those cameras are full frame, so it will work but it will crop the sensor of those cameras. Less than half of the available megapixels will be used. The angle of view will increase by 1.5x. In the camera settings you need to set it for crop mode, many times the camera goes to that mode automatically.

Both high quality lenses, however they are for different purposes. Not a good comparison in my opinion.

In situations where B&H offers both a USA and an imported version of a product, we label each version clearly and explicitly. If a product does not have an indication either way, it is understood to be by default a USA product. In situations where only a USA version is offered it will not be labeled USA.

This lens is made for the APS-C sensor on the Sony ILCE 6000 series. No good on the full frame A7 RIV.

The lens is made in China.

Vignetting typically will occur on a lens with a focal length of less than 24mm, and so it is advised to use slim filters with this lens.

As the Sony 10-18mm f/4 OSS Alpha E-mount is designed for Sony APS-C cameras and the Sony Alpha A7S Mirrorless Digital Camera is a full-frame camera, you would either have to use the lens on the camera in the APS-C crop mode (which would reduce the camera's effective resolution to 5.3 megapixels), or in full-frame mode (which will show dark vignetting where the rear of the lens blocks the sensor). In APS-C crop mode, you would not have vignetting; in full-frame mode, you will have vignetting.

This lens will be compatible with the Sony FS5.
