I’ve had my new lens about 3 weeks and taken photos in various venues at various focal lengths. I also have some photos where I used the Sony e-mount 1.4X converter in conjunction with the lens at 400mm to give me an effective 560mm lens. I found the lens with the converter was still very sharp. With the converter, the camera in “Auto” mode tended to chose 1/500^th of a second, which I found to be a bit slow, especially for moving objects. I used it in shutter priority mode at 1/600^th of a second for better results.

This is not intended as a review but I was very happy with how lightweight and compact the lens is even with the 1.4X convertor. Much of my shots are while I hike on trails where a tripod is not suitable. All of these shots were hand held. I had the 2X converter but found the photos to not be as sharp as I would like and returned it.

While Sony will be coming out with a prime 400mm 2.8 lens soon, my bank account will not allow me to purchase it and my cardiologist will not allow me to carry it. I traded in my Metabones adapted Canon 400mm f4 D.O. lens and have never looked back.

I have not had any auto focus issues with the lens even with reduced light using the 1.4 converter.

Now all of my A7R2 lenses are e-mount and I am “adapter free”. Thanks Sony and Zeiss for finally filling out the range of lenses that fit my wildlife and landscape needs. Glad I have this lens. I carry it mounted to the camera hanging on my shoulder from a Promaster Swiftstrap mounted to the tripod foot.
