I had never heard of this product before. It looks like Sony no longer makes the video binoculars. There are other manufacturers but the reviews are mixed. I believe the zoom feature is digital not optical which means the photographs will not be optimal. Thanks for your response that was also enlightening.

I don't see myself trading in my Canon lens toward this new Sony lens primarily because the new lens is not well suited to using the 1.4X and 2X teleconverters on the A7R2 and I don't need the lower part of the magnification range for wildlife. I believe Sony will come out with an fe prime lens or variable lens at or above 400mm and can wait. I understand the new A9 would work well with the 100-400mm lens and 2X teleconverter because it can autofocus to f11. The problem is the cost of the new A9 and it is only 24mp so there is no room for cropping and a lesser quality photograph than the A7R2. If Sony comes out with an A9R, that may change my thinking about changing for the 100-400 and A9R. Time will tell.Dale Matsonhttps://www.blogger.com/profile/12975212053636312471noreply@blogger.comtag:blogger.com,1999:blog-2659229161342692060.post-14637337267575217312017-03-17T04:23:46.489-07:002017-03-17T04:23:46.489-07:001.

I cannot say enough good about the superior performance of the Metabones IV (.41 firmware) T adapter with excellent autofocus in phase detection. There is some hunting when using the 1.4 extender and it is useful to 'prefocus' first.<br />I also have the Canon 70-200 2.8 lens (version 1) with excellent autofocus using the Metabones adapter and no autofocus using the Viltrox adapter. Brian Smith has a superb article on using the Canon lenses on the Sony A7r2 and the performance with the Viltrox, Metabones and Photodiox adapters. It is clear from his article that the Metabones is superior with almost every Canon lens and worth the extra cost. http://briansmith.com/sony-a7rii-canon-ef-smart-adapter-tests/Dale Matsonhttps://www.blogger.com/profile/12975212053636312471noreply@blogger.com
