Does it only works in manual mode with a Sony SAL-70400G2 70-400mm F4-5.6 G SSM Super Telephoto Zoom Lens?

In order for any lens to be able to autofocus correctly, the minimum aperture after the teleconverter is added must still be f5.6. Therefore this lens with either the 1.4x or 2x would be manual only.

hi, the aperture on the 70-400 is to slow. it will work with The SAL-20TC supports the G series 70-200mm f/2.8 G telephoto zoom, the G series 300mm f/2.8 G telephoto lenses, and the unique Sony 135mm f/2.8 STF (Smooth Transition Focus) lens. Note that photographers will have to compensate for their reduced light transmission by opening their apertures two steps with the 2x converter.

You can use it on Sony A7s. BUT first you need to buy the adapter ring to mount the lens on the camera. That adapter ring has M42 female thread (lens side) and male bayonet (camera side). Then the lens will work on All-in-All manual mode. I hope it helped. Zonesystem

Yes, there is only the manual zoom function which is controlled by turning the dial on the lens itself.

No. Auto focus cant work because u must put camera mode to manual , the "lens" is the scope, you must focus with the scope. Be sure to realize a collimation process to your scope , if needed, to get better results, better pictures.

It works with all my Nikkor AF-S lenses. You won't actually want to auto-focus - but you may want it to take care of the other settings automatically and manually focus to get things exactly as you want. On a zoom lens, the zoom really becomes a giant focus ring.

Hi Pavel, using the LA-EA3 lens adapter, AF will work only on lenses with SAM/SSM. This Sony SAL2875 is a SAM Zoom Lens which means that the AF will work on the said adapter. -Ely

The lens itself must have manual aperture. I returned this.model for a.more.expensive one with five settings.

It's working fine with the autofocus mode on your lens, would also work with the manual focus but you would have to preset the focus on the lens.Michael

Yes it is. I use it in manual setting with my 70-300mm lens. It does not work well with auto focus when the lens is opened fully to 300mm.

Yes, it does! In the manual mode you can adjust the exposure time, ISO, aperture and the focus (not with the hands but turning the "menu wheel"). I use an old vivitar lens so then I have to use an adapter and in the manual mode (but then in this case, the lens doesn''t have communication with the camera so the focus should be adjusted with the hand). Hope it answer your doubt.

Yes, this lens does have the option for auto focusing. But I clearly find that manual focusing is the better of the two choices. Unlike some lens, this option to change from manual to auto focusing is done by sliding the forward most ring, the one closest to the len's end back and forth. No switch. There is no automatic zoom option. You have to rotate the ring closest to the camera body to zoom in and out. I guess that is why I prefer the manual focusing. But either way, I am very happy with the photos I have taken with this lens. Hope this helps

It will only work if your camera is on manual mode. There is no communication between the lens and the camera, how it is with most other lenses.

I can confirm it does indeed work. Keep in mind you are limited to manual focusing And will also have to manually control your aperture.

Yes Mr Martin it is working but only manual mode , but don't expect a lot about picture quality... If you have old lens then you can buy this adapter....
