The F stop will not show because this is a manual lens with no electronic connection to the camera, you adjust the F stop by rotating the aperture ring at the base of the lens. The camera will still meter but it will not collect data from the lens.

This lens doesn't communicate digitally with your camera, fstop/focus is all manual.

i believe this is a manual only lens. change the aperture by turning the aperture dial on the lens itself.

It never does for me, I am very happy with it. It is a nice little camera for the price. There might be something wrong with your camera. Perhaps they can send you replacement. Amazon is good doing so. I hope it helped

I have the a55 ...but it should definitely work for the a57 they're both "A-Mount" cameras ...the smaller alphas are coming out with E-Mounts

Hi there! Yes this Sony Auto-Lock Shoe Adapter ADPAMA will work properly on your Sony A57. -Ely

I'm almost sure youre lens is good. As it is a prime lens, you cant control the f-stop with the camera body, so the the camera can't detect that there is a lens attached as it would with your kit lens. Go into your camera's menu, go to the section designated by the picture of the gear. Scroll down until you see the option that says "Release w/o lens" and enable it. You should be able to use the lens now.Hope this helps!-Andrew

It attached to my Sony A65 and will attach to your A57 if you get the Sony/Minolta T-mount adapter with it. Getting the desired result from its use is another matter. It did not work well for my intended purpose, but I have to take much of the blame for that. I did not have a solid enough tripod for a lens of its length and weight and I could not focus it clearly. As a result, I missed the wildlife shot that I wanted to get. This probably could have been avoided if I had practiced with it before the moment arose.

I am sorry, but I can't help you in this matter. I have never operated nor owned the A57.

Try full automatic mode. The auto focus of this camera is not very good. You might also try to increase the shutter speed and or verify the ASA setting is OK. I hope this helps!

Make sure the "patch cord" is connected between the grip and the side of the camera base. If it still doesn't work it may be the grip is malfunctioning.

I have an A7-R and it works well. How far away are you? Was battery protector removed? Try changing battery if it still does not work.

1st, make sure your camera is in MF( manual focus) mode..I use the A57 and my AF/MF switch is located under the lens release button which is under the a57 logo, then go to your menus and scroll to "Release w/o lens" and select "ENABLE".....if that works your set, if not, then enter your menus (again, I'm going by MY a57) and scroll until you find 'LENS COMP: Shading, LENS COMP:dISTORTION ETC. and put them all on AUTO..put 'Front Curtain Shutter "ON"....Hope this helps Martin, good luck

I would say try to find a way to reset the camera to all it's default settings to see if it was just something silly you pressed/touched. If that doesn't work, check your return policy. Other than that.....um....try a hammer.

I have an Alpha 37 Sony and purchased an adapter under the Minolta name to use the FD lenses from my A-1. The lenses work fine but the camera must be operated in manual mode.

My Sony A-57 operates the same way. I bought a Opteka T-Mount adapter for a cheap 500mm lens. I had to go to the menu to allow it to release the shutter when the lens is not on, since the camera cannot detect the manual lens.
