Hi, thank you for contacting JustAnswer.com. My name is Russell. I regret that your case waited so long for a response; I will do what I can to provide the right answer to your question.


If I understand you correctly, the DT 35 mm F1.8 sam lens does not do exposures correctly with your Sony A35 camera, but a 75-300 lens (of some unspecified type and maker) does work.

I want to be sure that I do not give you incorrect advice, so please tell me explicitly:

- Is the DT sam lens one made by Sony?

- How old is the DT sam lens?

- Is the 75-300 lens made by Sony also? and what model is it, please?

Thanks.

Both lenses are made by Sony and are both under 2 years old
Expert:  Russell H. replied 3 years ago.
Your camera is compatible with some Sony lenses. Some of them are AR lenses.

But the exact model # (of the lens) is needed, please, to make sure this isn't just a compatibility problem.
Customer: replied 3 years ago.
The F1.8 lens came with the camera
Expert:  Russell H. replied 3 years ago.
The lens compatiblity for your Sony Alpha A35 camera, covers only certain lenses.

All of the compatible lens types have model numbers beginning with

SAL-1...

except one, the SAL-50F18.

Please try to determine whether you have a Sony-made SAL lens. And what its model # is.

If it is not a Sony-made compatible lens model, the compatibility may limit the performance, of course, in just the manner you have observed.
Customer: replied 3 years ago.
The lens which came with the camera was
DT18-55mmF3.5-5.6SAM
Expert:  Russell H. replied 3 years ago.
It sounds to me as if the lens that came with the camera either was defective from manufacturer, or has developed a defect in control/performance.

Remove that lens, and with a soft clean dry lint-free cloth, rub the electrical contacts (copper-colored, on the lens, designed to match those on the lens mount) off gently. If this does not aid in the problem, then you have a defective lens as far as I can see, and you might have to either have it repaired, bear with the problem, or replace the lens - according to your preferences and priorities.


Please rate my Answer - hopefully, favorably - in order that I may be paid for the work I have done on your question. Thanks.
