Hi Bo-Ming,

I saw that my 24-85mm been modified with the the AF still 'F'. Does it mean that the AF failure can not be fixed, or the database has to be updated yet?

Thanks,
Frank

Hi Bo-ming,

I have tracked my 70-200mm lens record and found it failed the AF test. Does this mean that the lens can not be converted? Any work can be done to make it work?

Thanks,
Frank

I guess that the f/3.2 side will cause the exposure a little underexposed and f/5.0 overexposed. If my guessing is correct, I would rather have tiny underexposed pictures.

Thanks Bo-Ming. This solved my long term confusion. I thought that the actual lens opening were 5.0 instead of 4.5 made from the lens manufacture.

Thanks again.

Bo-Ming,

If you have success with 70-200mm, would you please tell us whether the max f stops keep the same, which is still 3.5-4.5?

Thanks,
