From this topic by dgaies.
"FA*28-70mm hood dilemma and solution"
If DA* 200mm hood fits well with FA* 28-70mm (and FA* 80-200mm too!). I think there is another possible compatible hood for these lenses. This hood is bought 2nd hand from Ebay and thought it will fit my DA 12-24mm. It turned out that this is not compatible with DA hood thread, but is compatible with FA* and some DA* thread.
Sorry I already sold my FA* 28-70mm, so I don't have lens to test. But I hope it helps someone who is finding FA* 28-70mm alternative hood.
