It’s in regards to the new a7 IV, that has a (by Sony to house owners confirmed) extensive aperture shut distance Eye-AF entrance focus challenge (like body filling face, or head- and shoulder portraits), which makes the AF to deal with the attention brows or eye lashes solely, however to not the pupil – even when the main target body does mark the pupils completely.
The spot-AF with deactivated Eye-AF isn’t affected, so it appears to be a software program challenge.
Additionally many homeowners did a comparability with their a7 III, a7R III (I did), a7C and even the a7R IV and none of them did present this challenge and nailed the pupil in the very same circumstances by largely 99%, whereas the a7 IV did miss 50% on good days and usually miss 75-90% and the opposite 10% have largely been solely acceptable.
Many (together with Sony) blamed affected customers with person error, DOF and aperture feedback. However the humorous factor is, that additionally a professional photographer who was making an attempt to make images for a watch lashes extensions catalogue had this challenge – with aperture F6.3! There have been some extra affected professional photographers as nicely.
Sony denied this challenge for a very long time however we might make some strain and nonetheless do, which appears to work.
We’ve constructed a neighborhood to share experiences, share serial and case numbers and proves that it is a significant issue, that each proprietor can level to when opening a case.
Most significantly: We have already got 3 confirmations (2 acquired in the present day, confirmed in Romania, Australia and Germany) from Sony and a reseller with an personal Sony rep that might reproduce the difficulty along with the shopper and totally different Sony lenses.
We’ve made them public and Sony instructed 2 of those house owners that did get the affirmation as nicely, that there will probably be a communication on their web site quickly and a firmware replace that can deal with this challenge is on the best way.
