I understand the feeling of wanting the best experience but i think your ignoring the negative been said about the V3. And making it look better than it was.
much improved usually mean there are still some
For sure the review where made in a positive manner and excitement. I would be curious @Cdaked to know if you think after all this time if the lens version 3 was shipping ready. I could go in length on how some of the problem in M1 could have come to be but plenty of ppl have already said it and it clearly didn’t change your opinion and i guess that is fine.
But on a pure logical standpoint, it make no sens for a company to keep on developing and spending resource on a part that is good and ready. So my only conclusion is they where missing something they needed to improve and that brings them other problem that need tweaking. They also look like they believe they can still improve it and are doing it.
To answer directly to your title. What happened to V3 is that they are still trying to improve it
Sorry for ignoring the worry some have expressed that V3 could have been overly costly version that never would have been possible. I just don’t see the point of going down that lane. Wont help anyone.
