Just leave that bird alone and look for a slower bird.

Thanks everyone for your thoughts, I bought another copy of the lens, and it works perfectly with all adapters.

There is no way to do that, impossible to use Sony E mount on Nikon, that is my understanding, unless I slept 100 years and waked up to read your comment.

In Sony camera there is no flash in silent mode,will not fire at all, and I think it will be the case with Nikon D850.

Yes, but as I mentioned the focusing is not the only purpose for EVFs, also when I use live view on my Nikon D810 I do that for focus accuracy, or better face detection, not speed. Probably it is ...

Now when live view focusing is getting better and better, the only thing that I miss in classic dSLRs compared to my A7Rii is the excellent EVF, especially in bright sun light, both for framing  , ...

I love this lens, it works on a mount without problem, but when I put it  on E mount cameras (a7rii, a3000, nex-5) with adapter, it locks up the camera, it doesn't act even as a dump lens, ...

What I mentioned was a real story .

I wish I had Fujifilm GFX 50S and 120mm f4 to try macro photography, don't laugh at me, that is the point of the video, and most buyers of this expensive thing are that kind of people, please help,...

Do you think so? Sigma made E mount lenses long time ago, I have the Sigma 60mm 2.8 that works perfectly on my a7rii, and there is no difference at all between E and FE except coverage.

there are Vello and Commlite ( Commlite CM-ENF-E(1)) adapters that fully function with auto focus, some lenses are very slow, some are acceptable, don't expect the speed you get from your Nikon ...

Just buy a Sigma mc-11 for your Canon 16-35/4 For landscape you don't need fast, or even slow AF, and your lens is better than most primes at that range, I am using it on my A7RII. There  is ...

How about drones? there is one universal rule in courts, who spends more money almost always wins, of course the winner is the lawyer and both sides are losers.
That is the reason many people don't...

Don't worry about the lens, I left lenses in direct sun for one week to kill fungus.

Thank you, I did it successfully .

Can you please explain how?

It actually happen , here is a rare mc-11 for sale on ebay The bad news, just tested my Canon 70-200/4 in bright sunlight, and it is the same as low light, almost useless.

This is not a real title, but someday we will see that MC-11 with older version  firmware will sell higher than a new one, because it is impossible to go back to the older firmware. Now when I ...
