Hi all, I have just finished writing a blog on how to fix a Metabones adapter without dismantling the unit. With the purchase of my A7R I received a free adapter as a redemption offer from Sony Australia. I did a lot of comparison testing against several adapters that I had previously used with a Sony Nex7. My tests proved that the Metabones causes flare under certain lighting conditions. For example, long exposures with overcast skies, and around rainforests, waterfalls, with night shots and architectural interiors.

I also use a King adapter (bought it to replace a malfunctioning metabones MKII) and it works well. I have the AF model, and it has internal baffling and works as it should -- the construction is very similar to the metabones one, too. I think I paid ~$160 on eBay, and have been using it with a TS-E 17mm with great results.

Why not just use the pixco then? Where did you find it pre-flocked?

I have both the King and Metabones III adapters (Metabones was half price when purchased w/ A7R but still pricier than the King at full price!). I actually prefer the King. It mounts on the camera without having to get a pipe wrench to lock it in place (or remove it)! Both of them fit snuggly and are solid. I also have another totally manual EOS-NEX adapter, a no-name Chinese unit, that fits loosely on both the camera and lens. I think it cost about $20 and isn't worth even that!!

So I got the Mark 4 metabones adapter (ordered directly from MB). A few observations:
1. It now comes with a protective plastic case and two end caps - which should be nice - to prevent dust gathering in the optical path.
2. It's tolerances and quality is pretty much as bad as before, the adapter still moves slightly when mounted on A7R.
3. The inner path does appear larger and it does reflect much less. Putting the two side by side by a light source makes it pretty apparent.
4. So far I tried 24-70mm mk2 on the new adapter, and I have been unable to induce vertical flares (i.e. coming from light just above or below the frame). MB3, with top and bottom unflocked, does exhibit flares from the same spot. I was able to replicate side flares, but they were weaker than a flocked MB3. Haven't tried TS-E 17 yet.

I'm actually thinking of swapping the two mount ends from MB3 to MB4 - but I guess I can contact Metabones first. My MB3 had a perfect lens-mount side tension.

The side flares on unlocked 4 are less than a flocked 3
So you will need to just flock the sides on you version 4?

Yea I may need to do that. Though its also possible side flares are not really adapter related, but I'll have to test that before I bother flocking.Mark 4 is certainly an improvement though I really can't stand build quality.

Anyone tested the new Canon 16-35/F4 on the Sony A7/7r yet? Based on the MTF performance this lens might be significantly sharper than Sony's upcoming 16-35/F4....

Here's a thread from the Alt forum that discusses this lens.

yes: http://www.fredmiranda.com/forum/topic/1302020/2

It might be sharper but you always loose something with the adapters. No free lunches and whatnot.

Thanks for the pointer -- the big question now is how it compares to the Sony lens.

Just like Nikon outsources sensors from Sony, Sony should outsource lenses from Canon

So far I didn't lose anything with the use of adapters other than slow AF which is no issue for me since I use MF with the A7R anyway. Just opposite, I only gained by using the A7R and adapters in incredible resolution and DR! And of course in the flexibility to use all kind of MF lenses.

I found the metabones/A7 auto focuses as fast and accurately as Canon's 5DIII live view, ~2 seconds. Certainly sluggish by dslr standards, but fine for most things not moving quickly. I still have my dslr for bif and children, not sure which are faster at times!

A7(R,S) owner, what to replace your A7 series? I can't think of any for now. I am in love with photography all over again just like my 1Ds2 in the old day.
