Depends on what you define as "works well"... I like my Canon 100-400 II very much, but I don't expect it to simply AF on a fast flying bird at 400mm. Using my bag of tricks, I can do a lot, but ...

In my case, the lenses which wouldn't fit were the Canon 70-200 L (both versions) and the Contax Zeiss 100-300, at least not in the "ready to shoot" state (with adapter and non-original short hood). ...

I tried the 1.4x only briefly. The impression is similar to without, but more so: that at the longest FLs it can be hesitant and search in some situations. Basically it "works", but I still haven't ...

I use it, it mostly works: with A7RII + MB IV at 400mm, small to medium small focus changes are very fast. It's when you move from something close up to something far away (or the other way ...

Though the vast majority of the lenses I'm using on said high megapixel bodies are more than 10 years old, and don't have very uneven corners, very visible decentering and so on...

Also have the Horizon and like it very much. Comfort is at the level of good "serious" mountain packs. Only real drawback it that longer lenses (most 70-200s and so on) won't fit upright in the ...

When I had the Commlite adapter, I also had many focusing and stabilty problems because of lost contacts. Basically, the Commlite uses *very* bad quality electric contacts. The problems ...

That is nearly exactly the situation that it was in a place I won't mention ca. 1933. Unfortunately what followed was a case study in how mostly perfectly nice and ordinary people could be made to ...

At least with my non-original battery grip, the camera drains the less charged battery before starting to use the other one. Just swap out the partly discharged battery whenever you get the chance ...

Nah... more like a self-driving Ferrari! :-) BTW: if I sold all my adapted lenses of one brand only, I could probably buy *all* the FE mount lenses with the proceeds (except maybe the Otuses), but ...

Very nice series, I think it took quite some courage to take those pictures while not being one of the "True Believers". Very difficult to say anything else without crossing the line over to ...

Funny, I find adapted lenses more enjoyable to use as well as photography which isn't dependant on "featurez". So you're saying that a lens which depends on electric contacts, various servo & SSM ...

And BTW, the LA-EA4 AF adapter works beautifully on ALL A7x cameras, including the original A7 (where I use it often).

IIRC, the new A7II firmware has changed all that. Feedback from a more recent A7II user could be useful...

Unfortunately I've used up my rasberry, but your statement is also based on completely false premises. You're assuming that everyone who uses AF absolutely needs the absolute fastest speed and ...

Cutting to the chase, the differences are probably mostly about which software one is most used to or knows how to use best. Someone who has been using LR for years is simply likely to prefer LR, ...

The most appropriate answer to that: <Rasberry>...   😂

The lenses you can mount keeping AF: Contax N Zeiss lenses - expensive adapters and some caveats regarding the lenses themselves. For enthusiasts only... Sony/Minolta A mount - some very nice ...

My own opinion of Color Foto's test results and ratings is pretty poor (or at least I find them wildly inconsistent)... I'd certainly hesitate to call them "the most serious", though there actually ...

Reading your post, I can only think that either you've had unusually bad luck or that one or more of your lenses is putting abnormal stresses on the adapter. I have 3 Novoflex adapters (and tons of ...
