I am using a rented a7R II and SAL70400 with the adapter from A to E. 

 

On the a7R II it works pretty well but does not support DMF focus mode. I can live with that but not very happily.

 

Today I tried the lens + adapter on my a6000 and it tried to autofocus but really could not do it. I tried both full auto and limited auto and it simply hunted.

 

Since I had never read about that I decided to tell all of you what I experienced.

 

FYI only.

Yep SONY blocked DMF and eye AF on lenses with adapters.

 

Metabones EF-NEX IV adapter, however, gives you DMF and eye af with Canon lenses! Only 4rth version and above. 

 

All these adapters work fine only on A7R2, A7-2, A6300 and A6500. Other can use only LA-EA4 to get autofocus on A lenses...

Yep.    

   

I wouldn't quite call them "discoveries", cuz those are 

the behaviors Sony specifies for those combinations.  

   

Frinstintz, I use the LAEA3 for all my ancient A-mount

lenses, and only the functions that Sony specifies are 

operational. But it suits my needs so I bought it.

LA-EA3 works better on a6500 than on a7ii for me or Nex5t for that matter. 425 PDAF points on the a6500 sensor vs 117 on the a7ii and 99 on the Nex make a difference. LA-EA2 or 4 are required with all screw drive A mount glass regardless of body.

      Looking for an a7R mk I, (second generation)

      By NewSonyUsER · Posted

      I'd really like to find a package deal for an a7R (mk I, second generation) which includes the neckstrap and box. I've searched Ebay and currently no one is listing what I'm looking for. They either have the camera only or a first generation a7R and a lot of them don't offer the Sony neckstrap or box it came in. I know your site doesn't have a formal 'Equipment For Sale' thread and granted Ebay is a better place to sell gear but I thought I'd see if any of the members have one and would like to upgrade to a newer model but don't think anyone would be looking for one that old. The cameras I've been using are in the 20 megapixel range and rather than jumping to a 40mp camera due to file size, the 36mp that the first a7R has was appealing to me and wouldn't break the bank. I've been using Canon and Nikon but really want experience a Sony. If a post like this is undesirable for this website, I understand but I thought I would ask. Thank you.

      Any A7R iv A issues with 200-600 zoom?

      By SonyFF32137 · Posted

      Here's a good thread on the issue.... https://www.dpreview.com/forums/thread/4571046 And here is the info on the A7RIVA that maybe explains why I don't see the issue...  The change in wording that caught my attention is that the new A7RIVA brochure says the structure has been "re-examined and redesigned." Don't know, but given the text of other parts of the brochures are copied word for word, the change in text here seems significant. My reading of this is that it is a redesign of the A7RIV. In that case, perhaps the 200-600 issues are less severe with the new body.

      2 Primes or 1 Zoom?

      By XKAES · Posted

      I'd opt for a small zoom, but I must admit that there seems to be a dearth of lenses in the e-mount in the 24-50mm range -- for some reason.  I have a small 24-70mm, but that's an a-mount Tamron.  Maybe you can find something by looking at lenses slightly longer.  I have a heavy, but small 24-100mm a-mount, and Tokina made a 24-200mm a-mount.  Maybe there are similar lenses in the e-mount.  Kill three birds with one stone.
