Dear friends, I have now had the 70-400 and the LA-EA4 adapter for more than two months and have managed to cope with erratic focusing on garden birds somehow or other. One great thing using this adapter is that the spot focusing is much smaller than the standard one and let's you pinpoint be birds head more precisely and that I love. With the standard 70-200 f4 I could focus much quicker, but many times it either focused on a branch or the legs and body, leaving the head and eyes out of focus. Lately however I've seen many comments about how much better the simpler LA-EA3 works with the newish A7RII, since it used all the more than 300 focus points plus other benefits that the camera could use on these lenses. The thing is I purchased the EA3 and tried it as soon as I laid my hands on it. Shooting garden birds from a feeder and at 400 mm (which is what I mostly do), and at about 5 m (16 feet) distance, I immediately noticed that focusing was much harder, sluggish and the lens kept hunting backwards and forwards most of the time. I have the camera set for obvious reasons at spot focus small, so I guess the 300 or so remaining focus points do nothing to help me focus, so I asked myself what was the point.... I then tried all sorts of settings to see if I could improve the focusing, even trying phase and contrast detect (contrast being a NO-NO), so now I find myself at a crossroads where I' wondering if I should return the EA3 or try and follow your suggestions on how to improve the focus with it. One thing is VERY clear; if I reinstall the LA-EA4, in the case I'm explaining here, it seems almost instant focus compared to the EA3. What do you suggest I do? I only have this zoom lens that fits both my adapters, since all my other lenses are FE mount and right now I have run out of ideas.... Have read all that Brian Smith says about adapters and was one of the main reasons for making this purchase (http://briansmith.com/sony-a7-a7r-lens-mount-adapters/) Best regards, Spanish Flyer PS.: The camera already has the 3.2.0 firmware
