A7iv with LA-EA5 iin S&Q mode allows manual focus only?

[seppoju]

Not sure if this is a user error... I use LA-EA5 and it is nearly perfect. AF works really well in photo and movie mode. But, in S&Q there is only MF available. When I try and change it in Fn menu I get "this function is currently disabled". Is this related to LA-EA5 behaviour or is there a workaround?

Hey there, restriction of the functions are different depend on the lens variation. Which lens are you using? 

[seppoju]

I've tried with all my A-mount lenses, including Minolta 100-300APO, Sigma's 70 2.8 macro and 35 1.4

Can you tell me which A-mount lenses will autofocus in video and S&Q modes, please?

Hey seppoju, these are all the compatible lenses, when you click on an A lens, it shows you the needed convertors and the restrictions:

I've tried with Minolta 28 2.8 AF, 50 1.7 AF, 70-210 4 AF and 100- 300 APO and none of those give any AF in video or S&Q mode although the Sony support page says: "

• Although you can perform auto focusing, it is sometimes difficult to focus on a subject using this function when you are shooting dark scenes or when a subject is located at the corners of the screen or is significantly out of focus."
• All the above lenses give message : This function is currently disabled. 

So, something is not correct here. Please advice!

@seppoju, if you're using a non Sony lens, non of the features are guaranteed anyways. They might work and might now work. have you tested any Sony lenses? 

[seppoju]

On that Sony support page are those specific Minolta lenses mentioned (most of A lenses are Minolta methinks), so that does not explain the issue. One possibility is that Sony support page refers to AF in photo mode - the LA-EA5/Sony A7iv combo works perfectly in that mode. If that is the case it should be mentioned somewhere....

[HannahEd01]

@seppoju, at this point I don't think I can add any further help to this thread. But I will try to explain my point in a different way. 

If you click on the AF 28-70/2.8 G lens on the above link, one of the restrictions written there is : "If you attach the [A-mount lens] using the Mount Adaptor, MF assist function does not work automatically when you turn the focus ring. You can enlarge the image by selecting [Focus Magnifier] function or [MF Assist] function to any key in the "Custom Key Settings"."

Does this make any sense? Is this what you're looking for? 

[seppoju]

Thank you so much for trying to help me, Hannah!
The operative words are "video and S&Q". All works well in photo mode, the AF is surprisingly quick and accurate.

But, the AF does not work in video and S&Q modes. It may well be that the adapter is not capable doing that, but I would appreciate it if someone ( e.g. Sony) would confirm this.

@seppoju, we've two ways to go about this now, either we try the standard troubleshooting steps and if the issue remains you contact Sony. 

Or I  can contact them for you to ask a general question. 

BTW, this is a user based community. If you wan an official answer from Sony I recommend to contact them: https://bit.ly/3lns004
