A7r zoom magnification issue

[njwhitworth1978]

Hello,

I'm new to this forum and am having an issue with manual focus and my A7R.  I've set C1 up with 0x - 7.2x - 14.4x zoom magnification but when I activate this sand zoom in to either 7.2x or 14.4x the magnification zoom only last for about 1 sec before reverting back to the 0x view.  This obviously doesn't give me enough time to accurately MF.  Does anyone have experience with this issue or know how to ensure that the zoomed in view is maintained until I have focussed and decide to exit the zoomed in view?

 

I'm running f/w 1.20 and metabones EF to E (mark IV) adapter with f/w 0.41.

 

Thanks in advance.

Hi, 

 

can I assume you already set the menu voice for choosing focus magnification time to "No limit" (2nd menu, 1st page, 3rd voice from the top)?

 

If that's the case, then you might be experiencing a bad case of "contacts flu". It happened to me with a couple of chipped adapters when I used legacy lenses on a Canon 5D Mark II (using focus magnification in Live View).

 

Basically the contacts of the adapter and the ones on the camera are not properly aligned, or they just move ever so slightly when you handle the lens or something like that, and so the camera "reverts" to its normal state (i.e. no magnification). If I'm right you should probably contact Metabones for a repair or a replacement under warranty (assuming it is not expired).

 

To be absolutely sure you might try to magnify the focus using a "dumb" (i.e. without contacts) adapter; if the problem persists you have a faulty A7r, if it goes away then the culprit is the Metabones.

HI addicted2light,

 

Thanks for your reply.  My A7R was recently repaired and all settings were restored to defaults - I hadn't noticed that the focus magnification time was set to 2 secs.

 

Thanks for your help,
