I just put in my rental order to Lensrentals.com for the Sony LA-EA5 A-mount to E-mount adapter and the Sony A7R IVA camera. I’ve been wanting to find out if using this adapter on the A7 cameras that are “allowed” to autofocus motorless A-mount lenses would be a valuable option for me or not. I have two very high-quality A-mount lenses that currently can only be autofocused using the LA-EA4 adapter. This adapter uses a translucent mirror that contains some rudimentary auto-focus points rather than the much more capable sensor based autofocus capability of the modern Sony mirrorless cameras.
This rental will allow me to test this new adapter to see if these old lenses can be returned to reasonable and productive use. If they do perform satisfactorily, I’ll still have to purchase one of the cameras that have this capability with motorless A-mount lenses. Currently only the A7R IV and the super expensive A1 have this capability for full frame shooters. Neither are what I’d want to shoot. But if the upcoming A7 IV camera will be given this capability then I’ll trade up my A7 III and get the LA-EA5 for the sake of using these old lenses.
The two lenses that I am primarily interested in using are the:
Both are extremely sharp optics that produce images I like.
