Fotodiox Tough E-Mount

[PaulDalex]

I remember a RFFer complaining about the plastic mount

A solution seems to have come out.

What do you think?

Do you see any con to the substitution? Or only pros?

Cheers

I'd only be concerned about lens-sensor alignment after attaching the new mount. There's not only tolerances to consider, but also screw tightening and mount flatness.

You are quite right, in my opinion.
For heavy lenses a collar with tripod attachment would be a better solution. Not easy to find though
BTW: very nice site

I did not know this problem was a real problem I must admit. I had assumed that the lens mount was all metal. I have two Sony NEX cameras one of which I tend to use with legacy lenses and adapters. Some of those are pretty darn heavy by comparison with any Sony NEX lens (although not perhaps by comparison with a Sony A mount lens on an adapter which Sony seems to have designed the NEX to handle, at least according to its advertising). In any event I would consider getting a new mount for that camera if I am able to get one easily - i.e. without high ebay delivery charges which some sellers charge (not sure about fotodiox).

I adapt Leica R lenses on the A7R, all under 700 grams, using a Novoflex adapter. There's no play perpendicular to the imaging plane, but there's slight rotational play around the adapter, which is irritating for manual focus. I hear that this is due to the connection between the locking pin and the slot in the adapter, so this replacement mount won't really fix it, alas.

If you've used an A7S with its stainless steel mount, then you'd know that it corrects the lateral and rotational play found in the A7 and A7R. It was like night and day for me.

I read another poster's comment about replacing the plastic mount with this one, and he brought up a good point about it being designed to fail. It's easy to replace a mount on the A7. Very difficult to fix a broken lens or camera body. Could be a good point. If you drop your A7S with a heavy lens, you might destroy something important instead of your plastic camera port flange.

I'm more interested in a camera that feels better to handle, but might be too rigidly constructed, than one that has breaking points that affect everyday handling because of their fragility and loose tolerances. I'll probably order a Fotodiox Tough mount if I don't sell my A7R in anticipation of Sony's 2015 offerings.

Thanks. I did own an A7S for a week but didn't pay attention to the rotational play at the time. But now that I think of it, you may be right--so I should probably give this Fotodiox replacement a try.

I tend to use a wrist strap and am not too worried about dropping my camera.

I remain in the Uhm department,
On one hand I cannot find the courage to mount big cannons on the A7R (e.g. I have a Zeiss C/Y 100-300).
On the other hand, as Turtle says, I am wary to compromise optical quallity.
Perhaps I could buy and keep it for a DIY repair just in case (as Samurai says).
BTW now I remember it was Samurai the first to complain about the plastic mount! He was quite right, despite comments to the contrary posted here!
Thanks to all for the smart comments. In no other place there is more competence than in RFF.
