Having some trouble with metabones EF-E smart adapter V0.49 firmware on A7S2 using Canon lenses. Wondering if the latest Sony 3.10 firmware messes up some comparability.

Anyone have the Metabones V0.48 firmware by chance?

wow not even 1 comment... Its amazing to think no one is having an issue with firmware V0.49

Anyway, finally Metabones got back in touch with me and sent the older V0.48 firmware to downgrade. Everything is working properly again.

Steve, much as I love these forums i'm finding fewer people using them and thesedays i use facebook groups for a quicker response to any questions

I was beginning to wonder, thanks for the tip Peter!

Steve, it probably helps if you gave actual info. What do you think people are supposed to do with something so vague as "having trouble"? What kind of response do you think people can give to that? You don't even list the lenses on top of not explicitly stating what "trouble" means in your context.

Hah! Gary, I wouldn't of expected anything less.

It's ok though... My original post did have specific lenses and more information. I edited it to be shorter to see if I could make it simpler when we found out it was every canon lens we tried. Sigma's were fine.

I didn't think I needed to be specific. The fact is, If anyone here upgraded to Firmware V0.49 on the Metabones EF-E adapter(A7S2) and used ANY Canon lenses they are all unusable(unless you don't touch aperture or try to focus).

When I typed my question, I was thinking someone would have known, it didn't matter what particular canon lens they used.

Anyway... Metabones sent the V0.48 to downgrade and everything is working properly again. In fact they emailed back yesterday to say they were working on a new version.

Thank you for letting me know how it should have been done, I will try better next time.

Then you should change your thinking.

Hey, there's some detail already! Why did you upgrade to FW 0.49? Did you have a EF Extender? A Contax N Vario-Sonnar lens? Or perhaps the Tamron 45mm f/1.8? Because if you didn't, I don't see why you installed new firmware.

When I typed my question, I was thinking someone would have known, it didn't matter what particular canon lens they used.

Do you know what "assuming" does? Maybe next time you'll try to assume less? Especially for people who have an adapter and don't upgrade willy-nilly like this.

Hey! No need to be a pompous A-hole...

I gave the specifics of the firmware, camera model, adapter type and brand of lenses "having trouble" in the very first post, that never changed. WTF is your problem??? Who gives a damn why the adapters were upgraded?!?

Do me and everyone a favor and don't reply with your idiotic holier than thou BS.

Who gives a damn who you are. To me your just a cocky know it all who loves the sarcasm. By the way, you wont get another response again when you post more ignorant BS.

Why would you change your post at all? What kind of judgement call is that, besides a very poor one.

Hi Steve, thanks for posting. I'll wait on v0.49 as there seem to be issues. I just got a A7S2 as well and this is good information. The OCD in me likes to make sure everything is current (for better or worse!). However, this time I'll wait. Good to hear Metabones is working on a fix.
