  1. Yes
Has anybody had any connection issues with their 200-600? I attached mine to my A1 last week and the aperture just displayed as -- and the lens also failed to focus. The camera was also incredibly slow to turn on and off. I also tried it on my A7RV and had exactly the same problem. My A1 is also working fine with my other lenses so I can't see it being a camera issue. I've cleaned the contacts but the problem remains. I read over on the DPReview forums that someone had a similar issue and it was diagnosed as: "ZMR Assembly-Faulty F-stop". I've never needed to send a lens in for repair before so it will be interesting to see how that works and how much it costs!
 
I think that these companies should have to give a fully detailed report of what was replaced and why, with evidence that the did too. That's a big bill
 
Proofs in the pudding as they say ,let us know when you have tried it out . I recently came back from holiday and only took the 70-200 f2.8 with my old trusty A9II no problems ,but on my return used the 200-600mm for some barn owl shots and it just wouldn't focus properly. Jiggling the lens on the body made no difference . Came back home checked all the usual nothing to spot . Did factory reset went out again next day it was like a new lens . The only thing I did notice was that I had left Bluetooth and remote switched on but can't imagine this would make any difference .
 
So my 200-600 is now back with me. Well it actually arrived a couple of weeks ago just before I went off on holiday but I didn't have the chance to try it out. So it took just under 4 weeks from when I sent it off to Fixation. The total bill including shipping it back to me was £679.33 😭 Did they need to replace all of the parts that they said needed replacing? Apparently, although I have no way of knowing if that's the truth or not. Still, it was cheaper than a new lens although I probably wouldn't of replaced it since I'm very happy with the Sigma 500. But I may sell it at some point and hopefully I'll get a bit more for it than I paid to have it fixed.
I know of a site where you can sell it Tim 🤣

This is due to this lens having a history of the 5th lens group becoming faulty,

This bugs me. If it has a history of becoming faulty, then Sony should pay for it!
 
yes now and then mine is a very early copy and I have never updated it, but it has always worked fine after turned off and on again
 
I'm sure you have already, but I'd take a pencil eraser or isopropyl alcohol to the contacts on the lens, and check that it turns all the way to locking into place.

I haven't had any trouble with the 200-600, but I don't use it a huge amount (it's on the edge of "too long / too heavy" for me).

I've not tried an eraser yet just a lens wipe, will see if I can find one! It's locking into place just fine.

Isopropyl alcohol and cotton swabs. Lens wipes won't cut. I'd to the erase and follow with the alcohol to clean up any residue.

I've done that now but it's still not working 😭
 
Another question: Did you try a different camera, and if not, did you try a factory reset?
Yep. Tried my A7RV, A6700 and A7IV. Same problem.
 
Sorry to hear that. Hope it isn't too expensive to fix.

Me too! I need to contact a few places and get a rough idea of what I’m looking at. Still, hopefully the Sigma 500 should arrive next week so I’m not in a big rush to get it sorted as I don’t see it getting too much use once the Sigma arrives.
 
has this got the same problem as yours?


Thanks for sharing these Andrew. Yep, basically the same or very similar problem to mine. Mine also has quite a bit of play and always has done. Just about to contact a Sony service centre to see what they say.
 
When submitting an online repair request with Fixation they gave me an average cost of £82.36 - £352.14 for repairs to the 200-600. With the lower end being for minor issues and cleaning and the higher end when components need replacing.

They arranged the collection and it's being collected next week. Now I just need to find the lens cap which I recently lost and the original box which I fear I might have binned after a clean out when moving house! 😭

Do you still have the soft case? That’s more important than the box - can always pack in soft case then bubble wrap and a suitable box.

Yes this happens to me. For an instant fix semi-remove the lens and attach, you don't need to fully remove the lens. For more of a fix make sure all the screws are tight on the lens connection point, this tends to be the issue most often. This also will occur more often when I forget to switch the strap from the camera to the lens.

Tried this but no joy. The screws are tight but they were coming a bit loose a while back so it’s definitely worth checking them now and again.

I should do somewhere, I don't normally bin the cases. It will definitely be well packed. I don't want to pay for replacement glass as well.

had the same yesterday ... in my case because of wearing the heavy lense often over the body of my A1 ... it was needed to tighten the screews of the mounting plate on the cam side

Glad it was an easy fix for you! Unfortunately my screws are tight and I’ve tried it on 4 different cameras, all have the same issue. This might help someone though so thanks for sharing!
