(Update) Use of Pentax mount SIGMA interchangeable lenses when attached to the “Pentax K-1”

Thank you for purchasing and using our products.

We would like to inform you of our policy on the repair service that we announced on May 11th,
regarding the use of Pentax mount SIGMA interchangeable lenses when attached to the “Pentax K-1”.

For customers using our interchangeable lenses with aforementioned camera body,
we apologize for the inconvenience.
Please find the following details for the phenomenon and products;

【Phenomenon】
When some SIGMA interchangeable lenses for Pentax mount are attached to the PENTAX K-1,
the upper part of the mount can be scratched.
※This phenomenon is due to the interference with the shape of the upper part of the mount on the PENTAX K-1
camera body and it does not occur to any cameras other than PENTAX K-1.

【In case of scratch on the PENTAX K-1 camera body】
In case your PENTAX K-1 camera body has got a scratch from attaching aforementioned lenses,
we are planning to repair the damaged part of camera body, too.
The detail of repair will be announced later, and we would probably ask customers to send the camera body and lens to us.

* Once we receive the camera body, we would ask RICOH IMAGING or its authorized repair stores to repair it.

We will inform the lead time for repair, and return the body and lens as quick as possible.

We appreciate your continued support for our company and products.

I can see this line scaring away 99% of US customers...

This should put to rest the argument about who is responsible for the incompatibility.

This should put to rest the argument about who is responsible for the incompatibility.

I'm not sure about that. But it at least puts to rest the argument about which company has better customer service, and wants to keep their customers happy.

Pentax could learn something here. The way they handled, or rather, they way they *didn't handle* the rampant SDM failures was appalling. There's no doubt about who was responsible there, but they never uttered a word of apology or took ownership of the problem, instead letting their loyal customers absorb the cost of premature failures.

This kind of thing right here is one of the reasons why Sigma is my favorite lens company.

I really don't see what all the hoohaa is about. My sigma 70-200 (or 150-500, cant say which) put a small 3mm scratch on my K-1, which looks like a smaller version of the deliberate rebate Pentax engineered into the housing about 3mm above it. From all I've read this seems typical.

I didn't even notice it until I read some of these threads. It is far less 'damage' than a camera of the K-1's class is designed to withstand, and one of the first signs of use/badges of honour it will receive in a long career. This is a chipped fingernail in the schema of camera injuries.

I appreciate their openness and responsiveness, but one wonders whether Sigma would have been better off just letting it go. If that's the extent of the "damage", then it wouldn't even be worth the time and hassle for me to bother shipping my lenses in for the modification.

[wizofoz]

Trust me Edgar, it isn't

[Edgar_in_Indy]

Trust me Edgar, it isn't

Good to know!

[Winder]

No. Its not worth the trouble of shipping.

[Caat]

I suspect Sigma took the view that it was legally safer to address the problem when they became aware of it, rather than pretend it didn't exist. From a certain viewpoint I think that they should be commended for their openness.

Well, if your k-1 got scratched before you found out about the warning, I can see how it would be an emotional bummer for sure. I would hate it, personally.


It's not a gold plated collectable LX, but hey, it's your $$$ spent, and we do like good re-sale values.


Looking at the repair and shipping option would scare me even more than living with it. If it were me, I guess I would learn to live with the scratch and tell myself that the fist scratch was someone else's fault, and now I can enjoy using it without worrying about putting the next scratch on it... and at least it's in an unobtrusive place.


I wonder if it self-clearance's once it's scratched, or if pressure remains and it's not truly gapped? If it transfers any additional down force on the lens mount, in addition to gravity... hmmmm... that wouldn't be good...that would make getting the repair an easier call for me.

Sigma says they send your K-1 to Ricoh as part of the repair... Sigma wouldn't need the lens too if Ricoh was putting back an upgraded part... so I guess Ricoh is just replacing with the same original style part?

If so... I think if it were me, I would ask Sigma for an option B... send them only the lens, and keep my K-1 with scratch.


Still waiting on second wave of US stock... so right now I can't even lament a scratch.

I think that's one thing we can all be grateful for!

[FantasticMrFox]

This should put to rest the argument about who is responsible for the incompatibility.

No. If you learn one thing in customer service it is that the customer is always right. Even if they are wrong, they are still right. Because it doesn't matter if you are right or not, if you don't help out the customer will always go home and bitch about it to everyone they know, which hurts you in the long term.

So this service is not necessarily an admission of guilt.

[Erictator]

Edgar,


Unlike the over-used LOL on the net, I actually did laugh out loud at your post.
Thanks, I needed that.

Of course. Ricoh wouldn't redesign part of their camera for a non-conforming 3rd-party product...

Anyway, it's nice to see Sigma properly addressing this issue. Now, if they'd only make a compact wide, I might consider getting my first Sigma lens...
