Sigma Mount Conversion Service turns Your Sony E Mount DC DN into Fujifilm X Mount Lens

Sigma is creating quite some buzz right now with the official announcement of their first X mount lenses and the teaser of more goodness to come in future.

What some might not know, is that Sigma also offers a “mount conversion service”.So, if you already own any of these lenses for other mounts and now would like them for your new Fuji X system, you can get them converted directly by Sigma.

Available Mount Conversion Service

This service converts the mount of SIGMA lenses to that of a different camera body, allowing photographers to continue using their favorite lenses over the long term regardless of camera system.

Note 1: The Mount Conversion Service is different from a normal repair. In order to apply for the service, please contact your nearest authorized SIGMA subsidiary or distributor. https://www.sigma-global.com/en/world-network/
Note 2: This service is performed exclusively by SIGMA.

Sigma X Mount Lenses Coming February 21: Low Profile Announcement with No Sigma Stage Online Event?

So, it’s out: according to information we have received, Sigma will announce its first autofocus X mount lenses on February 21.

Now, over the last few years, Sigma has launched new products at the so called “Sigma Stage Online” events. And some FR-readers made me notice that Sigma has not yet announced any Sigma event for February 21. As a consequence, some doubt that the rumor is correct.

Look, I am called FujiRumors, not FujiFacts, so there is always a possibility that I am wrong.

With that said, maybe the lack of “Sigma Stage Online” event does not mean necessarily that nothing is coming at all.

Maybe Sigma just decided to go more low profile with this announcement: a sober press release that announces the new X mount Sigma trinity and that’s it. That could explain why (at least until now) no Sigma Stage Online event has been announced.

One question I get often these days is: will Sigma make some design changes over the current versions (hence adding an aperture ring)?

Look, at this point in time, I have no answers to this questions. If I am able to get one, I will answer it on FujiRumors, otherwise I am afraid we will have to wait for February 21 to find out for sure.

Certainly Sigma had enough time to make design changes and put an aperture ring on them. But rationally speaking I believe for Sigma it is simply more convenient to keep the current design (hence no aperture ring). So while I hope in an aperture ring, I am not very optimistic about it. But maybe Sigma did put some effort into changing the design, knowing that Fuji X shooters generally love aperture rings on the lenses. Let’s hope so.

Sorry, guys, I am late.

But I’ve received this information right while I was cooking my wife’s favorite dish for a Valentines Day dinner (*quick instructions below).

Anyway, now we are done, my little Fuji lover is going to bed with his mom, and I have time to share it with you.

The rumor is this one: Sigma will launch its first X mount lenses on February 21.

We also confirm that the lenses to be announced will be:

Linguine/Spaghetti with shrimp and rocket salad (Rucola) and lemon and tomato

Time to prepare: 15/20 minutes – 2 people

Put the pasta… and let it cook while you prepare the sauce.

Sauce: Fry a bit of garlic and chili for a few minutes (low heat, don’t let the garlic turn brown). Then throw in some nice, fat shrimps (raise the heat). Let them fry 1 or 2 minutes with the garlic. Then put in a bit of decent white wine (about half a wine glass). Cook for 1/2 more minutes with rather hot flame. Then put in some tomato cut in smaller pieces (should be very mature tomato). Let it all cook for a few more minutes at medium heat (4/5minutes).

Drain the spaghetti/linguine and throw them in the sauce (keep a bit of cooking water in a glass, so if the sauce turns to dry, you can use the cooking water to make it more creamy). Then add the juice of half a lemon (for 200/250g of pasta), the skin of half a lemon and the rocket salad to taste (simply ripped in smaller pieces with your hands) and mix it all nicely.

Now you can serve the dish… and if you do so, feel free to send me the images via email at fujirumor@gmail.com. ;)

Sigma DC DN vs Fujinon XF Size Comparison

As we told you a few weeks ago, Sigma will announce X mount lenses “soon”. I never gave a date (and hence I never said they would be announced today, Feb.9), but I confirm everything I said so far, hence that they will come “soon” and that Sigma will start their X mount adventure with these three lenses:

Assuming that Sigma will not design completely new lenses, but use the current design and just adapt the mount to make it fit on X series cameras, I have made a couple of comparisons already.

One spec that is maybe better seen on images rather than expressed in numbers, is the size of the lenses.

So I used the camerasize.com database to compare the future Sigma X mount lenses to their Fujifilm X mount counterparts.

Note that I’ve mounted the Sigma lenses on a Sony A6600 and the Fujinon lenses on an X-Pro3, since that way both lenses have their mount pretty much perfectly aligned. And of course, camerasize has the Sigma lenses with lens hood, but it’s really not a massive effort of imagination to “think away” those lens hoods.
