Sigma 100-400mm f5.0-6.3 DG DN OS Contemporary Coming for Fujifilm X Mount (New Source)


I know, I know.

In the Sigma world, DG lenses are for Full Frame, whereas DC lenses are for APS-C.

Got it.

But I also got a rumor from a new source (via the revived anonymous rumor box), that Sigma will launch a X series version of their Sigma 100-400mm f5.0-6.3 DG DN OS Contemporary.

The release should happen still this year.

Yes, it’s a full frame lens, but it is not a new practice to adapt Full Frame glass to APS-C, as we can see for example with the Tamron 150-500mm f/5-6.7, which was also initially launched for Full Frame but then Tamron released it also for X mount.

So, if the rumor is accurate, Sigma would just do the same.

Look, I also prefer it when lenses are specifically designed for APS-C, as it would make the lens smaller, but I also get it that for Sigma, Tamron & Co it is simply very cost efficient to take an existing FF lens and swap the mount to make it fit for APS-C.

Again… this rumor comes from a new source. So, while we are grateful for the tip, we also have to take it with the mandatory grain of salt. I was not able to double confirm or multiple check it.
