Leaked Fujinon XC 13-33mm F3.5-6.3 – Surprising Specs and the First XC Lens to Truly Tempt Me!

Share

We can now share the main specs of the upcoming Fujinon XC 13-33mm F3.5-6.3 OIS.

And we are going to compare them to the XC 15-45mm F3.5-5.6.

There are a couple of nice surprises: the XC13-33mm is more compact, lighter, yet has a more sophisticated lens design (hence likely a better image quality). It comes with 9 rounded aperture blades instead of 7 (better bokeh?). It also has a more powerful optical image stabilization and a mechanical zoom instead of a powerzoom. I also like that the minimum focus distance is fixed at 20cm through the entire range.

That’s quite a nice set of improvements!

Below you can see the specs comparison.

I guess for many this could be an ideal ultra-portable kit zoom lens for many X-M5, X-E5 and X-T30III or X-T50 owners.

This is actually the first XC lens that has truly caught my interest and I can’t wait to finally see it unveiled on October 23 at 1AM New York time.

If the image quality is good, it could be an ultra compact alternative to my XF10-24mmF4.

I feel like Fujifilm has made lots of correct choices when it comes to developing the XC13-33mmF3.5-6.3.

Don’t forget: we will have a nice live blog only on FujiRumors.com ;).

But just out of curiosity, I will also share the estimated specs that Fujifilm itself mentioned in what some (erroneously) consider the hidden Fujifilm X mount lens roadmap:

  • Affordable Wide Zoom Lens – XC Lineup
    – Size 40-50mm
    – 60-70mm diameter
    – weight 130-170g

We can see that Fujifilm made the final lens even smaller and lighter than they initially estimated.
