Ooo.. A fast lens with a funky FL for mft. I will always be interested in that.

A Sigma trio of 16, 30 and 56 would make for a nice setup. I just wish the 16 was reconfigured for mft to be a little smaller.

I'm just happy it isn't another 42-45mm lens!

112mm equivalent is a bit odd on m4/3, and Sony (and Fuji) already has some pretty excellent options at 50-55mm. So you may end up with not as much demand in either system. If Sigma wanted to jump into a niche, I think 67mm would have perfect here. That's 100mm on APS-C and 135mm on m4/3. Both classic lengths and on two systems with one lens design.

That said, I think I will be very interested in this lens depending on the size. I find 75mm f1.8 to be too long too often. And 42-45mm can feel a bit too close and redundant to my 25mm.

You're saying that an APS-C 56mm f/1.4 lens will be physically smaller than a m43 43mm f/1.7 lens?
No, the opposite.

This is my biggest issue with these Sigma APS-C f1.4 lenses. They are just physically really, really big compared to M4/3 options. Which is obvious, because not only do they cover a slightly bigger image circle, but Sigma is all about low priced, highly corrected lenses, which means they're always going to be really big within that set of design constraints.

In any case, by looking at the proportions of the lens mount, the new Sigma 56mm/1.4 looks about the same size as the 30mm/1.4, so even if without the hood is it a very significant physical size increase compared to the 40-45mm M4/3 lenses in the same budget category.

Compact Camera Meter

Probably it is about the exact same size as the 42.5/1.2 Nocticron, and just a tiny bit smaller than the Oly 45/1.2 PRO. I'm sure it will look like good value compared to those lenses, but will feel quite similar to handle, assuming you can manage the change in FOV.

The 60mm 2.8 from sigma is very nice. This is brighter

So, this lens mounted on my GX80 will be equivalent to 112mm at what aperture? Price, OIS? Instead of an Olympus 75mm perhaps?

It’s an f/1.4 in terms of exposure, 2.8 in terms of 35mm DoF. Your camera already has IBIS so not real certain why OIS matters. Price will more than likely be less than $500 based on the other Sigma f/1.4 lenses.

This lens, if performance is great, is about perfect for me anyways. I can get rid of my 42.5 Panasonic Sigma 60mm and my lust for the 75mm or Noct with this one lens, further minimizing my kit and picking up speed along the way.

This could replace my O45/1.8 AND S60/2.8, all in one lens. I bet it won't be as cheap as the S60/2.8, but that might not matter if I sold 2 lenses.

Who am I kidding - I've never, ever, sold any gear. :-(

Yeah, that seems...not accurate. How was that image created?

Scaling by existing lens mounts seems to show a somewhat different picture:
