I'm glad to hear from you guys.

before I paid for it, I read that the Leica Q lens is about the best in the world.

Since I paid for it, I am sure about that.

Years ago (more than ten), there used to be some real differences in lens quality and rendering approach from one manufacturer to the next.  As automation has improved (both in terms of assembly and the grinding of surfaces), multi coatings have improved, and molded aspheric lenses have become ubiquitous he differences have eroded.  Now you see more of a difference between price points within a brand than you tend to see across different brands.  Basically, you almost can’t buy a “bad” lens these days.  There are still subtle differences in rendering or in approach to lens design, but the vast majority of lenses made today would have been considered exceptional by the standards of fifteen or twenty years ago. 

Lens designers still need to balance cost, optical performance, and weight/bulk, but most manufacturers now make a range of lenses so you can find something that matches your priorities fro Leica, Panasonic, Fuji, Nikon, or Canon.

That being said, the lens on the Q/Q2 is particularly good.  The field is flat, and it is sharp to the corners by f/4.  It’s pretty good even wide open, especially in the middle of the field. There’s a little lateral chromatic aberration but not much, and it is easily corrected in post. The lens is also quite compact for what it is.  How is this accomplished?  Primarily by applying software correction for vignetting and distortion.  That’s the current trend with most manufacturers these days since it is generally very effective and Leica doesn’t need to worry about someone using a Q lens on a different camera body that may not be able to profile the lens.  It’s permanently attached.

Leica makes excellent lenses.  These days, so do most manufacturers.

Thanks you Jared for this.

The lens on the Q is made specifically for the Q and its sensor, it's effectively a combined unit. It also relies on digital correction for optical distortion - you wouldn't want to use the lens without it, images would be badly distorted, but of course it's intended and part of the optical/digital combined design for this type of camera to result in an overall excellent end result.
