If the vignetting is more prominent than the Loxia 21 when stopped down, that would be reason enough for me to stick with the Loxia, as would reduced flare resistance. Sharpness seems not be a delineating factor from what I see in Fred's shots.


At f/2.8, the Loxia shows stronger vignetting (expected)
At f/4, they are pretty equal. (Voigtlander does slightly better)
At f/5.6, they are pretty equal. (Loxia does slightly better)
At f/8, they are equal

As I wrote before, the Loxia's biggest downfall is its moderate inwards field curvature. The Voigtlander is flat-field in comparison.

Here is the same example above focused on center. They are equally sharp at center but the edges look softer for the Loxia due to field curvature. (Even at f/5.6, it does not get completely masked...really needs f/8)

If I would focus on the corners, they would look very similar towards the edges.

Went to the park to play around with the 21, most of these are wide open

First two , i just like the focusing on

A lot of detail wide open, imo

Next three focused on lion head, a lot of detail in the brick

Im mainly testing 1.4-2.8, I already know from 2.8 on focused at infinity is good enough for me for landscapes

It is nice that you can have a wide 21mm that can be versatile and fast enough for more than just landscapes, imo

Fred, any chance to do a flare/suntstar comparison vs the Loxia?

Flare Resistance:

The Loxia seems to have better flare performance (ghosting).

Here is a sequence comparing the CV 21/1.4, Loxia 21/2.8 and 24/1.4 GM:
(All at f/8)





Top: Voigtlander, Mid: Loxia, Bottom: GM (All at f/8)






Top: GM, Mid: Voigtlander, Bottom: Loxia (All at f/8)

So, in my opinion the Loxia performed slightly better here. The Voigtlander is able to maintain great contrast but there is "usually" more ghosting present.

Notice that the Loxia renders a 10-point sunstar, Voigtlander 12-point and the GM 22-point.

I will repeat this with more scenes to be sure this holds true.

The Voigtlander 21/1.4's distortion is very similar to the Loxia with a simple and easy to correct barrel distortion. The Loxia has slightly more distortion,
To test, I used Lightroom's vignetting correction from the Loxia on the Voigtlander and the latter got a bit over-corrected.

Here's a sample:




Original (Voigtlander top)






Corrected (Voigtlander top and perhaps a bit overcorrected)...The Loxia 21/2.8's Lightroom vignetting correction used for both lenses

It is nice that you can have a wide 21mm

That's a beautiful scene for testing Longitudinal CA (LoCA). Thank you!

Seems to go away by f/2.8.

2. Perceived build quality:

The Voigtlander's choice of metal and finishes simply feels like a special, higher quality product. The Loxias are a bit muted, a bit ordinary, by comparison.


I have to disagree.
I appreciate and like the build quality of modern CV lenses, but I don't share your feeling about Loxias being muted or ordinary by comparison. At all.

Thanks i wanted to show the CA, and yes at 2.8 this lens seems to do everything right, close or infinity imo... wide or stopped down!

Thanks Fred! Hmmm... I was ready to put the Loxia on the B&S board but this comparison may have changed my mind. I saw a bit of ring flare from both the CV and the GM in the second set too.

Not sure what your definition of "moderately sized" is but the Lawoa 15mm F2 is an excellent lens.


The Laowa's size is fine with me .However, I have evaluated it quite extensively (4 copies) and I find at 42mp it doesn't reach the corner IQ I want (both sharpness at wider apertures and coma) . So for now at least I carry the Sigma 14/1.8 despite its size, but would love to see something smaller in the future if it can get close to the Sigma's performance. I'm not sure we can ever expect a Loxia 15 at 2.8, but maybe CV is the alternative.

Thanks Fred. This looks good. As with sharpness (excluding FC) not enough difference to delineate. between the two.

Thanks again Fred. Definitely agreed. This looks clearly in favor of the Loxia, as I was probably expecting from that lens' amazing flare resistance.

So the decision to make in terms of IQ (for landscape at least) appears to be mainly whether you want flatter field curvature, or better flare resistance. Since photographing against the light is a common occurrence and high priority for me, I will be sticking with the Loxia.

I'm still looking forward to your coma results, but astro for me is usually a matter of 18mm or wider so won't factor into my decision between Loxia and CV 21.

p.s. The much lauded GM does quite poorly in this comparison, and has a poorly defined sunstar too. For landscapes at least, the Loxia 25 which is also sharper remains a much better choice imo.

IMO, the 12-point sunstars the new CV21 has look even nicer than the 10-point ones the Loxias and other CVs have.

Normally I am not that into wide lenses, but this one is a lot of fun.

Iím the opposite, I prefer the Loxia sun stars, thatís whatís so great about choices!
