Update: Just received Joshua's Batis 25/2. It's still overcast here but I will try to run a few comparisons today.

So, first off, I tested Joshua's lens for centering and lucky it was well-centered.

About the lenses: Physically, they are equally long and the Batis is a bit lighter (only 40g). The Loxia is much skinnier though. :-)

I had a chance to test them at infinity even though lighting was not perfect. It's a bit flat from a cloudy day.
Still, it's possible to compare resolution and contrast between these two lenses. As I thought, the Loxia has the edge in micro-contrast and resolution. The Batis did very well but for landscapes, I would prefer the Loxia.

Both lenses were manually focused at infinity distance (best of 3 for each one). No other settings expect for "vignetting" correction and "sharpening" for both lenses.

Here are the crops:
PS: The f/2.4 comparison was done with the Batis at f/2.5. Keep in mind that for these first crops at f/2.4, the Loxia was wide-open.

f/2.4 (center)

f/2.4 (mid-zone)

f/2.4 (extreme edge)

Here are they at f/4, which I think it's optimal for both lenses:

And here are they are f/5.6.

At f/8, the Loxia still remains better.

Wow! The Loxia has better fine detail at all three reference points at f/2.4!

I may have to break down and eventually get the Loxia 25, even if it impacts my L21 use somewhat. There may never be a Loxia 28, so I don't want to wait in vain.

Thanks Fred. Looking forward to more under better light and maybe subjects at various distances.

Seems like the L25 and VC 40/12 would be a nice out-and-about pair.

Fred, thank you for the comparison of the Zeiss lenses. Yes, under controlled conditions and for landscape, the Loxia appears to be ahead by a bit. Of course, at f/2 the Batis is faster and it has an excellent close focus capabilities for semi macro usage. What is the minimum focusing distance for the Loxia, Fred?

Great test, Fred. I’d say both lenses did VERY well. I don’t think I would be able to tell a difference unless it was a very large print. Looks like I may be getting a Batis! Just wish it wasn’t so fat...

Joshua - do you find you use the Batis 25 more or less than the FE 28/2?

I believe the Batis is .20m and the Loxia is .25m.

The Loxia 25/2.4 + CV 40/1.2 is quite a pair.

Yes, the Batis has a bit more astigmatism towards the corners and lower resolution at wider apertures. Here are the MTF graphs fro both lenses:

Eric, roughly about the same, depending on my tolerance to the bulk at any given moment. Lately, though I grabbed the Batis a little bit more it seems.

Thanks, Fred! Somehow, it seems to me that the Batis tends to be able to focus close but I don't recall the actual MFD and I never had the Loxia 25mm.

With the Batis, I remember not being a fan of the high LoCA and onion ring bokeh. However I also remember the Batis having very nice smooth OOF rendering.

I will test this against the Loxia as long as Joshua gives me a couple more days.

It's also unnecessary 'fat' just by looking at the elements...

Feel free to do so, Fred! I have a photoshoot coming up but I won't be needing that focal length. Hang on to that lens until next week or so. I will see whether I can swing by at your place. Thanks!

The Batis does gave smooth OOF rendering, but Lox is even better! Im travelling fir rhe next week or Id post the crops...

I got 15 minutes of sun and compared them at many distances. Posting soon.

Let's analyze this image: (Loxia top)

Following at 1:1 crops from it.

Here we can see that the Loxia is sharper with higher micro-contrast at f/2.4 (wide open) than the Batis at f/2 (wide open)
OOF rendering looks slightly smoother and less contrast and less color errors for the Loxia.
