p.9 #1 · Loxia 25mm f/2.4 Distagon Tests and Comparisons


The Laowa 15, Loxia 25 and CV 40 are the best combo I hit since turning to Sony several years ago. Add the Loxia 85 or even the ZM 85 and you have maybe the best MF kit around. Now if there was a 28 worth it saltyou could go 15, loxia 21, 28? , 40. I personally given up on a 28 and like the 15,25,40,85 combo . The one lens that could be intriguing is the Laowa 10-18 coming. But I’m kinda doubting the IQ will be flat out outstanding. But will see

Man 15 to 25 just seems like such a big gap. I was looking forward to trying out 12, 18, 25, 40 but that Laowa 15 is so tempting for astro I'd love to work it in.

15 is can be too wide, 25 might not be wide enough.

p.9 #4 · Loxia 25mm f/2.4 Distagon Tests and Comparisons


Focal lengths preferred are very personal and highly depending what one is shooting. For me the gigantic disappointment that new Loxia was 25mm, not 28mm. This is because 28mm is widest usable lens on most of shooting I do, even then I'm forced to crop 16:9 more often than I wish for. 28mm is also widest focal length, which sky is not totally ruined in 100% of photos when using polarizer (I need polarizer for my foregrounds, not for sky). If I could choose I would prefer slightly long 28mm which would be more 29-30mm in focal length. I really like compositions which 28mm makes possible.

I really like to shoot with 50mm. As perspective of 50mm is very neutral (not wide, neither has tele compression), it's up to photographer to make images to stand out.

Then I need one or two longer lenses to support two previously mentioned. In perfect world I would combine 28-50-100 for majority of shooting, then add 100-300 zoom or 180-250 prime to these.




For me 21mm and 18mm are just "trick"-lenses, which rarely have any actual use. They are are so wide, that in environment I live in, there isn't really big enough hills to use it for any landscape stuff and for rarely there are any boke scenes I want to shoot with this wide lens (they show too much sky etc.) - these are useful in urban shots, but year by year I shoot less urban stuff, last few years mostly just testing new lenses when I don't have the energy to go to nature. What I see in Flickr and forum majority of photos shoot with these really wide lenses just scream wide wide wide, but are contextually and compositionally pretty bad, and would greatly be improved if photographer would have done more exclusion than inclusion - of course there are few exceptions, and when someone nails it with this wide lens photos look exceptional.

There are billion 35mm lenses, multiple fairly good as well in my opinion, but for me this focal length is just bad compromise; it doesn't have wide angle perspective, but it's wide enough to have compositional issues and due to focal length it's subject separation abiltiies are much worse than 50mm lenses.



But as we do not live in perfect world, there is (subjective opinions)
- no good 28mm (except Zeiss Otus and maybe Leica Summilux, both giganticly expensive)
- no really good 50mm either (I would love Leica APO-Summicron-M or Summilux-M ASPH, but I see them too expensive, Zeiss FE 1.4/50 has too modern rendering style with high contrast boke, otherwise seems great lens), to some extend I can replace this with Zeiss G45, but it's "only" f/2 and has hexaconal aperture closed down
- no good and fast 100mm (Zeiss ZE/ZF/Milvus has it's issues, C/Y Sonnar 100 is good but quite slow with f/3.5 maximum aperture and hexacon shape aperture closed down kills it for me)

So I have to settle for 25-xx-85 combo for marority of shooting. On this the xx would be 35mm compromise FOV (leaves "too large" gap to 85mm) or not optimal 50mm (leaves slightly larger than comformatable gap to 25mm). The gaps between focal lengths/field of views are not that important. To solve "xx"-problem I'm considering to get CV 1.2/40, but not really sure about it as the focal length is so close to 35mm, which I find very annoying.

Last summer I shoot in few days using just Contax G-lenses, the combo of 21-28-45-90 felt really good to shoot, but hexaconal aperture shape in G28 and G45 makes them much less useful.



On summer 2018 I really focus to find out can I live with Loxia 25's too wide field of view. Otherwise I'm already sure lens is perfect for me, the boke&transitions are wonderful and focus plane just the way I want it(high contrast, high microcontrast). It's really question do I learn to hide white sky in my forest shots well enough, the wide field of view makes it really difficult. This far it seems much more difficult than with 28mm lenses.

You should add the 40/1.2 Nokton to your kit: Lox25, CV40, Lox85 with superb resolution, contrast where it matters, smooth bokeh rendering and 10–point defined sunstars.

p.9 #7 · Loxia 25mm f/2.4 Distagon Tests and Comparisons


I'm dying to see a head-on comparison vs. the Batis 25 (which I already own).

On the one hand, I think I'm willing to sacrifice a little bit of image quality in exchange for AF and f/2, which I think are both useful at that focal length. On the other hand, I've also got the Loxia 35, 50 and 85, so rounding out my Loxia kit is *super* tempting, especially if the 25 is a noticeable improvement over the Batis.

Probability of CV 1.2/40 ending up to my camera bag is high, it seems best compromise. I really liked the samples someone posted this week (rocks and waves in beach). Unfortunately CV 1.2/40 can't be purchased very easily from Europe at the moment, e.g. Amazon.de or Amazon.co.uk don't even list it, and eBay has just some "smells like fraud" sellers claiming to be from Ireland, but actually located in Hong Kong

What comes to Loxia 25; I'm done testing and from now on just shooting and adapting to slightly too field of view (for me). Came home few minutes ago from photographing and greatly enjoyed shooting with Loxia 25. The short minimum focus distance combined with very high image quality also at MFD makes it possible to get great perspectives. At least as long as light overpowers the sky, not fun at all when it's cloudy. Unfortunately due to climate change or whatever 10+ year "crappy summers" period is going on, ~75% of time Finland seems to have cloudy weather => this wide lens is really difficult as ugly white sky is really difficult to avoid.

Thanks for the tests and comparisons Fred. Looks like the Lox25 is (unsurprisingly) a great performer.

Apologies if you have already answered this somewhere in the thread, but do you feel it's worthwhile having both the 21 and 25 in the kit?

Sorry for the late reply. Currently I own both 21mm and 25mm lenses and although close in focal length, I find the change in AOV noticeable since the 25mm seems to be a slightly narrower than 25mm.

Don't worry about Irish listings by Hong Kong sellers. It's not a scam. I believe it's grey import and since Ireland is in the EU there are no duties or extra taxes to pay. Warranty is provided by the seller but I don't know if Sony et al will touch those lenses at home (probably not). I have bought a couple of lenses from them and everything worked out fine (but no Swedish menus in an RX100IV, no big deal since I actually prefer English). One lens, however, was the wrong mount (A instead of E) and returning it resulted in a full refund and return postage paid promptly. However, I'm not sure I would dare buying something more expensive, like the FE 100-400, from them although the savings would be substantial. BTW, the "Irish" seller had a warehouse located in England.

As for the CV 40 I first decided against it but this forum won me over. Although I'm located in Sweden I ordered from Robert White in the UK in the beginning of March. During Easter they had a 5% discount so I contacted them and had 5% deducted from what I already had paid and in the beginning of April the lens was delivered, a little earlier than our friends in the US had theirs. Recommended seller.

Forgot to share some actual shots in this thread. Generally I have been very happy to lens, but still struggle with "too wide" FOV, but super happy to rendering style. I have not found the "boke CA" to be problem in real world shooting, at least not in my use. If you want to take closer look PM me and I'm happy to share RAWs.



Zeiss Loxia 2.4/25 FE @ f/2.4, 1/320s, ILCE-7RM2 @ ISO 100



Love the way how lens rendered this scene - Zeiss Loxia 2.4/25 FE @ f/2.8, 1/320s, ILCE-7R @ ISO 100 + 125cm/50inch silver reflector



Zeiss Loxia 2.4/25 FE @ f/2.8, 1/400s, ILCE-7R @ ISO 100 + 125cm/50inch silver reflector (or white, not 100% sure anymore, this was many weeks ago...)



Zeiss Loxia 2.4/25 FE @ f/3.5, 1/400s, ILCE-7R @ ISO 100 + maybe used reflector, I'm doubtful as the target is so large that my 125cm/50inch reflector can't light this size subject



So low contrast on boke, loving it! - Zeiss Loxia 2.4/25 FE @ f/4.0, 1/125s, ILCE-7R @ ISO 100 + 125cm/50inch white reflector



Notice low contrast on boke, prevents background to steal the focus - Zeiss Loxia 2.4/25 FE @ f/5.6, 1/160s, ILCE-7R @ ISO 100 + 125cm/50inch white reflector



Same scene as above, but with f/13, and boke remains low contrast!!!! - Zeiss Loxia 2.4/25 FE @ f/13.0, 1/30s, ILCE-7R @ ISO 100 + 125cm/50inch white reflector



Zeiss Loxia 2.4/25 FE @ f/2.8, 1/125s, ILCE-7R @ ISO 100


In rare case I would ever shoot this wide lens closed down, it seems to perform fine as well. Compared to many modern Zeiss lenses, I would say that character&rendering style closed down & large distance of Loxia 25 is similar to old Zeiss lenses like C/Y 2.8/28.


Zeiss Loxia 2.4/25 FE @ f/9.0, 1/50s, ILCE-7R @ ISO 100



Zeiss Loxia 2.4/25 FE @ f/9.0, 1/40s, ILCE-7R @ ISO 100

Great samples showcasing its beautiful rendering Samuli. The Lox 25, CV 40 and Lox 85 are currently my favorite lenses.

The CV 40/1.2 has a different rendering and OOF does not get smoother as we stop it down but I like its character. It's my default lens unless I need go to wider (25) or longer (85).

Yes, a wonderful lens, the Loxia 25. So glad Zeiss made this lens and I could go all Loxia.
The only thing that I reallly do not like, and am a bit disappointed that Zeiss could not do better, is shown in the first image by Samuli: the loCa wide open on the tree, and then the (dark) green fringing in particular. It can get quite thick and rather ugly. In fact, it reminds me of old manual Pentax A lenses that I had and used on digital.
I am a bit surprised that such a modern lens with such high quality rendering fell short in this one area.

Fortunately, there are many shots where it does not occur, and I also aim to use the lens closed down to f5.6 a lot. Still, for the wide portraits at f2.4, it may ruin a few shots.

Where in the 1st image you see it? It was nice old forest (=not the usual one raped by forest industry with low biodiversity) and with all kind of moss and fungus growing on dead and living trees. The tree had gray/green stuff growing on top it's dark brown bark. Is that what you are referring or do you see it some other place than the main tree?

On these images I was bothered by boke CA only when I processed the 2nd image; in center of image bright branches of fallen tree on background boke - luckily boke CA was green and I had green background, and therefore it's hard to see unless you look RAW image @ 100%.

Your tree fooled me then, and the better for it!
Good to know the green fringing only clearly appears when zooming in a lot.
The bokeh on your old forest tree looks very similar to what I got with old film era lenses, but not the lens in this case.

Here though is a crop of the OOF area at f2.4 that does show the lens' green fringing, but honestly: it is a 1250px crop at 100%, so is not even really bothersome until cropping significantly. I dó intend to crop in post with the lens often, but only for composition, and not this much.

edit: I see there is no option to insert an image into the post....

so now with hyperlink...:

ChrisMak, this is crop from TIFF, what I used to create the JPG of second photo of my post above = sharpened etc. not "pure RAW". This was only of those photos, in which I did see boke CA:

So yes, in specific conditions it will show up. For boke winter photography (on countries with snow...) this lens would be horrible.

Yes but that green fringing behind the focus plane helps soften transitions when shooting foliage which translates to smoother rendering. We all wish for less axial color error, but in some cases, too much correction affects bokeh rendering negatively.
I find the Loxia 25/2.4 much better corrected for CA compared to the Batis 25/2.
