p.1 #1Sigma 24-35 F2/ Sigma 35 1.4 Plus many comparison lens tests
I thought since I just got the Sigma 24-35 F2 and Sigma 35 1.4 Art series lenses( Canon Mount) that I would run my normal initial tests on them just to see how they compare and make sure there are no issues with performance. So let me say right out front I do this test on every lens I BUY so I have a catalog that is pretty extensive going back several years to even when I shot Medium Format. Its the same test , pretty much the same framing and pretty much always in the early morning. So one may ask what this does for me. Well its a test I can always repeat and look at other lenses I buy to compare against to see what I maybe after. Disclaimer I get paid by no one , i have no dog in any fight over brands and no one pays me to do these and more important no one lends me anything so I have no affiliation with anyone and absolutely no bias. I have been doing this for decades and I get paid by clients that want my services and pay my fees. Thats it ( WELL I DO TEACH WORKSHOPS TO YOU FOLKS)
. Anyway as I normally do these test individually and I thought to myself what if i went back and tried to catalog the whole series of tests i have done with a bunch of lenses. The one issue is they are done on different days and even months but it is always the same test so do count that variability in as it is a variable to testing as it would not be possible to shoot all of this glass the same day.
Reason I bought these two Sigmas is the new Sigma MC-11 adapter promises to offer full AF functionality on my A7rII. So in effect these lenses will be native with that adapter. Now these tests are done on a Metabones Version IV T until the sigma adapter is in my hands. I will test that as well but only for AF functionality it should have zero effect on optical performance.
As I show the 24-35 F2 i pitted a few lenses against it to show how they compare. I used a Loxia 21mm at the same framing as the zoom at 24mm for instance. Be aware I consider the Loxia 21mm to be the new GOLD standard in the industry for super wides. This lens is amazingly fantastic. I apologize right out front your looking at wall images but at least its interesting to look at.
I will add other images as well but if your bored looking at them , change the channel its that simple.
So lets show the Loxia 21 and the Sigma 24-35 at 24mm with same framing. I did shoot these at the same time frame. Just FYI there is no correction available yet for the Loxia 21mm but its very clean in regards to distortion. Something to consider
24-35 at 24mm same framing
Need to ignore the color on the Batis 25mm it was shot last August and the light was pretty ugly. I also missed the light fixtures but on the corner upper left tests we will still see a section to compare. Coming up upper left corner tests. FYI I had to pull the Batis 25mm off the GetDPI servers since i can't find the raws and so the center crops are missing but I do have the corners.
NO BATIS 25 AT F8
As you can see how amazing the Loxia 21 is followed fairly closely by the Batis 25. Now considering the Sigma 24-25 is a zoom its really pulling its weight good here at 5.6 looks very good at 24mm which i consider maybe the weakest focal length in this zoom. Yes it has more distortion than the primes but thats a easy fix. We also need to remember what this Sigma is up against these are two of the finest prime wide angles around. I actually consider the Loxia 21 the best i have seen and folks coming from me thats a big compliment.
Lets take a look at the center crops. I did not go past F4 and my belief is if a lens can't get sharp by 2 or 3 stops down in the center , I really want no part of that lens and will not buy it PERIOD. The Batis 25 is not part of this section
As you can see how good the Loxia is wide open at 2.8 just as impressive is the Sigma zoom at 24mm matches it by 2.8 which is one stop down. Typical for a zoom at one stop down on center
More impressive is the Sigma at 28mm. Coming up next

Sony 28mm F2 versus the Sigma 24-35 F2 at 28mm. These are shot maybe 2 months apart
Upper corners
I did not do F8 but the Sony at F8 just gets there ing the corners. This is why i sold the Sony I found the corners not very good overall. I like this stuff to happen at 5.6 for the corners.
Lets do the center crops
On center they are both very good wide open but I think the Sigma has the edge here at 28mm focal length. Price difference 450 compared to 1000 retail but you get 24 and 35mm focal length and 35mm looks very good against the Sigma 35 1.4 and the Sony 35 FE 1.4. Those tests are next

p.1 #3Sigma 24-35 F2/ Sigma 35 1.4 Plus many comparison lens tests
Lets move on to the 35mm setting which for me is what i am after the most. I have tried almost everything here and here i have the Sony FE 35 1.4 which this test was shot a couple months ago on the best copy I had and I have been through 4 of them. Than we have the 24-35 F2 Sigma and the Sigma 35 1.4. Now the Sony 1.4 and the Sigma 1.4 fall more in the category of falloff going into the corners and have more field curvature than the Sigma 24-35 zoom so you need to decide here if these 1.4 lenses are best for landscape because they really are best for people and the falloff. The zoom is more flat field and the corners are very good compared to 1.4 glass but on center as we will see the 1.4 glass will be sharper on center. Really have to decide what you are really after here. Not in the test is the Loxia 35mm F2 and the Tamron 35mm SP 1.8 and the tamron i can tell you right now will blow everyones doors off in the corners at 2.8 its killer but the lens is designed for that and does not have the look of these lenses tested here. Ill post this test now but will come back with comparable images of other subjects so you can see more of the character , bokeh, bokeh balls and onion rings. Im just flat out of time to get into that right now and again its a lot of work this took me about 7 hours at this point and I have some paying client work. One needs to eat but this test is not over just on hold.

Lets look at the center copies . The Sony 35mm was a touch further back.
Well thats it for now. Ill post this and than i will add other images for comparison. I can't see now.

p.1 #5Sigma 24-35 F2/ Sigma 35 1.4 Plus many comparison lens tests
I will give some opinions on what i think at a later point but one thing is for sure if you can handle the weight and size just at 28mm alone beats that sony 28. This is a interesting zoom as it really has only one weak spot at 24mm it has some distortion but Im seeing nothing else but goodness to this lens. The bokeh is not something to write home about but I am not seeing onion rings either at least for now. Im not sure it would replace folks 35 1.4 glass as it is a different type of lens more flat field but I will say this it maybe one of the best mid zooms around. Now I have not tried the latest Nikon and Canon versions of there 24-70's but this is about the same size and weight pretty much and we don't know about the GM 24-70 but I will tell you this its damn good and it punches above its price for sure. Now Im picky as hell and i like it a lot and its not expensive either like the Canon/Nikon and GMs so it maybe right up some ones alley here at 800 I paid. Of course you need a adapter and I'm waiting on the Sigma and this thing will be full NATIVE AF lens. Same with the Sigma 35 1.4 and I'm really liking that lens even over the Sony 1.4 its sharp , it has a decent look and Im not seeing onion rings yet. I do wish my test on the Sony 35 1.4 matched a little better and I still have my files from the Tamron 35 1.8 and the Loxia 35mm F2 as well. Looking at this test my pocket is starting to hurt. Lot of money back and forth to find a decent 35mm has left me a little cold folks. I just have to be honest about that as going through 4 Sony 35mm really got under my skin. But thats life and we move on, at least thats my attitude as i have been doing this so long and seen so many pitfalls with so many systems . Ill be back to check in and hopefully this really does help someone making these lens purchases. Doing these test helps me figure things out even though there the most boring thing on the planet.

Nice work, thanks for your efforts. It looks like you had a bad copy of the FE 35 1.4, I have it and definetly is a lot better than the pics you show.
In the other hand, now looks like the Loxias will be my next purchase after the GM 85

So, the "ZM" is the Sigma 24-35/2 zoom? On your 35mm test, you wanted to call it "S35" but I think you referred the crops as ZM 35mm...
If that is the case, the Sigma 24-35/2 looks excellent at 35mm starting at f/2.8-4 (center and corner).
The zoom seems to beat the Sigma 35/1.4 prime at the edges at most apertures.
At 24mm and 28mm it's very good starting at f/4-5.6. It's really a great performance for a zoom probably because of its smaller FL range.
I agree with your observation regarding the Loxia 21/2.8. The best ultra wide I've ever had. I thought you would like this lens.
The FE 35/1.4 looks to have low contrast/resolution at the edges and the FE 28/2 does not look good on your samples. My copy looks sharper at f/5.6 at infinity but it's definitely not in the same league as Loxia 21mm .
So, what did you learn from it? What are you keeping/selling?

Maybe I missed the descriptions. ZM 35 on the A7rII? Is that right or is that the Loxia?
Also, the "S35" Sigma Zoom seemed to be missing in the 35 category - or was that mislabeled the "ZM" above?
Edit. Fred beat me to it!

Yes ZM is the Zoom. I change from S at 35 setting to ZM because the other Sigma was introduced at 35. I labeled one S than changed to ZM after I crashed. I was killing my machine . Lol

These are awesome tests Guy, thanks for the effort. I just got the 24-35mm myself. My testing on the 5DSr matches what you're seeing. At 24mm the edges take quite a while to sharpen up and only reach excellent quality at f/8. It sharpens up much faster at 35mm.

Fred all your points are right on the money at 24 and 28 it looks really good and at 35 beats the other two in the corners much sooner in aperture. A very good flat field zoom it appears. Yea I'm not thrilled how the Ze 35 looks here it was shot at a different time and different light. The last test together was the Lodia 21, zoom and the Sigma 35 1.4 so these are very accurate in all phases. It's tough to shoot these at different times as you can see, so I would just use it as a data point on the FE 35 1.4. The 28 I had was the best of two, I was not happy to have to get to F8 in the corners. In case no one sees it the Sigma 35 1.4 is sharper on center than the 24-35 at F2 the zoom needs to almost get to 2.8. Pretty normal for a zoom to have to get one stop down although it's still very good at F2. I'm being critical here but that's kind of what we are after. In many ways the zoom kind of takes the 1.4 place except for bokeh and fall off. But if you need corners at F 4 the zoom will and the 1.4 won't come close. Really kind of tough to decide for sure.

Guy thanks for the tests. The Sigma 24-35 really looks great for a zoom. The Loxia 21 is such a special lens and it shines through in your tests. I enjoy mine a lot. I preordered the Sony 24-70 GM and will be looking forward to seeing how that performs. Thanks again for all the work you put in on this!

Yea I kind of hit it at 5.6 and I was expecting F8 . Maybe different sensors stuff? Not sure but seems I have a great copy. Have you noticed the distortion at 24mm, that's about the only thing I see on the negative side. I'm not seeing CA yet
It's a very nice lens and the costs is excellent for it. The penalty is your carrying a big mid zoom. Now I would never take the Sigma 1.4 and the zoom at the same time. So you get a penalty of one big lens in the bag. I can deal with that. I'm really impressed of the 28mm setting. Having the Loxia 21 and 50 this fits smack in the middle

Thanks Chuck and I may at some point get the GM instead but this certainly will hold me for awhile and I can save 1400 for right now, what I'll do is rent it , test it against this Sigma and see what we get. My priority is the GM 85 first

It's probably the difference in resolution - the 5DSr is incredibly unforgiving at the edges. Some of Canon's current best lenses have trouble there as well. The distortion is pretty wavy on my brick wall test. I bought the Sigma 20mm f/1.4 as well and that design seems to have some very strange midfield softness; haven't taken the time to look at it more closely.

I bought the Sigma 20mm f/1.4 as well and that design seems to have some very strange midfield softness; haven't taken the time to look at it more closely.

Yes regarding the Loxia 21 I am dead serious it's about the best performing wide I ever bolted on a camera outside my MF tech cam lenses but that's a different world and a extremely costly one those lenses for the same focal length cost 8 grand. What really amazes me is even wide open the corners are good right out of the gate at F 4 it's clean across the whole frame.

Yea I kind of hit it at 5.6 and I was expecting F8 . Maybe different sensors stuff? Not sure but seems I have a great copy. Have you noticed the distortion at 24mm, that's about the only thing I see on the negative side. I'm not seeing CA yet
It's a very nice lens and the costs is excellent for it. The penalty is your carrying a big mid zoom. Now I would never take the Sigma 1.4 and the zoom at the same time. So you get a penalty of one big lens in the bag. I can deal with that. I'm really impressed of the 28mm setting. Having the Loxia 21 and 50 this fits smack in the middleIt's probably the difference in resolution - the 5DSr is incredibly unforgiving at the edges.

Interesting for sure. Having the Loxia 21 I passed on the 20 1.4. I'm excited for this adapter coming if we get all the AF and BTW this is a absolute pleasure to manually focus than this will be a important lens in the kit

These are awesome tests Guy, thanks for the effort. I just got the 24-35mm myself. My testing on the 5DSr matches what you're seeing. At 24mm the edges take quite a while to sharpen up and only reach excellent quality at f/8. It sharpens up much faster at 35mm.It's a very nice lens and the costs is excellent for it.

Not sure anyone noticed also the Sigmas color looks very close to the Loxia Zeiss glass. That makes life easy
