Rainy weekend : guess the 35mm challenge

[Stef63]

No scientific lens testing, just for fun, I mounted four 35 mm (with adapters where needed) on the SL2.  All at f2.0. Can you guess which lens is which? Or which letter corresponds with the numbered picture.

A : Sigma 35 mm DG DN Art f1.2

B : Leica 35 mm Summilux-M f1.4

C : Leica 35 mm Summicron-M f2.0 v4

D : Canon 35 mm EF-L f1.4

Interesting, I love these kind of practical tests.

Is the ruler the focus point?

Yes.  The 6 and 7 was my target focus point. I manually focused the Sigma and the Canon.  The field curvature surprised me, and also the fact that 35 mm is not always 35 mm.

Maybe I should add "pick your favourite" to the challenge 😀

[Alberti]

My suggestion is:

C (35-Cron, the rather good book / corners and I’d say the warm tone; the dia blades still visible wide open. . . 
B (35-Lux, overall quality, but soft edges, warm tone); does it have a steel rim?

D (Canon EF, overall lack of quality, just my aversion )

A (Sigma, everything is ‘right’ - but cool)

I started by eliminating the Sigma from the list. Then the Canon. 🤭

[dpitt]

Hard for me because I do not know the Canon and Sigma, but I like the challenge:
35 cron
35 lux
35 Sigma
35 Canon

this is what I meant as list . . 

1 =  C (35-Cron)
2 = B (35-Lux) 
3= D (Canon EF) 

4 = A (Sigma)

Close..  ☺️

I need to clarify that lens B is the Summilux- M FLE.  Maybe this helps, or not.  😇

This helps a lot, or rather, I was already puzzled how good your Summilux 35  I or II had to be!
Now it turns out you meant the Summilux-M 1:1.4/35 FLE ASPH. That is a different race altogether.

My guess is now

1. 35 lux
2. 35 cron
3. 35 Canon
4. 35 Sigma

[Alberti]

Having a FLE in the game I expect that the last one was definitely FLE.

So . . swap around

1 = C (35-Cron)

2 = A (Sigma)

3= D (Canon EF)

4 = B (35-Lux)

[Stef63]

@AlbertiNice try, but now only one is correct.  😕

[dpitt]

@Alberti And am I getting closer ? 🙂

@dpitt : We have a winner !

It is indeed the lux, cron, canon and sigma

Thanks. I identified the first two as Leica because of the 3D rendering. There was some confusion about which version of the 35 lux was involved at first...
And I do not know the Canon and Sigma.
Clarification about the FLE made sense.

I was always good at mastermind, so you partially gave it away with this. Combined with the fact (i hoped) that the first 2 had to be Leica.

PS: differences were smaller than I thought. There is not a bad one amongst the 4. To me the Sigma is the least pleasing by a small margin. Maybe the test image was somewhat limited to really stress the optics.

Great excercise. 

The FLE 'should' be better.

That is, I have a 45mm DG DN myself (not as complex for sure but with a certain clean signature and bokeh) and it can be excellent in many pictures. 

[Stef63]

Here you see of course the Sigma at f2.0.  The real purpose of this lens is wide open at f1.2 where it shows a pleasing bokeh.  But I agree that the Leica lenses demonstrate their quality compared to other brands (even in not so challenging conditions)

A surprise to me is the lack of sharpness of the Canon (even stopped down).  I used this lens a lot 20 years ago and considered it always as an excellent sharp lens.  Haven't used it since 2009 when I stepped into Leica.  Now I have the Sigma MC-21 adapter and must conclude that there is a significant difference between Canon (even their L lenses) and Leica glass.  (but more on that later when I post another rainy day "mastermind" challenge.)
