Can you tell? Noctilux vs Noctilux vs Nokton

[redsky]

Purely for fun. Noctilux f/0.95, Noctilux f/1, Nokton f/1.1
No editing other than cropping it to 5x7.
Same shutter speed, same white balance.

Well, 50% of us voted one way, 50% of us voted the other, we will soon see which of us is right, or if we are both wrong.

 

[BLKRCAT]

I voted but looking again I would vote, F1, F0.95, F1.1

 

[Erik van Straten]

I voted: f/1.1 f/0.95 f/1.0

Erik.

 

[Emile de Leon]

F1/f.95/F1.1

 

[Rob-F]

I voted but looking again I would vote, F1, F0.95, F1.1

Yep, that is what I chose, as well--based mostly on DOF.

 

[rfaspen]

Hmmm. I voted same as Erik. I did base my "guess" on the DoF areas and the amount of apparent coma, etc.

 

[icebear]

My guess : 1 / 1.1 / 0.95

 

[anerjee]

I voted: f/1.1 f/0.95 f/1.0

Erik.

Same for me. I own none of the lens, but the natural vignetting is a consistent feature in all CV lens.

 

[aizan]

the .95 is noticeable, but the other two are a toss up.

 

[benmacphoto]

I voted f0.95, f1.0, f1.1, but second guessing myself now haha.
Very hard to tell, but I am now leaning to f1.0, f0.95, f1.1.

 

[Erik van Straten]

Now I tend to f/1.0 f/0.95 f/1.1.

Sure is that the second is the f/0.95.

Erik.

 

[Keith]

f1.1 ~ f0.95 ~ f1.0

If the shutter speed was constant it really can be no other way judging by the levels of exposure in the darker areas of the tree.

 

[tightsqueez]

You can spot the 0.95 from a mile a way... worst bokeh I EVER seen on the edges (last 1/3) of any lens. I know this only because I owned one for five years. Do not miss that lens one bit. Junk.

 

[redsky]

Forgot to mention, but of course they are wide open and focused on the exact same point using LV with high magnification.

I found interesting how f/0.95 seems at first to produce a much shallower DoF than the other two, but I guess it's much more about the rendering of the out-of-focus areas than the size of the DoF itself.

This is interesting, I will give you guys the answer later on. For now a small clue: the solution is in the coma.

f1.1 ~ f0.95 ~ f1.0

If the shutter speed was constant it really can be no other way judging by the levels of exposure in the darker areas of the tree.

That assumes the T/Stop is the same as the f/stop for them.

 

[kxl]

f1.1 -- f0.95 -- f1.0

 

[ferider]

Now I tend to f/1.0 f/0.95 f/1.1.

Sure is that the second is the f/0.95.

Erik.

Me too.

Keith, it's tricky because the 1.0 Noctilux vignettes like crazy. We'll see I guess.

 

[Erik van Straten]

This is with the f/1.1 at full aperture. Maybe this helps.

Erik.

 

[maddoc]

1.0 - 0.95 - 1.1
