Sunday Morning Lens Quiz #04

[ItsReallyDarren]

We had 28mm before, then 50mm, now 35mm this Sunday!

One modern 35mm lens, one classic 35mm lens.

Details will be revealed when the poll closes in three days.

[Lens B] [Leica Summaron 35/2.8] shot at 2.8

Hmmm lets see, the background is more out of focus and there's more shadow detail in the photo taken with lens A.

Not that tells me much...

But I'll guess that the lower contrast of the vintage lens helps to retain more shadow detail, so my vote goes to A as the vintage lens and B as the modern lens.

Up: Classic
Down: Modern

 

[Erik van Straten]

Lens A is the modern lens. The out of focus backgroud in picture B becomes sharper towards the corner. That is typical for old lenses. This phenomenon is called "curvature of field".

Erik.

A Classic
B Modern

Re Erik's comment, I thought field curvature was a function of design and lens speed, not period of manufacture. Interesting.

I'm guessing A as the classic and B as the modern. Reason is that a lot of modern 35's have focus shift, and if you focused with an RF camera on the tree, then the focus shift is focusing a bit behind the tree in B.

This goes to show, that a proper lens test requires a NEX to factor out focus shift.

A looks like the 35/1.4 Nokton to me.

 

[crawdiddy]

A=Vintage
B=Modern

...based on higher contrast on B, and sharper OOF areas.

 

[Moriturii]

and sharper OOF areas.

I keep hearing this, wish people would stop saying that, it's a complete oxymoron. Sharp bokeh? What? Cold fire? huh? A blunt edge that is sharp, que?

 

[redisburning]

based on the OP's signature line, I'm guess that A is the modern lens and B is the vintage lens; because I'm paranoid.

 

[fotomeow]

well..... if we go by the "typical" attributes of older vs modern lenses, being contrast and sharpness, then I would choose A as the vintage and B as the modern. But, Erik V.S. has a rep for knowing his lenses, and he has chosen the opposite.

And Ferider's choice is interesting. If A is the CV/1.4, it would have to be a SC version, no?

I can't think of any modern lenses with lower contrast: Certainly not Leica or Zeiss. Maybe CV? Maybe a Russian copy?

 

[Nomad Z]

I go with A being the modern lens, because it appears to have been shot at a wider aperture than B, yet has less vignetting in the corners.

It certainly could be. But just to play "devil's advocate", we dont know the camera used, the medium used, or the f value, which could affect vignetting.

3 days is way too long to play this game.

3 days is way too long to play this game.

Its surprisingly suspenseful, no? I guess 3 days gives more opportunity for participation. But the # of voters is only at 32, with 443 views, thats less than 10%.

 

[ferider]

Here is the histogram of the two pictures .... Just saying

 

[ItsReallyDarren]

3 days does sound a bit too long to keep people waiting. I've asked the moderators if they can shorten the poll time to end on the 1st. I'll reveal the answers tomorrow.


In the mean time, I leave you with Lens A and B at F/8.


[Lens A]

[Lens B]

 

[ampguy]

that's weird. A looks wider, but shorter than B.

It's a comparative, and thus not at ali illogical: a blunt razor blade can be sharper than than an axe.
