My tele prime lenses:

Tamron SP 90mm F2.5
Tair 11A 135mm F2.8
Vivitar 135mm F2.8
Meyer-Optik Görlitz Orestor 135mm F2.8 (fungus)


Can you guess which picture was taken with which lens? Razz

It's difficult for me because of those lenses, I only have the Tair, so I will try to guess it.
I'd like to know if you used a constant aperture between the lenses, if there's some taken wide open. I have an idea about the Tair but it's a lens (like many Russian portrait lenses) which changes character from wide open to stopped down so I would like to know what I should look for.

Also I would like to know if you applied any sharpening to the images.

No post processing, only exposure automatically corrected and pictures resized by raw converter.


I can't remember apertures, but I think all except second pic are wide open. These pics were not shot in the same day, lighting may have been a little different. Maybe this is too difficult.

Well, I was going to make a guess about difference in colours (although if you used AWB that would be meaningless, too), but if they were taken in different days, the whole "castle" tumbles down. Blind tests are fun but to mean something and not only a fun, they should compare images made in the same lighting condition.

Really second pic not wide open? And third wide open?

OK, I will try anyway.
I try:

Tair-11A = first image (been long undecided with #4 to tell the truth)
Meyer Orestor = second image.

I have no clues to tell the other two lenses apart. The only thing I am fairly sure of is that pic #3, if it's really wide open, can not be the Tair.

That's correct. You have a good eye Smile

Third is Tamron, last is Vivitar...

Thanks. I know Smile
I rarely miss a blind test, when I know the lenses!
On this forum, two blind tests made, and two won. Smile

I think I am the living proof that there ARE differences between lenses, and that a trained eye can pick them.

BTW I was going to try Tamron as pic#3 too, based on the bokeh of the 28mm lens that I have, but then I decided that it would have been to go too far.

Tamron has quite ugly bokeh but I think it's the sharpest!

Yes it was the sharpness that gave away the Tamron (the only one I got right Embarassed )

Here full resolution versions:

Tair
Meyer
Tamron
Vivitar


None of them is very sharp here, these were just quick shots wide open (i think), dark weather and I'm still no good in focusing.

I think Tair and Vivitar have better colors than Tamron and Meyer...
