Guess which lens this is :)

Thanks, I see it now. Interesting...
Lack of contrst could be due to: flat sky and the use of the Neutral picturestyle.
I'll shoot again under more sunny conditions.

I also noticed it in the dog hair. If you look carefully you will see it has lots of detail...but it kinda looks low contrast or as if you reduced clarity in lightroom. the 35L I use to have lost some contrast wide open. If you shot a textured white surface at F1.4 and then F2.0 both were sharp in the center, but the F2.0 one showed much higher contrast.

Well you do have alot of distance between the subject and BG and the exif is not intact so what exact aperture did you use wide open for this capture to give us a little more hint ?

I can get blurring like this with my CY 85/f2.8 Sonnar at f2.8

Give us a HINT !

HINT: my lens is shorter than 85 mm
Correct guesses so far: older lens, manual focus.

Very well observed!

Close One or more of these attributes is correct.

Aah, I wish.... the DOF would be even thinner then.

Hmn....Nikon 50mm f/1.8

nikkor 50/1.2? nice game we have here.

Well The CY 50/f1.4 or CY 50/f1.7 both have a more nervous blurring effect then this so could it be the Rokkor 58/f1.2 ?

Nikkor 55mm f/2.8

Bingo!

I revived my old Nikkor lens.
It is about 25 years old and I finally bought myself a Nikkor/EOS converter with focus confirmation chip.
The only drawback is the halo, which usually occurs around purple colours as far as I can tell.
Out of focus hotspots (like sun reflecting on metal) have very strong purple haloes as well.
When i stop down the aperture they disappear.

So far I'm very pleased with the bokeh and the sharpness wide open.
I think that the sharpness wide open is superior to all my other lenses except the 60 mm macro.
It might be on par with my 100-400 wide open.

Focussing works extremely well with the confirmation chip.
Seems to be spot on 90% of the time which is pretty good considering the 1.8 aperture.
And considering the 7D centre spot is a 2.8 AF spot.

Thanks! Great to hear you are enjoying this

We should do more guessing games here

1/3rd a stop actually..

Im shocked i was right

Funny enough i was playing with one of these yesterday on a D7000....Forgot what these old lenses are like to use! (though the copy i had was horribly loose in the focusing ring)

Old lenses really are fun. But for now I am having more fun with the Helios lenses than my nikkors. Next on my list to try would be Medium format lenses.
