Help me rate this lens....

[kds315*]

Have to test a 150mm lens, made a few tests shots unfortunately w/o a fitting sunshade.

How would you rate it?

The image samples look great, I can't see anything to complain about regarding this lens. What lens is it, what camera did you use, and what processing did you apply?

[kuuan]

a bit strange that you Klaus, of all people, would ask this question. But I take the plunge, from what I can tell from these samples I'd say sharpness looks good, bokeh pleasant and colors quite dull

[calvin83]

It seems this lens is single coated. Are you using a 150mm lens or a 6" lens?

[bernhardas]

Like mentioned above the pictures are quite "clear" and the bits in focus at a distance can be even a bit crisp.
The in sharpness focusing at the near end seems not up to the same level like the far end.
Colors appear muted in dull light.

I am not sure I can say much about bokeh from the two examples that have some .
The pictures are also not made to test or push flare?

This lens seems to be from some sort of copying device I guess. I know it is f=150mm and it seems single coated indeed.

I can only use it in some crude setup, as it has a thread I have no adapter for. It is obvious that it is quite sensitive to stray light,
but I have no sunshade for it, so maybe I make one from cardboard, as indeed the contrast is rather low and the colors dull (rainy
day actually today...). Will see if I have a chance to re-shoot by tomorrow, weather permitting.

I have mixed feelings about it, so I wanted some other opinions

Hard to tell my impression is nothing special , but impression is very dependent from subject, I had a few lens in this focal length all was similar like this , even cheapest Tamron 150mm f3.5 zoom sharp, low contrast.

[calvin83]

I think you got the Cooke Copying 6" if you say it is 6".

The photos seems OK to me if they are taken with a hood in a rainy day. The super six series have very low contrast but the Asians pays a large sum for one. As long as the bokeh is nice, it is a lens to keep.

Sunny today and made a (seemingly too short) clamp on sunshade...harsh lunch time sun it was.

That one I especially like... foraging bee on Helianthus tuberosus ("Topinambur")

[drjs]

Hmm. I forgot the words I was looking for. Oh yeah, found it. I think it was "bitingly sharp". A good performer at macro range no doubt.

[kds315*]

Thanks! Here some in late afternoon light...





















Very sharp, but also very sensitive to light situations (compare #3 + #4)
Best for controlled light situations or studio work I'd say...

A great photographer makes any lens look good
What about showing us this mystery lens?

[kds315*]

Thanks Lars!

[Tervueren]

Some really beautiful shots there Klaus, have you posted the photo of the slipped roof tile before as it looks familiar to me.

[kds315*]

Thanks! Yes, many times (as the one with the golden globe in it) as it is one of my "standard targets"

Here one I haven't shown, shot against the blue sky

Beautiful work, Klaus! The flower shots have bold color and pleasant bokeh.
As everyone has already indicated, the lens has excellent sharpness and a contrast and color palette which is largely dependent on shooting conditions. Have you thought of trying this optic for portraits?
