IIIf and hektor 28mm

[bobkatz]

Friends...this is my first portra 160nc with my IIIf and hektor 28mm at 6.3. the lens is some foggy, and scratched. I saw some vigneting, is this characteristic for this lens? , do you think the lens worth a CLA?, the photo has no manipulation at all, just downsized por post it. Regards...

Erwin Puts says :
vigneting is 3 stops, but distorsion is not visible at all.
Medium contrast at the (modest ) maximum aperture with good reproduction of the subject outlines and pleasing central definition of finer details. The zones next to the center are quite soft, but improve when approaching the corners.
This behavior indicates the balancing of residual errors to optimise the performance.
Stopping down does improve the overall quality and best aperture is f/11.
A CLA should be a good decision.

JC_braconi...thanks very much for your time and opinion...I will read E.Puts...Saludos...

Bob -

It's difficult to say since this appears to need a better scan. I improved it some, but without a better scan limitations of the lens will be masked. Perhaps John Mead, a master scanner will see this and comment.

Have you a filter mounted?

That amount of vignetting might be caused by using the wrong filter or lens hood.

Agree with JC... old Hektor wide open DOES vignette significantly, can't help... boys, it's a design of '30s... and color films were yet to come... and the only competitor was a Zeiss Tessar f8... I have the Hektor and also the postwar Summaron 28 f 5,6: I used this one many times with film, and was really better than Hektor... but anyway, better to close also it at f11
Of course, with M8 part of the vignetting problem is solved...

Thanks all of you friends...Michael, no filter mounted. anyway Im trying my second portra 400, at f/25, half exposed 1/200 sec, the rest at 1/500...and this lens came with all the kit I got http://www.l-camera-forum.com/leica-forum/film-forum/66118-finally-my-new-leica-iiif.html
I know I will have a lot of fun friends ¡¡¡

If you want to shoot colour film with a 28mm on an LTM Leica, buy a Skopar.

However, you do get a unique look by using these older lenses with colour film - don't expect modern performance, and vignetting is quite normal.

From the first shot I would say that your lens has some haze, which will benefit from a CLA.

Will Leica ever listen and make some LTM mount lenses again?!

Thanks Earley...I will enjoy these oldie lenses ¡¡¡ with all their pros and cons...Saludos.
