Subject: [Leica] 135 APO Telyt-M flare and spots on images
From: Simon Lamb <simon@sclamb.com>

I just developed a roll of Delta 100 that I shot using my new (used) 135 Apo
Telyt-M.  I noticed two anomalies in the negs that I scanned which I hope
someone here might be able to explain.  The images are entirely
uninteresting as I just wanted to see what the lens could do.

The first image is of a wheel on a car:

Inside the wheel arch on the left hand side there is a round light spot that
was not in the wheel arch when I took the picture.  The spot is on the
negative.  Here is a second shot taken about ten seconds after the first
using the same lens:

Even though the image is darker the round light spot is not on the negative
or on the scanned image.

This second shot is of a bay tree,  As you can see, there is a light area on
the tree, looking like flare.  It is on the negative but it was definitely
not on the tree when I took the picture.

Also, at the bottom of the tree on the right hand side there is a round
white spot.  The area just below it was a child's soft toy that was lying on
the grass, but there was nothing on the grass where the white spot has
appeared on the negative.

All the pictures were taken on a bright (not sunny) day with a full cover of
cloud, so the light was even and diffused.  The lens shade was extended for
all shots.  All other images on the roll using this lens were fine with no
spots or flare.

Can anyone explain the flare on the tree and the spots inside the wheel arch
and just below the right side of the tree?

If the lens is at fault than I can return it.

Thanks.

Simon
