I really like wild flowers.... I wonder how they cut
the grass

I see a BIG RED Advert for PENTAX on the bottom of
all Steven's posts

Of course you would.... you've got very severe LBA

That doesn't stop the cookies though
I get Facebook and Twitter cookies and I never go
on either and have Noscript blocking their scripts.

I also have a load of sites blocked in the HOSTS file.

I even have a cookie called accounts.google.com
What's that about Are they going to start charging
me

Sometimes I wish I had a computer of my own

Firefox under Tools/Options Privacy has a tick box marked

Seems to be off by default...... there's been an uproar
from advertisers over MS turning it ON by default on
the next IE (possibly Windows 8 ).

The only problem I see with the new uploader is that
you can't delete the pic afterwards.

That's a funny pic Don

That's the same... when you remove the inner ring off the
T2 it has an outside diam of 49mm and a grove diam of
46.5mm so the grubscrews project 1.25mm into the grove.

The focal length is adjusted as per the Wikipedia link above:

"Because the T-mount has a long flange distance of 55 mm
and most 35 mm cameras have shorter flange distances,
a simple mechanical adapter called T/T2-Ring is needed
to adapt a T-mount lens to any camera body without
optical correction to achieve infinity focus."

For the extension tube I mentioned above the T2 outer
ring goes over the K mount which has a barrel diam.
of 44.5mm so the screws have to stick out 2.25mm....
they are about 5mm long. The 49mm hole has to clear
the 3 No. 1.5mm projecting lugs on the K bayonet which
it does by 1.5mm

Some Russian lenses have M42 T Mounts and I have swapped
mine over to T2 K Mounts i.e. Jupiter 11A 135mm f/3.5

Your computer belongs to Google!

Just do some mid grey shots of a white wall/card at different
apertures and see where it becomes acceptable. It's normal
will most lenses.

This is something like what you will get:

Grey_Exp_Test_M-35mm_f2-8




Note: Vignetting returns at f/16 and f/22 something no one
ever mentions

I'm not a fan of HDR, but this isn't too bad... hardly
noticeable.
