Bad move! Looks like they want to sell off Pentax

Ha! Ha! Is that the best Ferrari can do?
Plastic bag over their light fitting
They should get Pentax to make a waterproof one

I like them all.... 1st Class as usual

All cameras are quite useless at focusing accurately see....

Live view is about the most accurate way. but it's
better to focus bracket or at least repeat the shot
a few times.

Most of the Pentax AF problems (apart from tracking) should have been
fixed with the K-5ii f/2.8 sensor, but you need lenses of f/2.8
and below for it to work.

I'd like to see if the Green Hex/Beep MF is any better, but
don't fancy buying a K-5ii just to see if it is.

I like the sketch effect in No: 1 and the frame in No: 3

I've not had any problems with the latest 150-500mm on a
K-5 even with a Jessops (clone/type) 1.7x TC.

Just as an example this is one of the most consistent lenses I've
got for exposure in Av mode from f/5.6 to f/22..... It's an M42 CCTV
lens, but doesn't have a stopdown pin so it just stops down as you
turn the aperture ring. Similar to, but not a pre-set.

Mainly due to vignetting it needs 2/3 correction at f/2.8 and
about 1/2 stop at f/4..... Spot on f/5.6 to f/22 which is
unusual f/22 usually falls off.

Shots of mid-grey Expodisc. Custom north sky WB set in camera (K-5).
Should read about 117R 117G 117B




If it were an A Series lens it would be 2/3 stop out
on every stop due to open aperture metering.

Most lenses are poor wide open and can vignette a few stops as
well. It's a miracle that they manage to get a reading that
is anywhere near the correct one. The old stop down metering
of cameras like the Spotmatic made a lot more sense.

I don't know if Pentax have a database of corrections that they
apply for each lens. They should do I can't see how it works
otherwise.

I wouldn't buy a Car that colour clashed with my Kettle!

Well done Honesty

I was thinking the other day that now this thread is at
1044 +/- It wouldn't be a bad idea if we had someone who
could count beyond that for Health and Safety reasons

Can you calculate the circumference of a cows hoof!

You might have to do a bit of Googling for this one.
I think this thread link covers it, but the pics are missing.
It seems to be around Pin 7 on the lens that you need to
sand.
