A dot screen printed cardboard box is excellent for focus
testing. Interference with the dots causes them to appear
as diagonal lines when exactly in focus. I use this mostly
to check MF lenses. I also run a piece of black elecrician's
tape accross the box for AF. (Not shown here but I have a
piece vertical as well. I also leave it somewhere to
get dusty, because I can manual focus on the dust in LV.
This only works at certain distances usually about 1M.




A ruler clamped to an old piece of wood and plonked on top
of the box at 45deg with the 2" mark in line with the face
of the box gives an approx. indication of how far focus is
out. With some lenses there will be a colour change from
magenta to green at the focus point.




Does £100 in Kit Form sound reasonable

Equipment used: K-5 + Pentax_A 50mm f/2.8 Macro at f/2.8

Ebac list a drainage kit for the bigger models, but drainage
that's not up to building reg. standards can cause a lot more
trouble than just moisture in the air. 21 L/day onto the floor
can do a lot of damage. A floor gully would be the ideal
solution and might not be such a bad idea in the dining
room

Human being utilizing technolodgy!

zzzzzzzzz!!!!!!!

Vincent the Vandal and his pals will always hang around in
well lit areas rather then areas that are badly lit

This tutorial as good as it is is only HALF complete!
What did you bake with the flour afterwards?

That man looks like my baker

It's in the manual. You set what type of AF to use
in LV.

You can also focus accurately in LV using Manual Focus.

Just a rip off. A cardboard box with a ruler at 45deg
at the bottom is just as good, but the method I pointed
to in the other thread is a lot easier and more accurate.

Gorgeous! ...... Don't look anything like our
slag heaps..... can't even see any coal dust!

Just looked on Ebac's site. It seems most of these can extract
up to 21 L a day but only have a 3.5 L tank, so it's going
to stop after 6 hours anyway

All the energy used is given off as heat plus heat is given
off by the water condensing on the coil. So you probably get
back twice as much heat for the enrgy put in. Would it not
be better therefore to run it mostly during the day when the
heat is usefull.

Just noticed that Soran has now said the RH has dropped to
60 this week so it looks like everything id OK now and the
de-humidifier won't be needed for more than a few hours a
day. I wouldn't even bother with it at 60.

Hadn't seen that before. Very clear view of what was in
his darkroom

How did he manage without Fast AF

Did he ever move over to a Full Frame Camera
