The adjustment done via DEBUG using PK_Tether is cumulative and
100 on the DEBUG scale = 10 on the normal scale.

All my lenses seem to be 0 to -10 and beyond with some
old MF lenses so I might permanently set -100 in DEBUG

It was the 55-300mm lens Dave bought from me not the filter

I can't imagine a UV or similar filter being a problem.
A Polarizer loses a lot of light so hardly any f/5.6+ lenses
are going to be happy with it.

A Tiffen Haze-1 should cut through any haze.

The FA 50mm f/1.4 is probably at it's sharpest at f/5.6.
It does drop off a bit at f/8 and beyond. It's not as sharp
as say the A 50mm f/1.7 It does usually transmit slightly
more light.

The DA 18-55mm is an excellent lens I don't know why people
think it should be poor. It's probably even better than you
pics show, because it looks to be focused on the left eye.

The 1st two pics show the K-5 having the edge over the
K200D probably down to the resolution of the sensors.

Ricehigh has a good method for adjusting the focus:

I'm not some people are because of the removal of the AA sensor.
The K-5 probably only has a weak AA sensor anyway. It's compacts
that have and need a strong AA filter.

I usually MF so faster AF isn't a high priority although I
would like to see more accurate focus indication.

Looking at the 100ISO K5 v K5II-s shots at pixel level the
K5II-s looks better all over, but on reducing the size to
my normal screen width of 1280W there's nothing in it

Even magnifying the 1280W file 4x I can't see any difference,
so upgrading from a K-5 to a K5II-s just to view prints on
screen is not worthwhile. The money would be better spent on
a better viewing program

Worth fixing. The normal problem seems to be wobbly
barrels, which is what stops me buying another.

I used to love the bokeh off that lens.

Here's another from the same set. SR still 28mm
300mm (420mm due to TC)
400ISO 1/250th at f/8 (f/11 with TC)

No PP just reduced from the original JPG
Not sharpened.

Speedboat clubhouse taken from the other side of the
dam. Lens rested on metal fence.




I've also used the Pentax_A 2x-s TC with this lens,
there is some loss but acceptable if you need 600mm

Is that where all the Roughyed's go

This one in Nelson (Best Newcomer 2011 in the Seafish National
Fish and Chip Awards). make a point on the menu that they
use vegetable oil

I'm not sure what Seniors up in Thornton (2012 Independent
Takeaway Fish & Chip Shop of the Year) use, never been there,
but they buy in ready cut chips so I suppose they use
hi-tech fats.

Works well with the Pentax_A 1.4x-s but you have to manual focus,
which is easy at 420mm.

I don't notice any image degradation.

These were handheld at 420mm and 1/250th sec with SR set by
mistake to 28mm




This was against the light so not very good and I haven't
tried to improve it with PP




There's a guy on the US Forum who has got good results with a
Canon screw into the filter ring TC.
