Same set-up as before, but with the 100macro replaced with a SMC M 50mm f1.7 reversed.

1 minute @ f11.

Yes, I noticed that, Doug, & it's done it again! I did turn the image up the other way in Elements 11, it was held in the clothes-peg upside-down when I took it!
I think, for some reason, it's the same as on that edition of QI on the telly....
with a vacuum-formed model of Einstein's face . When revolved, it looked the same in positive relief as negative...

Weird!


Thanks for the tip re green button, I'll try it next time.

Not very nice outside this afternoon, so here's my go at it!

K5.

Pentax Auto Bellows M, 150mm ext.

Kenko P/AF 2x tele converter MC7.

Extension tubes, 65mm.

100mm D FA Macro (Sorry....)


Focused in live view, using the focus stage of the bellows set.

Unable to stop down from f2.8 because of the bellows, lack of connectivity. (Any ideas, anybody.....?)


(No image of set-up I'm afraid, my Optio S5i has given up the ghost!)

The optics in the A version are the same as those in the M mark II, which is not the one shown at the start of this thread. The optics in the original M version are not as good.
How can you tell what one's what, from external appearances?

Some images from a walk near here in Wiltshire, today.

There's a small winterbourne that has gone down considerably since its peak during the recent floods.

These all shot over a small bridge, where the water babbles over waterweed & stones, with dappled sunlight playing on the surface.

Tried first to take the weeds & stones themselves but found that the sunlight was spoiling the view under the surface & the sunlight reflections were playing havoc with the metering.

Decided to focus, instead, on the ripples themselves, stopped right down to f22, which gave a much slower shutter speed.

And look what happened!

Was out with mine today, set the Custom, Option 28, "Degrease lens" to "1" for on and the difference was miraculous, almost as if I had upgraded to the MkII and removed the AA filter.[/quote]Precisely the sort of upgrade I was looking for.........!

I don't have any of the new kit to which the Pentax site refers, I was just wondering if there was anything buried in there that would improve the general performance of my K5........

Could someone please let me know what differences I could see by updating my K5 from version 13, which it is on now, to the latest version 16?
(My most used lenses are the Sigma 150-500 & the D AF Macro 100.)

Thanks,

Roger.
