Not heard of this before but I shall look at it.
The picture is quite excellent - what is causing the grey bar at the bottom?

I send things all over the country and I always use Royal Mail Special Delivery. It's insured, it's tracked and if they fail to deliver it by 1pm next day you get your money back - assuming the recipient is there to receive it - which they always are because I ask when they want to receive it before sending and choose the day of the week accordingly to post it. ParcelForce charge twice as much, take twice as long and then you have to pay extra for insurance !!

If you send expensive stuff just "signed for" there is no insurance cover - particularly for GLASS (as in lenses?) so you are quite daft to do so and you are asking for a row with the buyer when it turns up busted or it disappears and he's left with no recompense

Does a nice job that does. One of the things I like about macro is the sheer detail it shows you.

As to my collection of old glass, I plump for the problem of dust. They sit out in the open on the desk top where the air can get round them and I hoover them now and then with the brush attachment. Before they are used they get blasted with a rocket blower

I've got the original Pentax battery and three Energizer clones which I keep in a desk drawer. As one fails it gets charged and the next one comes out of the drawer in strict rotation. I've never had any problem with the clones whatsoever. Being into macro, I use LV a lot but I always cancel it as soon as I'm happy with the result and ready to take the picture. I worry more about the mechanism that's holding the mirror out of the way than the power it's using.

Only one macro lens? I've got six (the Industar is maybe the best of them)

Takumar preset 50mm f4
Pentax A 50mm f2.8 macro
Pentax M 100mm f4 macro
Industar 61 L/Z 50mm f2.8
Cosina AF 100mm f3.5
Amar 105mm f4.5 enlarger lens (arrived from Ukraine today)
and a full set of Pentax bellows
I'm still short of a Volna - anybody got one?

I like the sky in the first one - it's a lovely colour and about the right amount of it

Once you get used to the P30 you will really like it. Let us know how your pictures came out

Chrome has been a complete disaster with Win10. Almost unusable. Thank heaven for Firefox

6 - wonderful foreground

So it's not the result you wanted -- it's a jolly good result whatever you wanted !
