I was particularly taken with the golden flower - but then, I like flowers

I just grabbed the camera in time for the last egg to be laid (hence the poor shot).

and, as if an omen for the future, "dinner" came along to inspect the result!

10 days later, there were distinct signs of things happening

and after 17 days, this scrum erupted, with tiny larvae scrambling to eat everything left in the egg sacs

They scattered remarkably quickly onto the surrounding rose stems where there was no shortage of food (there is a second one barely visible on the very tip)

and began to eat everything that wasn't quick enough to escape

At the end of June they were fully grown and had moved onto the cherry tree - none chose to pupate on the rose stems or the arbour which, by now, were heavily patrolled by ants who were cultivating the aphids

And the first surprise was their ferocity - this one was nipping my wrist in annoyance at having been disturbed - it could clearly be felt as it did so!

Pupating entailed anchoring the tail and violently condensing the entire body backwards and tucking the head underneath.

It took around four hours to effect a dramatic change


Then the second surprise - the little perishers are cannibals! Not good to pupate first!

When they emerge, after about 10 days, their wing cases lack colour and they can't quite figure out how to control or pack those enormous wings

They get there, eventually

and all that remains is a husk

1st is the Panagor (K fitting) with an M42 Zeiss Tessar 50mm on the front followed by 2nd, Pentax SMC M 100mm macro. There are four pairs, all at f8; K5 set at 400asa and Av; all hand held and all untouched JPGs from the camera RAW data (bar resizing).
There is a fifth Panagor shot (since it goes to 1:1 and the 100mm only does 1:2). I have paired this with the same image post processed in Faststone Viewer just to show that it DOES produce good images, whatever others might say of it! OK, so it's not fantastic but I only spent a couple of seconds doing it.
About 1:10


About 1:5


About 1:3


About 1:2


and a camera RAW (.jpg) with the same image PP at 1:1 from the Panagor/ Zeiss combination


The prime clearly produces the better image, even in its unprocessed state but given all the intervening glass, the Panagor puts on a fair show. The selective focussing between the two is interesting as well.
So, that's your "cheapo" Panagor Auto Macro Converter for you.
Oh, and I nearly forgot - on the K5, and upwards I presume, you have to set the very last custom menu item to permit use of lenses with aperture rings.

Did you look at the Russian piece about 'safe selfies'? You on that scooter fits the bill a treat

Firstly, you need to realise that it won't work with your flashy, modern lenses. It works great (on Av) with most old manual ones. Then you have the "problem" of ignoring that lens, having set it at infinity. It's only any use for fine tuning if you are on a tripod. The next thing to sort out is just what is happening with the macro bit. The range is so vast - 1:1 through 1:10 it is easy to think something has gone wrong when you can't see a damn thing (you need to take two paces backwards!).
I've just put it on the K5 and it's happily working with a pentax M 1:2 50mm
I just put an M42 converter ring in the end of it and screwed a Zeiss 50mm on and that is OK too.
I'll have a play with it tomorrow (risky, since I might decide to keep it after all!).
