Anyone hazard a guess at what the white spots are on some of the coins? Dried skin. bacterial growth, something illegal ..... ????

+1 if you have to use a tripod.

For indoor macro, an alternative is to use a big clamp with mounting screw on top (mine's Novoflex, other brands are available :wink, tightly clamped to the edge of a sturdy table or other work surface. Focus rack and camera on top, rock solid, can't topple over. Works well for me atttached to a kitchen work surface. The only drawback is that in the interests of domestic harmony and me not going hungry, it has to be cleared away when I've finished .

Steve

Oops, last but one sentence should have been '... on the 300mm'.

Steve

Depends on progress with domestic duties...

I'm going to have another go in a few days time, trying to focus as accurately as possible and with a less well rubbed penny! These were done using the camera screen but will try the flucard to get a bigger image on the tablet. 1/8 mm steps on the focus rack (Novoflex) should be possible in principle, perhaps a bit better if I'm really careful.

At the back of my mind is creeping up to reversing a 24mm on 300mm + 1.4 TC and attaching a Q via the Q/K adapter. That means approx 17x magnification and extracting the centre of the magnified image with lots of closely packed pixels. And there's always the possibility of reversing the Q 01 8mm prime on the 30mm. But the aberrations, vibrations, depth of field, diffraction ...

Steve

You're right - it's a metaphorical scream. I wish my window did the same, I could cope with that at 3am.

Steve

And now with the 1.4 TC inserted between lenses and camera... Again, straight from camera, not cropped, no post processing.




Too late to do any more this evening. More experimenting to come another day...

High praise from someone who specialises in the details of a fly's eye! Thank you, appreciated.

Steve

Trying out the new rings, just an experiment...

F50mm f1.7 @ f11 reversed on DA*300mm. Straight out of camera, not cropped, no post processing.




This is fun!

Steve

That was a quick response! Thanks. I'd checked the internal seals and couldn't see a problem, also the external seals looked OK through the glass, hence asking the question. Can't check the mastic until the wind and temperature are suitable for getting the ladder out.

But thanks to the mastic suggestion, I can now see that the cause might be a gap (couple of mm) between two tiles that are part of the external window ledge. Should be mortar in the gap but most of it has gone (or perhaps was never there...). Only one way to find out, and that involves a ladder and a tube of goo... then waiting for a strong easterly.

Steve

Does anyone else have a double glazed window that howls like a banshee when the wind blows full on? It's in our bedroom, not much fun at 3am, particularly when you were reading a Terry Pratchett book last night that features a banshee which screams "OOOeeeOOOeeeOOOeee".

Can it be stopped (without using an exorcist)?

Steve

Well, seeing as how:
a) earlier this week I ordered some coupling rings and other bits and pieces to see how much usable magnification could be squeezed out of the lens collection; and
b) since placing the order I've been wondering what to use for the first subject...
... it would be perverse to refuse this invitation.
