Up close and personal..
Crazy !
Wouldn't it be easier just to get a microscope?? Say a scanning-electron one
Matt
you mean sorta like this
lol kidding, that isn't a penny at all. It's from my MSci project last year. It's long chain hyrodocarbon molecules on a graphite surface. Scanning Tunneling Microscopes are fun
Dan, I salute you, don't thin I can better that without actually resorting to a microscope (though I did see an Oly microscope camera setup on ebay earlier....)
I tried reversing the 18-55 at 18 on the 80-320 with a 2x converter but the viewfinder is so dark you can't see anything.
absolutely excellent shot.. and for the moment I concede your victory..
I decided I'd had enough this evening when I looked at a rig with two lenses, 2 TCs, extention tubes... and wait for it..
2 loo roll insides, taped together to make a 9" ext tube
I'd actually cut slots for tapers, and used insulation tape for a light sealed join and everything. And while I was doing it, I never thought I was in the slightest bit odd.
Length of rig.. around two feet..
I'm going to go and get ready then get a few beers now.. try and restore what little sanity still remains.
Roger's wife is right.. aren't they all if we were honest.
Cheers

Brian, I'm surprised you haven't had a go yet - what about your 400mm with 10-17 reversed
HeHeHe!!! your all insane, maybe try and rig something up tommorow (400 + 12-24 reversed + 90mm extension + bellows + 1.7x + 2x ) if the footie is called off, maybe I can borrow one of their 20000KW floodlights so I can see what I'm doing

LBA is good for you, a Lens a day helps you work, rest and play.

So that's the meaning of life the universe and everyting.
Did you know the average kitchen roll is 9" long. Join 2 of those together and you have 400+12-24+(23mmx2)+1.7x+2x = an electron microscope or 871.4 (for the matmaticians amongst you

I'll just have to believe you Rodger, I gave up trying to do the calculation, been a long tyring week
BTW what will be the minimum focusing distance : ...........................
Only kidding

I'll re-phrase that, could you ALL send me a 'penny'
Happy to keep up the Scottish myths . . . . . . .

Repeat ad infinitum.
That's why I stopped when I did - don't think I didn't contemplate finding another teleconvertor and those other three tubes. Fortunately, the wife was at the station so I had to stop.

I'm still looking for that Sigma 105 you use with devastating effect.
Can't find a decent 2nd-hand version, so might try SRS for a NEW one. Chris is it, at SRS?
Thanks for that, had a good morning in my local woods, the fog disappeared but it left droplets on the few bits of cobweb I could find. The shot of the burrs was actually with my 50-200 Pentax, but I most definitely used the Sigma for the bud.
And yes it is Chris at SRS. Ffordes up your way had a Tamron 90mm last week, don't know if they still have or what it's like, but they always get good reviews. If you're in Inverness, it might be worth popping in.
