nlp,
at this mag. you can't get anything next to it. maybe part of a nickle or dime would work better. like something like this.

That's impressive - so that's what RAM looked like way back when - how things have changed! Out of curiosity, what gauge wire did they use?

Here are two images, the coin is a dime.




These are from my *istDS on my macro rig, yes that is an old drill press!





Distance from camera flange to lens flange is about 235mm, distance from front of lens to object is about 40mm.

Lens is Helios 44mm 2/58.

Coin 0.7sec at F16, almost impossible to focus at wider apertures!

Computer ram 0.3sec at F5.6.

The light is natural winter sunlight on a rather cloudy day and was fluctuating quite a bit.

Impressive is an understatement. Thanks John (and all) for posting the shots and taking time to move tings to take the shots. Incredible. Fantastico.

Robar, it is winter now, I am in New Zealand! :-)



(The hardest part of taking those shots yesterday was to rummage around and find a coin folks would recognise!)

i know john, we're trying to hit 100f here.. what would you say the magnification was on that. the way i figure it is i have a metric ruler, sensor is apprx. 23mm. so if i can see 23mm of the ruler then i'm at 1:1.. if all i can see is 6mm then i'm at 4:1, 50mm at 1:2
