What lens and camera?

~Steve

Sony Nex-3 camera

Top pics were taken with the standard 18-55mm lens that is included with the camera, at 55mm setting. Lower with a new 35mm macro lens. Of course the lighting also differed, but I'd been trying to take pics of these very worn coins with poor surfaces under various lighting conditions for some months and the top pics were the best I ever arrived at. The bottom pics were basically my first attempt with a new lens. Admittedly they were taken with relatively low-angle lighting (about 30 degrees) to accentuate the relief, but I'd tried low-angle lighting before and only got a brown blur / green blur respectively.

To be honest, the top pics probably reflect how visible the coins in hand, i.e. virtually invisible due to their camouflage patinas, but I wanted to see the designs, given the rarity of the types (6 known of the top type outside the Paris collection; 3 of the bottom type), and much better colour-distinction from among the camouflage (ie. among the various shades of green and brown). I'm happy with the results.

This the lens: it's an "e-mount" lens specifically designed for the NEX cameras:

Thanks Andrerw!

The macro lenses are the way to go!

I have an old manual one for my Nikon, and even though the metering and focusing are trial and error, the result is still better than the standard lens that came with the camera.

Someday I want to get one of the current macro lenses that are designed for the camera. It's all a matter of priority ::) Right now new coins seem to be winning the tug of war ;)
