After several attempts i can take this picture with a relative focus area. This is very dificult because i was using an inverted lens and the focus area, even at f16, is really smal, like one centimeter. And using close apertures... i must obturate slow... in seconds for light compensation.
So... for this i use a russian lens, Helios 44m-4 58mm f2 inverted without adapter, only near to the camera.
5 Seconds, f11 and iso400
I am happy with the result and the spider is in the garden right now.
