I decided to see how close I could get with 60mm of extension tubes the other day. I expected to achieve the greatest magnification with the 150mm f4 PQS lens but I couldn't get close enough. The 180mm f2.8 PQ went rather soft close up - not suitable. In the end, the humble 80mm f2.8 PQS lens won because I could get really close, with great sharpness.
ISO 50, f11.
