Hi Synthetic, I went from an OM1 too. In fact I still have it and it works great. I used to use it with a Vivitar 70-205mm. A fantastic combination. I like your Dr1 shot. I'm not so sure that you're still practicing! Good luck at the weekend. I've opted for Duxford this year rather than Shoreham for a change. Let's see how it works out. RR
