Dear all,
First of all, a big THANK YOU for the very helpful advice and your time. I very much appreciate that.
I have played around with the S2 and the SF58 this weekend, using David’s advice of manual setting, and was quite pleased with the results. Will try next weekend with even lower shutter speeds. Also, I am about to order the Garry Feng diffuser and this should improve matters even further. So I am planning to use the S2 as my prime camera (shooting will be mostly indoors–the weather in Brussels in early December is unlikely inviting for outdoor shooting). I am using the system nor since February and feel reasonable comfortable, but will keep things simple.
I will also take the M9 with a 50 lux and a 35 or 28 cron, as these lenses for me produces the best comprise between speed and focusing. I probably leave at home the 75 lux or the 50 f1, as I am likely to miss too many shots–less than perfect eyesight and bad light do not go together well. (OTOH, some shots may look good even if a bit soft).
The main objective of the shooting will be to capture a few shots of the ceremony, and then candids during reception, lunch, and the party, something I feel quite comfortable shooting. And I am not the only shooter anyway.
As regards razor sharpness, the good thing is that this time the bride wears a beard :D.
Again, many thanks for the helpful advice!
Georg
