I'll look forward to your impressions concerning long exposures.
I shot,briefly,last night the Montreal skyline with a P45 and ended up using exposure times
in the 60-90 second range@ iso 100. Noise was,for all intents and purposes, not evident even after
dialing,way back,the default noise and banding settings in CaptureOne.
I used the back on a Hasselblad Arcbody with 45mm (non digital) and the sharpness was
extremely impressive-easily the most detailed digital capture I've yet made,or seen.
Individual brick detail could be seen in buildings a kilometer away.
Assuming that digitally optimized lenses should add another degree of resolving ability is
difficult to imagine without seeing firsthand.
