Ted, this is the direction I've been heading towards, although frankly I don't trust my focussing ability to shoot at maximum aperture unless I'm forced to by light conditions. I started with the 1/focal length rule, then it dawned on me that I simply wasn't getting the best performance from my lens. In saying this, I am aware (of course) that the dictates of depth of field for particular shots mean that I won't invariably use this approach. In addition, I use an older (1970s) 50mm Summicron - so Erwin's test results tell me that it will not perform as well as the new 50mms at full aperture. I'm using a Nikon soft release on my M6. Only one I could find easily in Australia. As Ted says, it is a percentage game. I've had some shots work at 1/15 second with an SLR. Some shots. But you loose a heap of shots as well, due to camera shake or subject movement. I've also tested out my M6 in some horrendous lighting conditions and it has produced shots I don't think you'd be able to get with any other camera. What did interest me about Erwin's report was the suggestion that performance of a 70-180 zoom continued to improve at (from memory) 1/2000 s and 1/4000 s. You apply the 1/focal length rule and it says 1/250 should be ok - 1/500s great etc. One direction all this can lead you in (as far as photojournalism is concerned) is to move to films like Fuji Neopan 1600, as standard. A couple of extra stops, but still relatively fine grain, to enable you to use faster shutter speeds. With most landscapes, where depth of field won't be an issue, I think I'll just shoot a stop or two down from maximum aperture. BTW, has anyone tried travelling with Neopan 1600? Can it survive repeated Xrays in thick lead bag? I'm travelling to China, taking a lot of internal flights, and I'm concerned I might be refused a hand inspection. Oh and on the issue of the size of enlargements. I work on the theory that potentially I could want to enlarge a shot up to 20 x 24. 99% shots I won't, of course. But you never know when you might be taking your world famous shot.
