About the 'feel' of the motor's two shutter buttons. It's a bit touchy-feely, but please bear with me. The R8's top plate shutter button feels quite mechanical to me, although it certainly has electronic characteristics. In ways, it's similar to my R6.2's truly mechanical shutter. An F5 has what I would call an 'electronic feel' to its two stage the shutter button, ie, beyond the first stage, there is an imperceptible point where the electical contact must be made to complete the circuit that fires the shutter. The second stage is like pushing down on a spring with the shutter going off half way through the push. Once you've got that point nailed, you can fire the shutter at will with the slightest pressure adjustment. Q. How do the R8 motor shutter buttons 'feel'? I've imagined they'd be similar to my description of the F5 button, although with three stages instead of Nikon's two. Now, to get a little more touchy-feely, I've noticed something very interesting with my R8 and R6.2 shutters. They have three stages, yes? No! Mine have four! Firstly, the R8. The book says: first stage - meter on; second stage - lock exposure; third stage - fire shutter. Well, with my R8 I have a tiny initial stage as part of the third stage. It works a little like a set trigger on a rifle, just doesn't hold there once set of course. If I want I can choose to be gentle with the shutter and exploit this 'set trigger'. Its great for portraits and low shutter speed work. Or I can just push through the third stage in one go, such as with action shots. Now, the R6.2. It's a little different, although still a three stage system. Here, the second stage comprises two parts, with the earlier part longer than the later and with a very slight pressure threshold between the two. Also, this subdivision is detectable the first time the shutter is taken down to the end of the second stage, but if I release the button and go again, the subdivision is gone and the stage becomes one smooth push. Go into the third stage and the shutter fires immediately. I find the effect described for the R8 to be quite useful and consistent from shot to shot. But it takes a gentle finger. With the R6.2, it's more something to simply keep in mind, because the effect changes if the shutter is nearly fired. I've noticed this effect on a number of R8's. It's there on the two R6.2's I've used. I'm not imagining this! One Leica technician I discussed this with couldn't feel it, so maybe it's just my wiring. So, Ted, and others, get your R's out and squeeze. How do they feel? Regards Rick Dykstra
