Good information - thanks!

Jchrome - I actually had the chrome one made (why I'm keeping it), so I haven't had time to brass it yet. Considering it's done with motorcycle-style chrome, I'll probably wear out before it does. Also, don't try this at home; the heat of real plating can really damage the covers, and these had to be straightened quite a bit. I also lost two cameras worth of covers in the process (hence the parts unit I have...). I studied the GL690 for this project, but they are too expensive to use for that.
Otherwise, I am pretty indifferent. The one thing I like better about the BLs is that the initial wind-on requires a lot less leader. The VF is also a little wider in view, and you get a dark-slide indicator (for what it's worth).
Thanks for the kind words on the writeups - I still have to do the 150mm, which has been on my plate for a while.
Best,
Dante

Game on in the classifieds.
I wouldn't mind the auto-up for my 100/3.5 AE. The darkslide in my 670 body is so fussy (snappy, but gets stuck closed) that I wouldn't chance swapping lenses mid-roll anyway.
Hrm, I haven't tried that, but will keep it in mind next time it gets stuck. For some reason or another, it just doesn't like to spring back if it has been closed and left that way...but if I wind it up to the point just before it latches and let it go, it snaps open like it's new.
I suspect this is a common problem. I took my 690BL to Nippon Photo Clinic because the shutter wouldn't fire and they claimed it was because the curtain wouldn't come back all the way. They said lubrication was the ticket to making it work better.
I just finesse it back open now.

50mm f/5.6 for a reasonable price........
I think I've hit on why the GW series has the noise it has.
I posted this to the Camerapedia article:
'When tripping the shutter, the noise is curiously loud for a camera with a leaf shutter. Some mistakenly blame the odometer on the bottom of the camera (which is a falsehood that has spread far across the web). However, it was discovered that the noise is not due to the shutter nor the odometer, but rather to the winding mechanism and it's linkage with the shutter.[8]
With 'normal' leaf shutters (such as the Copal or Seiko shutters for large format lenses), the winding mechanism and the power storage is contained within the shutter. For the GW690 series, Fuji moved the power storage (specifically a spring which contains the power to actuate the shutter) from within the lens body to within the top plate of the camera body. The vibration from the release of the shutter causes a 'hum'.
As expected, the interchangeable lens G/BL/GL models do not have this shutter noise due to the power storage and release residing within the lens body.'
What's the reference for that? I've never heard of a leaf shutter whose source of power is that far from the point of actuation. I'll dig up my GSW690III service manual when I get home, but this sounds kind of weird.

The GW690's interface is powering the shutter.
Nonsense. I've had that shutter out of the lens for repair - it is a perfectly normal Seiko Copal, as used by Mamiya as well, driven by its internal spring.
