I complain about the paucity of 65's for the G690s, but there're always a lot of GSWs. With those, you get the (possibly better?) 65/5.6 and a free camera. You just can't take it off of the lens. I've got half a mind to send the incoming 65/8 back if it isn't stellar (i.e. mostly free of haze & fungus and more or less optically centered) and just sit on the money until I've got a chance to scoop up a 50. After all, the 50 and 180 are the reasons I chose the older interchangeable-lens model camera in the first place.
Regarding the 'silenced elegance' - maybe it's just the shutter in my 100mm, but while it lacks a loud clack as the GWs are purported to have, it does make a higher-pitched 'twang' sound each time it fires. I have a Nikon FM that makes a very similar sound. It's not shocking, but definitely loud & unusual enough to draw attention.
