Sitting next to me right now is a Yashica Lynx 14 IC (There are two. The first is just a Lynx 14. It has a meter on the top and match stick metering. The 14 IC did away with the meter on the top plate and uses an "under / over" lighting scheme in the viewfinder like the electros...) I just got back from the lab where I picked up some Ilford XP2 prints from Thanksgiving. Very nice (didn't get a CD for these or I would put up some samples...)
This is rapidly becomimg my "go to" camera despite its down sides. It's large, it's heavy, its lens is flare prone (see my next post for a recommendation on this...)
However, there is no other rangefinder that has a f1.4 lens and a leaf shutter. Not even a Leica. It is a /very/ unique camera - one of a kind really, and it has practical applications. And, yes, that extra bit over the GSN or other 1.7/8 lenses means a lot. The lens is very sharp and optimized to wider apertures.
This is one of the very best cameras for natural light candids. This is a serious lens on this camera, and its parralex corrected frameline + leaf shutter + manual control + 7 element f1.4 lens results in a camera capable of some serious stuff. This ain't no toy.
It takes a bit of getting used to. You need to get used to the weight, and need to use it enough to become "one" (sorry) with it... that is, know where to reach on the lens barrel to focus, set shutter speed, and set aperture. As a fully manual camera, you can use it both as a shutter priority /and/ an aperture priority.
Get the best sample you can find, send it off to Greyhoundman (check with him first), or Mark Hama, or Essex, or any competent repair shop. Bit the bullet and have it CLA'd/repaired/restored. Then use it. You might hate it at first but eventually you'll warm up to it. This has become the camera I reach for when shooting 35, even over the wonderful GSN.
