An error in the focusing action only the thickness of film can cause gross focusing errors on the final shot in digital. The thickness of film itself accounts for this. This is an issue that folks who bought the RD1 and the M8 had to find out the hard way by having some of their lenses collimated to their camera bodies. The 90 TE is one of those that's really sensitive to focus errors I and others have found. As for the lens itself, it's a great performer. it has an issue with flare when very bright areas or light sources are in the frame or light is hitting the front element at a sharp angle outside the image area. There's also the regular issue of Leica lens haze and then the rear element etching which was unique to some early TE lenses. It's not a dog at all. It's a great, very portable and very capable lens but now that digital has changed the game, the 90TE has become much more difficult to use.
