6x7 135 f4 Macro Lens

It seems I've read somewhere that the 6x7 135 f4 lens wasn't sharp after a certain distance. I don't recall if that distance was mentioned but it seems it wasn't very far. It ought to be a decent portrait lens at least. Anyone know of this?

The 135/4 macro is not really a "macro" lens but more of a "close-up" lens. It's not bad in that regard, but is no where near as sharp as the 100/4 macro.

I have not tried using it for portrait work, as the 150/2.8, 165/2.8 or 165/4LS are better suited.

I've had the 165 f2.8 and knew it probably wouldn't be as sharp as it but thought it could still render good close ups as well as portraits.

The 135 macro is corrected for close work so there is going to be some spherical aberration at infinity. This can be compensated by stopping down to mid apertures. This lens actually does fairly well for landscape work when stopped down. Its f/32 comes in handy for large DOF shots.

The reason I had considered it was for close up work-not necessarily macro work and as a stand in for the occasional portrait. I had one of these many years ago and best I recall it did well for both...a Takumar lens. The one I was considering is the later SMC lens. I hadn't considered it for anything past about 20 feet at best.
