IMHO if one is willing to go manual focus one might as well get an 85 PC Micro-Nikkor and get the PC aspect as a bonus. The older model may even be a bargain but I have not checked recent prices.
ps. I checked. Non E version going for under $700 US at auction. That is quite a bargain as I recall paying over $1000 over a decade ago for mine new. New ones are quite a bit more now.
I will disagree with this one. The PC-E Micro-Nikkor while being impressive in terms of sharpness, exhibits large amounts of LoCa. The focus throw is also tiny. Getting good hand held results is very very difficult. These 2 reasons made me sell my copy. The older version is pretty good as well, but has the same issues.
When I first got the lens, I thought my copy had issues. It was not until I put the lens on a tripod, which it revealed itself to be extremely sharp and capable. The focus confirmation dot was also inaccurate. From then, I used it on a tripod, and subsequently sold it after acquiring a 24mm PC-E for a bargain price, one knob of that lens is broken. The 24mm nearly goes to 1:2, making it a very interesting lens. If Canon calls their 1:3 old 90mm "macro", then this 24mm certainly deserves that designation.
Here's my thoughts on the CV 95mm:
It's a very small lens, and very sharp wide open. The colours are really nice. Focus throw is also adequate.
This lens VS the 85mm 1.8 really goes down to what the OP wants. I'd personally go with the 85 for portraits, and the 90 if I shoot primarily macro and want some portrait capabilities. I sold mine due to lack of use after purchasing the 85mm PC-E.
I have a small album on the 90mm CV:

I think the 45mm PC-E would be perfect for me. Dunno, too expensive.
