I feel an obligation to post this just to provide a different perspective from all the rave reviews of this lens which are all over the Internet

Here's what I found:

The AF speed on the 75/1.8 is noticeably slower than the PL 25/1.4. Most reviewers say it's "acceptable". I disagree. The AF is slow enough to render useless the C-AF Tracking mode for Continuous Shooting on my E-PM2. Results may differ on other bodies. I personally find the C-AF TR CS mode to be a DSLR-killer when photographing kids who are "moving around a lot but not running towards the camera", when used with the 25/1.4, but with the 75/1.8 the C-AF TR mode devolves into a useless gimmick.

If you shoot this lens at the same distance as the 25/1.4, the 25 is likely to be faster yes. However, that's not a fair comparison since the magnification of the 75 will be three times higher and the amount the AF system has to move to keep focus much greater. If shot at the same magnification rather than the same distance, I doubt that the 25/1.4 will beat the 75/1.8 for AF speed. Here's what Lenstip has to say about the two in that regard:

25/1.4

The autofocus of the tested lens is silent, quite fast and accurate. In studio conditions we didn’t have one single miss. Running through the whole distance scale takes about 0.7-0.8 of a second. There were no problems whatsoever with front or back focus either.

75/1.8

The tested lens is equipped in a very efficient focusing mechanism, based on MSC technology (Movie and Still Compatible). Its work is beyond reproach. Even on an older model, such as the E-PL1, it works silently and so efficiently that focusing rarely takes more than 0.5 of a second.

The accuracy of the autofocus is also splendid. In studio conditions the lens didn’t miss at all! What’s more, even if you make the definition of an error more strict and you change the limit from 20% to 10% deviations (as, traditionally, a miss means a measurement which diverge from the maximum result, reached at a given aperture, by over 20% ) there will be still no misses!

This is touted as a portrait lens, but I find it too sharp for portraits of adult female family members. I had to apply a Soft Focus effect before I could show my wife the test photos I took of her. Results may differ if you use a professional make-up artist, or photographing kids with perfect skin.

When a lens is too sharp for your taste, this is easily fixed in the manner you describe. When it's not sharp enough, that's harder to fix. For this reason, I'd rather not have softness built into the lens itself.

The focal length really is too long for family photos. It is difficult to compose in a typical household setting, where walls and furniture gets in the way, and it's difficult to compose when in a family activity outdoors, because you need to step away at least 10-20 feet. And if I'm going to be outside I'd rather carry a zoom, or the 25/1.4 to capture some environmental context with just enough blur.

Correct. This FL is appropriate for halls rather than rooms and, of course, for outdoor use.

Generally speaking the 75/1.8 does nothing to improve the quality of OOC JPEGs. There's still the issue of skin tones (see my other threads). I was hoping it might somehow outperform the 25/1.4 in color rendition and fix the skin tone issue, but it doesn't, it's just sharper.

I wouldn't expect a change of lens to fix skin tones.

The 75/1.8 now costs the same as a D7000. It has put my whole commitment to m43 into question... I was initially thinking to dump the DSLR, now I'm more inclined to keep both systems, with each doing what it's best at. D7000 for indoor and non-environmental portraits. E-PM2 for everything else, including, environmental portraits.

Your choice of course.

I hate having to return lenses. Does anybody know if I would find the 45/1.8 useful based on the above comments? Is anybody else using C-AF TR on an E-PM2?

Inside an ordinary house/apartment, you are likely to find the 45/1.8 far more useful than the 75/1.8.
