3. Challenged notwithstanding, Lois, I posted this because this looks to be a very good lens.

I'm not a Canon user, but I can appreciate its advantages, one of which would be the benefit of taking a picture and having the background blurry so that the main subject stands out. But thanks anyhow.

2. Well, did you get one? Oh aren't you an Olympus person?

Just some thoughts.

1. I don't go for high speed lenses. We're not using film any more (well, I do on the side).
You can kick up the ISO a fair amount to gain sharpness from higher shutter speed and not get "grainy" with a good sensor.

2. From the DPR site:

the samples we've taken so far suggest it exhibits quite significant vignetting, as you open the aperture up. The lens also requires the use of distortion correction as part of its design.


Taming these optically (and not just in software) costs money in the design and optics. I don't know how well software "undoes" these defects.

I won't ramble. That must be the reason it's inexpensive.

In this case, less info is more, I think. Too many charts and graphs.

4. Yep, Ken can go overboard. Nope, I'm not getting one. Olympus fills my needs. But

I posted because I imagine DOF might be nice at f/1.2 and thought Canon users might be curious. Thanks!

5. Yes indeed. The 1.2 gets you real selective focus.

And in that case, it's likely that vignetting might help and distortion might be not noticeable at all.

Thoughtful of you!

6. Thanks brother!
