    Well work got cancelled due to a freak spring snow storm and power outages, so I'm just at home playing around with my lenses. Decided to try a bg blur test with my "portrait" lenses. I have kids, so I just used what was available to me, with stuffed animals as the bokeh target. :) 

    This is 30% view and exif is tagged in each. First is a test with a close background (about .5m behind book). Second is a more distant target (about 4m behind book). Wanted to try something outdoors, and maybe real portraits - but like I said, the weather sucks.

    As this is indoors, you can see the exposure differences between them in the EXIF, too. F2.8 zoom at a major disadvantage. (And the -2/3 Ex Comp was an accident). I did the 35-100mm both at a similar length to the primes, and then at a bit longer length to try to make up for slower aperture. Still no contest vs the 56mm, though.

    No big surprises. You don't need to apologize for the 35-100 though. It's not bad, just can't hang with the primes.

    One more. I was hoping forhighlight " bokeh balls", but they are kind of hard to see (lamp and blinds at right). All of these lenses seem to have really smooth bokeh.

    One more non-perfect comparison when I was out with the kids tonight. The Olympus really holds it's own against the Sigma. The difference in blur seems mostly down to the perspective compression. I didn't get a close enough shot from the 35-100 to include it. I will say with tracking the kids around at dusk, the Olympus and Sigma had no problem nailing every shot while the 35-100 missed every other shot.

    Love these primes - getting very high shutter speeds (maybe too high on Sigma shot as it's under exposed) and still at base ISO after the sun is down! :)
