45mm lens

The two lenses look identical except for the fact that the 45mm is a bit longer. The gold ring is the SP series' new signature look.

Nine-blade aperture

Both lenses have a nine-blade aperture, though it doesn't look like the blades themselves are rounded.

Well thought-out switches

Both lenses support image stabilization -- not enough wide-ish-angle lenses do for systems from Canon and Nikon that don't have in-body stabilization. As with Sigma's recent designs, the switches are very big and easy to feel without looking.

Relatively big and heavy

The lenses weigh at least a pound, but the 35mm at least is about the same size as Sigma's equivalent.

A little barrel...

...distortion, that is, with the 35mm lens. That's not atypical, though.

45mm f2.2

Note that the sample photos are ones that I quickly shot in our offices. I couldn't take the lenses outside until they were announced. Check back for a wider range of samples post-launch. They were all shot with the Nikon D810.

You can see a little fringing on the high-contrast edges.

45mm bokeh

You can see some rings on the edges of the out-of-focus highlights, but overall they're round and pleasing.

The 35mm lens also produces nice out-of-focus highlights.

I have no complaints about the lens' sharpness at middle apertures.
