Tamron's new fast primes: Affordable but not cheap (pictures and photo samples)

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.

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

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.

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

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

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.

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

The lens is quite sharp.

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

Here you can see the quality of the focus transitions.

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

Both lenses can focus quite close.
