The new telephoto prime has the elegant design of the SP series.
Both lenses have nine rounded aperture blades for smooth out-of-focus areas.
The macro has three focus-limiter settings, with the close-up range setting from 0.3 meters or 11.8 inches to 0.5m or 20 in. That's a good limiting range for macro photography.
The updated 90mm macro looks much more modern than its predecessor.
The Tamron lenses have large, easier to feel switches.
