catza.net photos: Tamron SP AF 28-75mm f/2.8 XR Di LD Aspherical Macro

• rather typical zoom lens for hobbyists
• estimated retail price 415 EUR
• in my use from 4/2006 to 11/2008
• got replaced by primes to get sharper photos on large apertures

• has a focal length range (28 mm - 75 mm) that fits nice with 1.6x crop body for cat show photography
• offers constant maximum aperture over the focal length range which is a must for using manual exposure mode
• very lightweight
• focuses rather close (“Macro” stands for that)
• has a good reputation to be the best lens in its class

• like most zooms soft wide open compared to primes (starts to work better at f/5.6)
• not as usable in cat show photography as I thought
• all plastic except the metallic EF mount
• the focusing motor is a little slow
• although carries “Macro” label isn't a real macro lens
