  • Tamron SP 28-80mm F/3.5-4.2 Model 27A: This lens definitely is an above average performer within its class even when compared to OEM lenses of the same era. Optimal optical performance is F/8 to F/11 at all zoom settings, and at these apertures this lens is very sharp. Macro performance is good between F/8 and F/22, but with a moderate drop of contrast in fine details towards the edges of the film plane. This is a very versatile lens which nicely covers the wide angle to slight telephoto zoom range, and which features decent built-in macro performance at the 80mm zoom position when using smaller apertures.
