The Tamron SP Adaptall-2 90mm f/2.5 Macro (model 52B/52BB), a lens highly acclaimed for its exceptional sharpness, beautiful bokeh, and remarkable versatility with its Adaptall mount, is a "cult classic" among photographers. Praised for both its macro and portrait photography capability, the lens was first introduced in 1979, with an 8-element in 6 groups design and 8 aperture blades, BBAR Multi-Layer coating, a minimum focusing distance of 0.39 meters, and a f/2 magnification ratio (extendable to f/1 with an optional extension tube or teleconverter).
The lens, an innovation by Tamron that revolutionized the concept of a portrait macro lens with macro capabilities and medium telephoto functionality, underwent a cosmetic redesign in 1988, with the introduction of the follow-up Model 52BB. Though with the same optical formula, the update was a mixed plastic and metal construction, rubber focusing ring, a plastic window over the focus scale, 9 aperture blades, and takes 55mm filters (49mm on the 52B). The lens is also lighter by weight than the predecessor (440 grams for the 52B, and 410 grams for the 52BB).
On image quality, the Tamron SP Adaptall-2 90mm f/2.5 Macro is reportedly extremely sharp even wide open at its widest f/2.5 aperture, with optimal performance at f/8. The lens is also capable of producing "beautiful, smooth bokeh" with background rendering that is particularly praised for portrait work, and equally noted for "natural color reproduction" and excellent "chromatic aberration control".
Album Images
As part of the Adaptall-2 mount system, the Tamron SP Adaptall-2 90mm f/2.5 Macro can be used with virtually most 35mm SLR cameras available on the market through interchangeable adapters, out of which 26 (adapters) were produced by Tamron and third-party manufacturers. This adaptability is also one of the factors that has enhanced the popularity of the lens, as enthusiasts can continue using it even when changing camera systems.
Images here were shot on the Nikon D200, a 10.2MP CCD digital SLR camera, released in 2005. The camera is known for its robust build quality, comprehensive feature set, and excellent ergonomics. It was introduced as a semi-professional model positioned between entry-level D40 and D80, and the high-end D2Hs and D2Xs. The camera is particularly praised for its CCD sensor, which delivers detailed images with a film-like aesthetic, especially at higher ISO settings.
On the Nikon D200, with its 1.5x APS-C crop-sensor, the Tamron SP Adaptall-2 90mm f/2.5 Macro will behave like a 135mm medium telephoto or a catwalk lens. Similarly, on a 1.6x crop factor (like many Canon APS-C cameras), it will be like a 144mm lens, an excellent choice, with its moderate compression and shallow depth of field, for portraits, street photography, and landscape photography. In certain situations, the lens is also a good option for sports and wildlife photography, as well as for the product and food photography genre.
