"The Model 107B is the original version of Tamron's SP 300 F/2.8 which was introduced in 1983. It was beautiful, expensive and is very rare since so very few were made during its one year production run. It does not feature the internal focus (IF) found in the later versions of this lens, but features very robust construction and is slightly heavier. This rare lens was finished in gloss white, is a very good lens for low light telephoto work, and is highly sought after as a collector's item. Two low dispersion (LD) elements are used in this lens, which I am pretty sure are the first (front) and the third element in the above optical layout. This lens also features a spherical aberration compensator group (the cemented doublet in the middle of the lens) which assures crisp images even at close focus distances." -
