I have two zoom lens in same range Pentax K 85-210 f3.5 and Tamron Adaptall-2 SP 80-200mm f2.8.
I carried out tests on these two zoom lens to determine which is better. I found that sharpness and color wise they are very very close to each other.
I thinking of selling the Pentax K 85-210mm f 3.5 lens since the tamron is slightly faster and I can use PKA adaptor to get A functionality.
Can somebody give me idea how much is the Pentax K 85-210 f 3.5 lens worth. I do not have close focus adaptor lens but the lens itself is in very good condition with minimal signs of usage.
