camera kit: more fine tuning

As I noted in a recent post, the lens set that I have is quite excellent and satisfactory. I still place low bids now and then, and to my surprise I won a 100-300 Quantaray. It is a clone of an earlier Sigma that I had, and it rivals the Pentax DA55-300 but with lower contrast and f/6.7 above 220mm; it's full-frame friendly and has an aperture ring, so it has uses with film bodies and great potential if Pentax takes the hint and releases a FF 36x24-sensor camera. Until such moments arise it really has no great use to me, but it is a bit more compact and focuses faster than the 55-300. I guess lower bids are in order though! One can make a nice pairing of the 28-105 and 100-300, but neither of those lenses are kept in immediate reach very often - I guess "top-shelf" optics means that I put them further out of reach, so it's not the compliment that the label suggests. Another addition is on its way, and again it's an old favorite: the SMC-M 200mm f/4. Since the 70-150 was my highest focal length in manual-focus gear, this was a nice (re)addition; I can now use 28, 70-150 and 200 manual-focus lenses to make a nice primal set. To round it out, AF primes at 15 and 50mm and the SMC-M 135/3.5 (also on the top shelf) can be added.
