Minor, "just in case" clarification: only Av has the maximum aperture limitation; M allows you to use the lens on all stops. Welcome to the list. I had a SMC Pentax M80-200/4.5 and a SMC Pentax A70-210/4. I sold them both because they were too long and unwieldy for my liking. My perceived benefit of AF is not necessarily that it will nail the focus, but that you get help with focussing; like a third hand. I don't have a DSLR (thus the DA50-200 is not an option for me), so I tried hard and for a long time to find an SMC Pentax F70-210/4-5.6. Note that SMC is important in the case of these A and F lenses; Pentax also marketed A and F 70-200 (no typo, 200) which are considered inferior. I know nothing about the Series 1 lenses in practice; still I would avoid the Cosina and get the (early) M80-200/4.5 instead as a stop-gap, assuming that I could get used to the stop-down metering P.J. described. There is also a M70-150/4 that is very light and affordable but reportedly suffers from barel distortion. Not sure how it fares on the cropped-imge DSLRs.
