Hey Folks, Looooong time reader to this list, although I tend to be very sporadic. (By the way, sorry if this is a duplicate posting, but I reposted in plain text in case it was necessary.)
So, I do a lot of plant macro work for stock photography. I never use my camera off-tripod. Also, with my K7 (my primary camera body), I always shoot with locking the mirror up first, by either using the 2-sec lock up, or in live view mode. ANYWAY, my mid-length camera lens of choice has long been the 90 mm Tamron F/2.8 manual focus. My wife is starting to use this a lot for butterflies, but would like an autofocus lens of the same approximate length. By the way, Ive learned to hate the adaptall mount, as Ive gone through a couple, even though my lens is working great. So, I see that there is a Tamron AF 90 mm f/2.8 Di SP A/M lens on Amazon and the other usual markets, for about $438. There are also two Pentax f/2.8 100mm lenses, a WR FA smc for about $650, and a D FA for about $850. For complete clarity, Ill include Amazon links to the three lenses below. So, to the Pentax gods and prophets here, I pose my questions. 1) Im correct in thinking that all three lenses are autofocus, but can be used in manual focus too, right? 2) The Tamron for Pentax does not need a damnable adaptall mount, does it? 3) What is the skinny on how these lenses all perform? Your wisdom is most appreciated!!!!
