I'm a newbie and t his is the second time reading about non-macro version. I ordered mine and was surprised to find the "Macro" on the label.
enlighten me.
thanks.
My copy is exactly as yours, there is a difference however, between a true macro lens that is designed specifically for close focus work, and flat field focusing, and a normal lens, or zoom lens that can close focus.
There are tons of trade offs in lens design, but the ability to close focus is a selling point. The lens can focus incredibly close at 75mm, hence it gets called macro, and it will be fine for macro work in general, providing a) you stop down, and b) you are not copying flat objects at maximum magnification.
That is why I asked if the OP had decided that this was to be used specifically as a macro lens or not. He is asking for a rediculous performance out of an otherwise fine lens. and then bitching about it when it can't do it.
This lens costs considerably less than a true macro lens for one reason only,
it was never intended to be a true macro lens. As an aside, a forum member who knew I was looking for a pentax 200mm macro sent me a PM offering me on of the two that he had. I appreciated the gesture, but note that the market price of this lens
used is 5 times what I paid for the tamron.
