Info on Pentax-A 70-210mm zoom please
It has a fixed max aperture - f4 - at all focal lengths.
Many people consider this lens to be as good as, or even better than, the F 70-210, which itself is an excellent lens.
So if it's in good nick, it's a good buy. But it's not a macro.
Boz's site has the specs.

Where did you get the impression that this lens is a macro? I have never seen that suggested before. The max magnification is .25, so a macro it aint.

You beat me too it George
I was checking out a couple of sites trying to figure out the Macro thing and couldn't find anything :

the F 70-210, which itself is an excellent lens.
I have my eye on one these at the moment on E-bay, it has a day to run with no bids and is bundled with a bunch of other junk. Its sitting on 30bucks and would be a bargain if i can grab it.

Generally, I only use two zooms, and it's one of them. I bought mine as part of a bundle, too. They quite often come with SFX bodies.

On the focusing ring it says "Macro" which I assumed means there is, apparently, a setting for Macro. Problem is that I cannot access it

I'll think of something someday.
It's a beautiful item. I had one. However, by modern standards it is rather long and heavy, and I don't think it's sharper than the much smaller and lighter DA 50-200mm. At least it wasn't when I compared them focused on a suject about three or four yards away.

Need to zoom out to 70mm to use the "Macro" focusing.
Thanks for the info.

It does say Macro and from what i can make out it goes down to 1.2
When you zoom it out to its limit (on some lenses i have seen) you twist it and jumps out to its macro position. I could be way off track here :

To access the macro setting, you simply turn the focusing ring after zooming out to 70mm. Slightly more force than usual is needed to get it on to the green (macro) section, if I remember rightly.
By gosh I've done it Thanks again for the help.

I presume that the aperture at full zoom is 5.6 (that much I gleaned from the web), but am I right?
Also, what is meant by "macro" in this instance? Is it 1:1, or some more dilute interpretation?
I like the one touch sliding/rotating zoom/focus and the inbuilt lens hood, but not the fact that the front of the lens rotates - no screw-on polarisers or grad filters there then.
It also makes up for the fact that I sold off all my old manual lenses a few years back - a decision I have regretted ever since.
Any help much appreciated.
Regards
Graham
