I have a chance to pick up an older Canon EF70-210mm f/4 macro lens pretty cheap. Does any one know what the magnification is on this lens, is it 1 to 1?and is this lens any good?

second question. Will a the Canon 1.4x teleconverter work with the Sigma EX 70-200mm f/2.8 APO lens? Or on the other hand with the Sigma 1.4x teleconverter with the Canon lensmention above.

May be - The Sigma works on the newer Canon lenses, but I'm not sure about the olderone though :O

There are several links in the forum on this lens. The best is

http://www.stevesforums.com/forums/v...ight=EF+70-210

I have this lens and it is a good lens. One of the first lens I ever purchased for my Canon 620. Bought it Ritz for about $130 I believelate 80's??? Its been a while. It is a sharp lens but focus is slow and its the old push pull system to zoom. It does not have a lock on the zoom so you have to adjust regularly and you can't let it hang down or it will extend out completely. I use it occasionally but I have the 70-200L F4 now and it is in my relic bin. I take it out when conditions are iffy and I don't want to risk by L lens. I use an old kenko 1.2 teleconverter on it and it works fine.

thanks guys for the responses. and the link, which I found that it is a true macro, but the bad news was the zoom sliding out when pointed down. Think I'll pass on this lens and fork over the bucks for a macro lens that was built after the ice age.

Hey, I'm old but not that old!

Actually, it is a good lens, but has some querks. I have the 60mm EFS and it does great but as others have mentioned some "live" subjects get "skittish" if you get too close makingthem difficult to capture. I am now looking at the Canon 100mm Macro, but may hold out for something longer when my budget recovers from the Tokina 124.

I'm old too Ctrack, and I have heard that it is a pretty good lens, just don't like the fact that the zoom slide out when pointing down, and was pretty much looking for a life size macro, and most things I would be shooting I would be looking down at.

I generally hold the zoom when I shoot so its not a problem. However, when you think about it, using a tripod would be an issue with Zoom creep. The new technology is so much better (functionally not necessarily optically) than the original EOS lenses.

Hope you get a find what your looking for.

One thing at least positive about this lens is that it was parafocal in design -> i.e. it'll hold its focus when zooming in or out. This feature has since disappeared from most if not all of Canon line of zooms, as they are mostly varifocal for the sake of weight and compactness - One now needs to go to 3rd party (or Nikon) for such a feature
