Guys ive searched but havnt found the answer i understand. If you have a macro 100mm 1:1 f/2.8 for example & use it as a prime lens for say a wedding etc.

How does the 1:1 react in shooting this way ? Will it crop the shot more that if you had just a normal 100mm prime ? (100mm prime may not exist but using it as an example)

    It works just like any other 100mm prime. The Canon version of the 100/2.8 is really really sharp. You need to keep that in mind if you decide to shoot portraits with it, cuz every single pimple, clogged pore, and nosehair will be sharp as a tack.

    Ta mate...so then using them with TC x1.4/ x2 wouldnt be out of the question as a small amount of softening might be a good thing in portraits ?

    Understanding of course that this will slow the lens a stop or 2.

    goose, I don't believe the 1.4 or 2x converters will work on the 100mm 2.8 lens. They're only designed to work on a limited number of zoom and large prime lenses.

    Oh sure, 100mm is a terrific focal distance for a 1.6x. 160mm, duh. But...since you'll have a 70-200/2.8 IS already on yer camera, you can hit and run right past it in both directions :D

    I also think the 70-200 is a far superior portrait lens than the 100 macro, for the reasons I mentioned above. Not that the lens isn't sharp...it is, and actually rivals a lot of primes...just that the overall image quality out of that zoom is so sexy silky smooth, it just makes you want to lick your monitor.



    :uhoh






    hmmm...i reckon I ought to take a couple of comparison shots with both the 100/2.8 macro and the 70-200/2.8 @ 100 so you can see what I mean. Maybe if it's not raining tomorrow, I'll do that for ya. It'll only cost you one 64oz beer. It probably won't be a portrait, cuz I can't get people to sit still while I swap lenses, but I'll try to set up a still life that gives you an idea of sharpness, smoothness, and bokeh.

    on the other hand, the 100/2.8 macro is a great macro lens, and the 70-200 isn't.
