    It's still important. Your question is just like telling a birder to shoot with short lens and crop later.

    Sensor and film is the same, only that digital can crop at ease in means of a PC, if using film, you had to crop in the dark room by means for enlarging the part of image that desire to the photo paper.

    Most of the wonderful macro subject is very tiny and macro lens itself can't reveal the beauty of it.

    if u wanna shoot macros, please don't rely on AF. use MF instead.

    if you worry about budget, shoot with reverse lens setup. i have one where it cost me $45 for the lens. you have to buy the reverse ring & maybe a step-up/down ring (depending on the lens you buy).

    20mm reversed on a 100mm will give you a 5:1 ratio. Watch out for vignetting.
    Errrr ... how do you reverse mount a lens since there it is not threaded on the front. Thanks !!

    To reverse a lens onto another lens, you need a male to male coupling ring.
    To reverse a lens onto the camera body, you need a macro reverse adapter.

    Personally, I use Tamron 90mm + Kenko 2x TC. It'll give 2:1 magnification at the closest focusing distance. I got reasonably good results from it.

    There are custom made reverse rings available in the market for almost all camera system to reverse mount a lens.

    Just point to note that, reversing mount a wide-angle lens will allow you to get a bigger magnification.

    Ya, forgotten about that. Bellow's focusing rail is very useful in high magnification.

    Yeah, I get what you mean but just some thoughts.. What I meant was the term 1:1 doesn't have to be that strict anymore, does it? If you use a smaller sensor with higher pixel density, the angle of view would be reduced, so effective viewing magnification would be higher, right? Let's not talk about drastic differences in magnification ratio.. so, does it matter much if it's 1:1.134 or 1:0.973 or 1:1.0003 for digital?

    If you use bellow, then you don't need to get the MPE65 anymore.

    One of my ex-colleagues made adapters to mount Leica microscope objectives onto his SLR.

    Ya, it doesn't matter at all with little difference, difference sensor size will had difference 1:1 magnification rate. Sometime too small to tell the difference.

    Actually MPE65 is using the concept of a bellow. One of my friend using 4/3 system just started experiment it too and easily get 4:1.

    But it seem quite bulky to use in the field.

    Yeah.. bellows are always cumbersome to use in the field. I remember seeing a variable extension tube but can't remember the brand. Tried to do a web search but no avail.
