Macro - How to get more than 1:1 ?

Can try going through the faq created by megaweb here.
Each having their pros and cons.
But generally as you go past 1:1, AF tends to hunt and kinda hamper shooting. It is kinda useless to me and i would not miss the function too much.
On the whole there are two groups of devices that gives u mag past 1:1 : one adds more glasses your existing macro lens, and another adds nothing
Closeup filters are convenient add ons, but the quality of shots hinges on the quality of the filter. generally the more expensive dual element acromats are the better glasses. The issue of decreasing working distance. I am sure u have some experience with Raynox filters already. For flat field macro lenses u might have to reverse mount the filters.
Alternatively u can reverse mount a wider angle lens onto the front of a lens and act as a *multi-element close up filter* which in any case u still have AF and metering functions.
U can reverse mount the lens directly on ur camera but you would have lost the AF / metering that u wanted on ur D80
The greatest advantage of teleconverters IMO is the increased working distance. The additional of glass elements will like close up filters soften the final picture. I tried using a Nikon TC2EII before but the fine details of macro work are softened ( dats why currently scouting for a longer focal length macro
)
Extension tubes / bellows do not have any glass elements in between and removes the worry of having additional glass element in front / between your already tact sharp macro glass.
Issues of decreasing working distance again, and bellows can be really a pain in the a** to deploy outfield, and is an overkill if you need any magnification less than 3x. Extension tubes give abit more flexibility but a shorter extension will give less mag.
Either way nothing should go too wrong and will give u the results :bsmilie:

1:1 - the subject will appear at its size in the sensor of the camera. If it's 1:5, it will magnify the subject 5 times. So, immagine if you are taking a shot of an ant using a macro lens with 5x magnifiation, you can even see the eyes of this tiny creature. Just my understanding.

I thought it is supposed to be 5:1? But as long u can get the idea across is fine.
Reverse mounted lens.
20mm reversed on a 100mm will give you a 5:1 ratio. Watch out for vignetting.
There is a BR2A Nikon adapter that connects the 52mm lens thread to the body ( reversed mounting of the lens ) Ideally you should use the wider prime lenses such as the 20mm to 50mm. I think one can reverse a 55mm and get magnification as well. ( 16mm onwards the lens element start to protrude, and not to mention the fixed lens hood )
If your lens does not have a 52mm thread, then you will need to step it down to 52 mm with a step down ring.
You will however lose all metering. And in addition to that, you will be manually stopping down the aperture, which is not easy to shoot especially moving subjects when you are already tied down on getting focus manually, and yet plagued by the dim viewfinder.

1:1 means the size of the sensor = size of the object if it fills the frame.
meaning, if u have a sensor that's 36mm long and u can fit an object that's 36mm long edge to edge and still achieve focus, you have a 1:1 macro set up.
something like that lar.. ;p

Hey Ryan
Thanks for your detailed explanation.
Ha, now the next queston. What brand extension tubes I can get and roughly how much?
Are there any compatability problems with different brands for using with my lens and the D80?
I have tried Kenko and Triplus ( essentially they are from the same makers. The exterior the interior exactly from the same mold save the name imprinted , heck even the fonts are the same. .. )
The each offers a DG set of three extension tubes of varying extension length. The Kenko Uniplus works well as well offering 25mm by itself. ( I got a used Uniplus tube for about 30 bucks on CS previously
)Here is a shot of my Kenko DG set, showing the 36, 20 and 12mm components.
Replace the Kenko name with Triplus and u have a Triplus extension tube set.
You can check out the BnS section here for better deals. The new ones are much pricier and may cost ard 180 - 190 for a set of 3. There are no lens elements so there is not much worries on used sets.
Although they claim to not perform AF on AFS lenses but only with the older non-AFS lenses, somehow it works for my 105mm VR ( I tried the 18-200mm before and it worked as well) but of course slower. But AF is not really a necessity. Likewise the VR which works as well is not really critical. Importantly they will still resume metering with your D80

Yes, you can try extension tube, bellow, high value diopter closeup filter or reversed lens technique. Auto focus ? not possible.
I wonder how you all do manual focus, the yellow led keep flashing,hmm.
Yesterday, I spotted a spider web with spider and tried to shoot it.
I was using auto focus, the lens/camera coudn't find the web, haha...have to manual focus then when i get the web image, changed to auto focus and shoot.
End result? Blur image due to camera shake...i guess one cannot be lazy, probably had to use a tripod for the above shoot.

$30 bucks for a used one, good news for me coz photography ain't a cheap hobby :bsmilie:
PS: Wondering will it work with all my lenses, Tokina macro, Sigma 70-300, Tamron 17-50 and Nikon 50mm?
Is 1:1 that important if you're not shooting film? What is life-sized in DSLR context?
