How to increase magnification in Macro setup?

[icecube4u]

I have a nikon D80 and use it for Macro when coupled with a Tamron 90mm. The details captured are quiet sharp but want more.

How can i magnify what i take with this setup? What's the best way to do this? Extension tubes, Raynox attachment....what?

Appreciate your replies!

close-up filter

Some people max it out using both macro filters and extension tubes on macro lenses but there will be a significant loss of light.

try extension tubes first, then add more and more and more
then bellows
until you buy a microscope

so considering the fact that i have enough light.....(flash(es)/ daylight/ studio lights).....extension tubes are a more logical choice since they would maintain the quality of the shots.
Thanks for the suggestions.

what about teleconverter? will TC increase magnification on Macro lens as well? eg. 1:1 lens, with TC 1.4x will give me 1.4:1?

anyone can confirm this?

Sorry TS, Since this regarding about increasing of magnification, I borrow this thread to ask my question. hope u dun mind.

Absolutely. No problem.

About your question below....for eg: if you are using a 90mm lens for the macro....with a 2X TC, the lens is effectively a 180 mm lens....hence a bigger focussing distance.....or does the focussing distance remain the same while increasing the magnification!!!! Dunno if someone can confirm that??? Looking for the answer too.

A 1:1 macro with a 1.4x TC will increase the magnification to 1.4:1 and loss of light at 1 stops, so a max f2.8 lens will drop to a f4. A 2x TC will be a 2:1. and loss of light at 2 stops, f2.8 drops to f5.6.

I don't think many ppl will use a 2x TC as the image quality will degrade too much for good macro work where sharpness of detail and is important.

Getting a macro close up to stack will shorten the distance you need to get to the subject, thus revealing about more details. However, DOF is going to be much thinner and you will need to have high shutter to compensate for the handshakes.

Using a longer lens with an appropriate close-up filter would give you better magnification. A 100mm with the Raynox will give u less magnification than a 300mm with a Raynox. I find myself often going to larger than life-size with a 75-300 + Raynox DCR-250 combi. However, note also that the larger your magnification, the harder it is to handhold and compose, especially at weird angles. =)

I think you can use a long lens with a reversed wide-angle lens too, though that'd give u very little working distance.

so EC14 will be a good enough and better choice for me then compare to EC20.

Depends on what you want to shoot. If you are shooting general insect macros, 1:1 should cover most of your needs. A 1.4x TC will help when you want to fill the frame for smaller insects or detail abstracts of larger insects (e.g. dragonfly wings).

If you want to do really high magnification in the field, then a reverse lens combination will probably get you more magnification for the buck.

Has anyone tried Kenko Pro 2x or 3x teleconverter with a macro lens?

Samples images are appreciated pleassse.

not advisable... IMHO, 1st of all Kenko is 3rd party I doubt it will give you good glass maybe just decent (I dun noe, I dun use)... 2nd 2x or 3x will drop at least 2 stop, 3rd degrade of IQ may not be too acceptable...

Hi all,
You can consider the Raynox macro converter lenses such as DCR-250. Please note these are not close-up filters which are actually simple magnifying lenses only.
For details, see below:

Cheers.

I'm thinking more of using a teleconverter as the minimum focus distance remains the same. However, the Raynox seems good too as the IQ is good but MFD is shortened.
