How to increasr magnification for macro photograohy?


#1
Hi I am currently using the 100 mm l f2.8 on a 7d but I'm abit confused with telecovertor and extension tubes, I want to increase magnifications to 2:1 2x lifesize so what should I buy in order to achieve that?

This is a bellows (the thing with folds that can extend or retract):

This is a Raynox closeup lens convertor:

Teleconverters gives you magnification by "extending your focal length" and also increase your working distance.
Extension tubes and bellows gives you the ability to focus closer, so your camera/lens can get physically closer to the subject, thereby giving you greater magnification by letting you get closer.
Some macro folks use both at the same time.

Oic so the bellow looks too big, I think I will go with the extension tube and extender. Any nice brands to recommend? Im only looking at 2xlifesize magnification..

I don't do prints I usually just crop out but it's still too small that's y I wanna have 2x magnification
you already have 7D and a 100mm marco lens, which able to to 1:1,

you can't crop out a 2:1 from a 18MP camera?

since you are not doing any printing, how big are the images you want to fill on your monitor?

To achieve 1:1 magnification, set your lens to Manual Focus and turn the focusing ring to minimum distance. Move your camera and lens to focus the object till sharp and snap.

Yeah but that's not what he's asking. :)

How about combining both tubes and Raynox? Does anyone have any experience with both together? Thanks
