To achieve higher magnification you can use extension tubes, reversing rings and lens couplers. Extension tubes are the easiest to work with because they have electrical contacts, which connect your lens to your camera. This way you can still retain connectivity and functionality like aperture control. You can have a look at this question: How can I ...


Yes, extension tubes or reversed lens. The greater the magnification, the higher the actual f/stop number goes. Things get harder at such magnifications. Use the 105 macro lens, forget the 18-200 for this. Or for "larger than macro lens", this is becoming very popular too (on the long macro lens): ...


Yes, you may use the MP-E 65mm lens on a Canon T3. No, you do not need any adapters. Just realize that the MP-E 65 is a different type of lens than what you are probably used to. Not only is it a manual focus only lens, but at each magnification setting there is only a single distance the lens is capable of focusing. The way most users focus is to set the ...


As agf1997 says, minimum focus distance for macro lenses varies somewhat with lens design, however as a rule of thumb you can expect the minimum focus distance (i.e. minimum working distance) to be roughly the same as the focal length of the lens (assuming 1:1 magnification here). Hence a 300mm lens with a whole lot of extension tubes (as a silly example to ...


When a macro lens has a reproduction ratio of 1:1 an object with a given size will be reproduced at the image plane at the same size. This is irrespective of the focal length. The only difference is that a longer focal length will afford you the ability to achieve that reproduction ratio at a greater distance than the shorter focal length. The precise ...


You should create your own custom profiles for the inverted lenses.
