Clear sharp focus, maintains communication and auto focus with Sigma 105mm DG EX HSM lens.
on February 20, 2016
I am fairly new to photography but spent an hour or so shooting almost four-hundred macro photos in a local college conservatory; everything from hydrangeas, to begonias and orchids, to succulents.
This really extends the range of my Sigma 105mm DG EX HSM macro lens (does not work with my 24-70mm DG EX HSM lens, will not physically attach). It increases the magnification (1.4:1), but also increases the minimum focal distance slightly, which can be nice as you can keep a little more distance between you and your subject. Focal depth is extremely narrow in the macro range, but opens back up once you are a foot or more away from the subject. Focus at long distances is still sharp and you can still maintain a wide depth of field.
It is definitely more difficult to maintain stability at close distances, handheld can be very challenging near the minimal focal range. There are a bunch of affordable options on Amazon for macro focusing rails, but I think a simple monopod will be sufficient as certain shots are easier to get by manually focusing and rocking forward and backwards slightly to get the correct plane of focus.
