Today I’d like to share my thoughts about a lens I’ve had for quite some time now. Yet I’ve been using it extremely rarely for the past couple of months, perhaps even for the last two years. I’m talking about the SIGMA 105mm f/2.8 EX DG OS HSM Macro! For my test images, of course, I used once again my Canon 5D MarkIII camera.
The lens comes with a good build-quality and a very good light intensity level of 2.8. The close-focus level is 31cm, which of course is the best prerequisite for a good Macro lens. It’s perfect for wildlife and still life photography, but also for capturing motion. It’s also a good choice for portrait photography. The lens weighs 725 grams, but in this case high quality has some weight. 😉
I’ll briefly explain to you the abbreviations used for lenses. Many of you may know them already, but for all those who don’t:
EX: EX refers to fixed focal length
DG: DG lenses can be used on full-frame cameras
OS: means optical image stabilization
HSM: refers to the Hyper Sonic Motor – on HSM lenses a motor is used that is powered by ultrasonic waves.
The most important thing about this lens is, of course, its macro function! In short, you’re going to enjoy taking close-up shots with this kind of lens! The f/2.8 open aperture, however, can barely be used for macro shots as this will reduce the depth-of-field too much. Still this lens guarantees very sharp photos. The aperture can be closed down to f/22. From f/18 blur becomes clearly visible.
Of course, the Sigma 105mm Macro is also a classical tele-zoom lens. Its macro function is like a bonus. Speaking for myself, I like the 105mm focal length a lot. Even with the 24-105mm Art I’m a big fan of a fixed focal length. With APS-C you are sure to get more than 105mm.
I’m very satisfied with the image quality of this particular lens. Chromatic aberration is a key issue with wide-angle lenses. With an open aperture some slight color distortion is visible in some blurred areas; however, this decreases the more you close the aperture. I’m happy with the general level of sharpness of this lens and I also like its bokeh.
I’ve attached some images for you which I took with the SIGMA 105mm f/2.8 EX DG OS HSM Macro. By showing you a mix of macro and tele-zoom pictures, I’d like to give you an idea of the versatile character of this lens.
Who among you enjoys taking macro pictures? Which are your favorite lenses for that? Tell me your thoughts on Macro. I’d like to hear back from you.
