This is a serious bit of kit it's just stunning the only bad point is that it's so heavy this is a lens for Charles atlas !!!. Now I've got the bad point out of the way I took the lens and my Nikon d5600 out in the midday sticking it into hedges to get bug shots I will admit I had to bump the iso up...

Medium tele macro lenses are among the most popular prime lenses - they are long and fast enough for decent portrait photography and offer a sufficient working distance during macro sessions compared to shorter macro lenses.

The Sigma lenses are becoming my favorite. That is a hard statement consider I am team Nikon everything. I had a Nikon macro and it worked okay, but the motor broke and I returned it. This gem was on sale ($400 off!) so I gave it a go. I am so glad I did! The clarity and Bokeh is amazing.

It felt so cheap in comparison to my Nikkor lenses. I was trying to avoid spending an extra money to get the Nikon 105 micro and this lens is just not worth it.

This large aperture medium telephoto macro lens offers advanced performance of close-up photography. Sigma's own proprietary OS (Optical Stabilizer) system enables handheld close-up photography.

Super sharp!! Great lens all around. It does have a clunking sound when the lens is off the camera body but this is normal and does not mean the OS is broken.

Great lens for macro but not for portraits what i have observed is that it struggles a little in auto focus also the optical stabilisation is bit noisy. Plus the lens is not weather sealed Sharpness is less than that of the canon.

If I could give this no stars I would!!!!! After receiving this lens from overstock I quickly realized it was a grey market lens and that I couldn't even register for the warranty because it's for another country and I can't even read the language!!!!!!
