I can easily say this lens has outperformed all the previous Sigma lenses that I have tried. I think Sigma is aiming big in this one giving the impression you don’t need a prime lens to shoot prime photos. This lens happens to be the only lens in the world that maintains 1.8 aperture through-out zoom range right now.
Only a few lenses come with an aperture this wide. This is beneficial because it lets more light pass through the lens before taking a photo but it increases depth of field; you have to be very specific when taking photos with this aperture. The narrowest aperture on the lens is 16 which isn’t bad but standard lens’ normally have 20 – 26 aperture.
One of my favourite aspects of this Sigma lens was how sharp it was, the photo above is Audi’s cursor button and it’s pretty small. The spikes on the cursor are tiny yet the lens managed to get a really good close up. I’ve taken other photos showing how sharp the lens is at the gallery on the bottom of this post.
Took this photo at Villa Babak, notice how sharp the photo is at 1.8 aperture but also notice how strong the depth of field is in the photo. Of course the more you narrow the aperture the shallower the depth of field becomes. So there’s also the option of widening the depth of field in all lenses.
This shot was taken while the Porsche was speeding and it turned out crisp. Of course you can’t just buy the lens and expect it to perform that way, you have to first configure the settings based on your atmosphere. For fast-moving objects make sure you have a high F-Stop, somewhere around 150+. It depends on how fast the object is moving.
Below are some sample shots I’ve taken with this lens:
Overall the lens has exceeded all my expectations, it gives you the features of the prime lens but for a fraction of the cost (KD 229), available at AABWorld. Keep in mind the lens isn’t full frame and it’s pretty heavy weighing 800 grams. It is not your all-in-one lens, for that you should get a lens that has a bigger range. It’s a lens for macro shots, sharp photos, intense close-ups and strong depth of field photos.
