The two millimeters may seem trivial, but for those who have shot events and indoor settings (or even just landscapes), that extra wideness, however trivial it may seem, makes a tremendous difference.Īgain, we are not trying to speak poorly of what Sigma accomplished - it's just that 16-30mm would have been far more versatile and preferred. It's just that, if we are going to use this lens as a standard zoom for what it was designed for- events, weddings, concerts, etc.- we can't help but feel 18mm is not wide enough. We aren't taking away from Sigma's incredible achievement there. Yes, it's a zoom lens with a constant aperture of F1.8. While this may come across in bad taste to some, we couldn't help but be underwhelmed by the zoom range. *The lightpole really is crooked like that - not the lens's fault! First, here's the consolidated photo, which you can view a much larger version simply by clicking on the image below: gif slideshow - we decided to include both. Depending on what you prefer - the one photo or the animated.

The below are from the same set of images (all shot on a tripod at F10, ISO 100, and 2s Timer using the K-3). As such, we will show the following zoom range not just using the min and max on the Sigma, but comparing also what the Sigma's zoom range looks like versus 16mm through 50mm per Pentax's premium standard zoom. Should the Sigma 18-35 be your first zoom (as a prime aficionado) or "just another" lens you're feeding your Lens Buying Addiction with, we wanted to give a quick demonstration of what you can expect regarding the field of view differences throughout its zoom range from widest to narrowest (18mm to 35mm).Īdditionally, this lens is going to be considered by many of you against other alternative lens options- namely the DA* 16-50mm F2.8, FA 31mm F1.8 Limited, and HD DA 20-40mm F2.8-4 Limited lenses from Pentax, all of which will be compared to in this review later on. The 18-35 F1.8 is peculiar because at a constant F1.8 aperture across the entire zoom range, it may certainly be described as "a bag of primes." Before we get to the sharpness and other image quality aspects to assess its "prime-ness," we wanted to see what this Sigma was all about in its most basic image quality facets.
