I see your pictures on your site and think that unless you plan on doing other types of pictures then autofocus speed is probably not much of an issue. Something with a long focal length like birding would be different but your site contains no birding pics and the 18-35 would be a terrible choice. I do not really need 11+ try's of the same shot to get a useful pic. What I am saying is that the ability of this lens to focus on fast moving cars would not be a factor for me.įor one thing at this focal length most of the example shots could have been done manually at infinity or close to it. That is why I specified AF speed (which is the subject of this thread). Apart from the fact my Sony XZ1 Compact produces decent pics too (yeah, I know - blasphemy). Size and weight? I do not shoot touristic pictures, since it is boring. ![]() To cover 16/30/50/85 with native lenses you get two Sigmas 18-35 and 50-100, do not have zoom with your legs. Try focusing on different objects indoors at home, it should give you an idea of what the lens/adapter can do with indoor lighting as far as AF goes.Īs far as F1.8 you can get only 30/50/85 + Sigma 16 1.4 primes for A6500. I use flexible spot focus area to make it easier to focus accurately on the face of one of the competitors. You usually don’t need lightning fast focus at these events anyway, you just need it to be accurate and reasonably fast. I have to think that if the Sigma 18-35 1.8 focuses quickly and accurately in good light, it should do fine at indoor judo tournaments. I’ve used both the MC-11 and Metabones Speedbooster adapters with both lenses, and both focus very quickly even in the relatively low light of a school gymnasium or sports arena. I’ve not used that specific lens, but I’ve shot thousands of photographs at indoor JiuJitsu tournaments with the a6300 using both the Tamron 70-200 2.8 VC and Canon 50mm 1.8 STM. ![]() ![]() Its fast aperture, advanced optical design, and solid build make it a top performer in its category and a favorite among photographers.These were shot in perfect light conditions, wonder what about indoor judo tournament? Will there be enough light to make the AF work as well good? The Sigma 18-35mm f1.8 Art Lens is a versatile lens that is ideal for a range of photographic applications, including landscape, architecture, portrait, and street photography. The lens also features a brass bayonet mount for enhanced durability. The lens barrel is made of a Thermally Stable Composite (TSC) material, which is resistant to temperature changes, making it less susceptible to thermal expansion and contraction than traditional materials. The lens also features a Hyper Sonic Motor (HSM) for fast and quiet autofocus, along with a manual focus override for precise manual focusing. ![]() The lens also features a sophisticated optical design that includes four aspherical elements and five Special Low Dispersion (SLD) glass elements, which work together to minimize chromatic aberration, distortion, and other optical aberrations, delivering sharp, clear, and well-defined images. One of the key features of the Sigma 18-35mm f1.8 Art Lens is its fast maximum aperture of f1.8, which makes it ideal for low-light photography and creative depth-of-field effects.
