About the Sigma 100-40mm F/5-6.3 Contemporary
The Sigma 100-400mm Contemporary is one of Sigma’s intial lens launch of their new generation of lenses. This lens really set the bar much higher for Sigma and let the consumers understand that they were serious about improving their lens built quality as well as the optics.
The purpose of the Sigma 100-400mm was to bring to the market, a lens which allows you to have a compact size, but amazing reach. This lens really delivers being that it’s so light weight and small. It’s really the perfect lens for a lot of people who don’t like using the heavier 70-200mm lens but still need the reach.
When using the Sigma 100-400mm Contemporary, you can expect the same great build quality you have been seeing from Sigma recently. Although the lens is not a fixed aperture, it still has the smallest difference than competitors. F/5-6.3 is a very short window so you won’t see a dramatic decrease or increase in light when zooming in and out. This is extremely beneficial in our opinion considering you’re able to go from 100mm to 400mm on an extremely lightweight lens.
We wouldn’t recommend this lens to be used indoors. It’s definitely something you can take outside and use for so many different situations. You will be pleasantly surprised at just how sharp this lens is, how lightweight it is, and just how versatile it can be even though it’s a 100-400mm focal length.
